  • Vector Addition

    Addition of two vectors may be affected with the help of parallelogram law of addition.

    The resultant(sum) vector R’ of A’ and B’ is the diagonal of the parallelogram of A and B of adjacent sides.

    The triangular law of vector addition follows the parallelogram law which states that: if the tail-end of the vector is placed at the arrow-head of the vector, their resultant(sum) vector is drawn from the tail of the first to the head of the other.

    see the figure below

    Subtraction of vectors

    The figure below shows addition of vectors in reverse direction of B’ vector.

    The process of subtracting one algebraic quantity from one another is equivalent to adding the negative of the quantity to be subtracted. in essence, a-b = a+(-b)

    The negative vector –B‘ of vector B is defined as a vector of the same magnitude(length) but in opposite direction.

    Resultant set of forces

    Two vectors are said to be equal if they have the same magnitude and direction. If two vectors A and B are parallel, the magnitude of vector sum C equals the sum of magnitudes of A and B.

    consider the vectors A and B represented below

    The resultant vector C will be represented by a single vector as shown

    If two vectors are antiparallel, the magnitude of a vector equals the difference of the magnitudes of A and B

    The diagram below shows vectors that represents forces acting in opposite direction

    The resultant vector is smaller than the larger vector and bigger than the smaller vector and moves in the direction of the larger vector.

  • Conical Pendulum

    Conical Pendulum

    The diagram below represents a body of mass m moving on a horizontal circle with a constant velocity v at the edge of a cord of length L.

    As the body swings around it’s path the cord swings over the surface of a cord. The cord makes an angle θ with the vertical so that the radius of the circle in which the moves is R=Lsinθ and the magnitude of the velocity is given by:

    where T is the periodic time.(time for one complete revolution).

    The forces exerted on the body when it is in the position shown are it’s weight(mg) and tension(T) in the cord.

    Tension T can be resolved into horizontal and vertical component Tsinθ and Tcosθ respectively.The body has no vertical acceleration, so the vertical forces Tcosθ and mg are equal in magnitude.

    The resultant inward radial(centripetal) force is the horizontal component Tsinθ which is equal to the mass(m) multiplied by the radial or centripetal acceleration.

    From linear motion, F=ma.

    but since the motion is circular; a=v2/r

    hence, the expression for the horizontal motion.

    For the vertical forces;

    Tsinθ = mg ……………………………….. (ii)

    When the equation (i) is divided by equation (ii) the result is:

    but from trigonometry, sinθ/cosθ = tanθ; hence

    When we make use of the relation r = L sinθ and v = 2πLsinθ/T

    The equation becomes:

    This leads to:

    hence we have;

    dividing by sinθ on both sides;

    from the equation tanθ = sinθ/cosθ ; 1/cosθ = tanθ/sinθ and therefore:

    and hence;

    and making T the subject of the formular, we have;

    which will results to:

    The angle θ depends on the time of revolution T and the length of the cord.

    For a given length L, cosθ decreases as the time is made shorter and shorter and the angle θ increases. The angle θ never becomes 90o sinces this requires that T = 0 or v= .

    The largest possible value of T is given by T=2π√l/g which occurs for a very small angle θ for which cosθ=1 and therefore:

    5 years a go

    When is the last time you took a risk? How did it work out?

    I left a toxic working environment but I have never regretted that decision despite the turmoil and pain I went through. It is better to suffer for a while and make changes rather than live in a misery.

    The effects of a toxic work environment can extend beyond the workplace and significantly impact an individual’s personal life in various ways. The earlier you withdraw from such environment the better. People with great potential have been drained in such places and they eventually becoming useless to both their employer, to themselves and to society at large. The effects affects physical , emotional, mental and spiritual health health such that you can have long lasting effect that affects even your social life. Here are some known effects that are common to many people from such environment.

    In general, the effects of a toxic work environment can penetrate every aspect of an individual’s life, affecting their mental, emotional, and physical well-being. Recognizing the signs of toxicity and taking steps to address them is crucial for preserving one’s personal health and happiness.

    Health work environment is very important

    A healthy work environment is described as one where people are valued, treated respectfully and fairly, where personal and professional growth is supported, communication and collaboration are championed, and there is a sense of community and trust at all levels, which enables effective decision-making. A healthy work environment comprises competent employees, appropriate workloads, effective communication, collaboration, and empowerment, which leads to positive outcomes for patients, employees, and the organization(Donley J. The Impact of Work Environment on Job Satisfaction: Pre-COVID Research to Inform the Future. Nurse Lead. 2021 Dec;19(6):585-589. doi: 10.1016/j.mnl.2021.08.009. Epub 2021 Sep 4. PMID: 34512206; PMCID: PMC8416300.)

    Increased Stress and Anxiety

    Dealing with constant negativity, criticism, or hostility at work can lead to chronic stress and anxiety. This can spill over into personal life, making it difficult to relax and enjoy time outside of work.

    Strained Relationships

    High levels of stress and frustration from work can strain relationships with family members, friends, and romantic partners. Individuals may become irritable, withdrawn, or emotionally unavailable due to the toll of their work environment.

    Poor Work-Life Balance

    Toxic work environments often demand excessive hours or emotional labor from employees, leaving little time or energy for personal pursuits, hobbies, or relaxation. This imbalance can lead to feelings of resentment and dissatisfaction with both work and personal life.

    Physical Health Issues

    The stress and anxiety caused by a toxic work environment can manifest in physical health problems such as headaches, muscle tension, fatigue, and sleep disturbances. Over time, these issues can contribute to more serious health conditions if not addressed.

    Negative Self-Image and Self-Worth

    Constant criticism, micromanagement, or bullying in the workplace can erode an individual’s self-confidence and self-esteem. This negative self-image can spill over into personal life, affecting relationships and overall well-being.

    Decreased Enjoyment of Activities

    When work-related stress and negativity dominate one’s thoughts and emotions, it can become challenging to find joy or fulfillment in activities outside of work. Individuals may lose interest in hobbies, socializing, or other activities they once enjoyed.

    Impact on Mental Health

    A toxic work environment can exacerbate existing mental health issues such as depression, anxiety disorders, or post-traumatic stress disorder (PTSD). The constant stress and negativity can make it difficult to cope and may require professional intervention.

    Difficulty Switching Off

    In today’s connected world, it’s often challenging to disconnect from work, especially when faced with a toxic environment. Constant emails, messages, or thoughts about work can intrude into personal time, leading to feelings of overwhelm and burnout.

    conclusion

    For the sake of your health, wellbeing of your loved ones and your influence , better start thinking how to leave once you realize that you are in a toxic work environment.

  • Starting a business

    Starting a business

    Describe a risk you took that you do not regret

    Doing business was better than all things I tried to do. When you are an employee, you are basically a consumer. All you do is do routine things and wait for a salary that can barely meet your wants. All you have is some little cash to cater for your basic needs for the next thirty days. You creativity is limited and your ideas are usually suppressed because you have to work and act within what is accepted by your employer.When you have great ideas, you can’t try them out but in business world, you have unlimited opportunities to succeeded as you can try new ideas that randomly comes to your mind.

    In employment, one can keep postponing good ideas that could change their lives and that of others because they focuses mostly on fitting their immediate needs to their salary and could wait for ever to start out on something big.

    Overall, while traditional employment provides stability and a steady income while business ownership offers individuals the opportunity to pursue their passions, create wealth, and make a meaningful impact on the world around them.

    The importance of business over employment lies in the opportunities it offers for personal and economic growth, innovation, and wealth creation. Here are some key points highlighting why business ownership can be more advantageous than traditional employment:

    Owning a business provides the opportunity to create wealth rather than simply earning a salary. Successful businesses can generate significant profits, leading to financial independence and long-term wealth accumulation.

    Business owners have greater control over their work environment, operations, and decision-making processes compared to employees. This autonomy allows them to pursue their vision, values, and goals without the constraints of organizational hierarchy.

    Businesses are often engines of job creation, contributing to employment opportunities for others in the community. By starting and growing a business, individuals can directly impact job creation and economic development.

    Entrepreneurship encourages innovation and creativity as individuals develop new products, services, and business models to meet market demands. This pursuit of innovation can lead to groundbreaking advancements and industry disruptions.

    Business owners have the flexibility to set their schedules and prioritize tasks according to their personal and professional needs. This flexibility can lead to a better work-life balance and increased job satisfaction.

    Building a successful business allows individuals to create a lasting legacy for themselves and future generations. A well-established business can be passed down to family members or sold as a valuable asset.

    While traditional employment provides a steady income, business ownership offers the potential for unlimited earnings and financial independence. Successful entrepreneurs can build scalable businesses that generate passive income streams and wealth over time.

    Running a business requires individuals to develop a diverse skill set, including leadership, problem-solving, communication, and resilience. The entrepreneurial journey can foster personal growth and self-improvement.

    Businesses play a vital role in contributing to the economic prosperity and social well-being of society. They create value for customers, stimulate economic growth, and support charitable initiatives and community development projects.

    While business ownership entails risks, such as financial investment, market competition, and uncertainty, it also offers the potential for high rewards and returns on investment. Successful entrepreneurs are willing to take calculated risks to achieve their goals.

    1. I took wrong actions

      Write about a time when you didn’t take action but wish you had. What would you do differently?

      The fear of being caught in a trap if non action has caused me to make decisions in haste hence doing wrong things. One such a mistake was pursuing hire learning instead of investing in business first. I wish I heard in invested money to bring more wealth than pursue knowledge because we have soo many educated but poor forks

    2. Speeding cars

      Speeding cars

      What makes you nervous?

      I have never understood why we need to move that fast in most of the time, but whenever am in a very fast moving car and am not the driver, it really makes me nervous.

      I always wonder if a speeding driver really have a hint of the long time effect if peradventure he makes any mistakes. That a few seconds of stupidity can have long long term effect like life time disability, orphanage to children whose parent’s life is halted suddenly, making the car we cherish unroad worthy, traumas to survivors etc.

      According to the World Health Organization (WHO), road traffic injuries caused an estimated 1.35 million deaths worldwide in 2016.Low-income countries now have the highest annual road traffic fatality rates, at 24.1 per 100,000, while the rate in high-income countries is lowest, at 9.2 per 100,000.(Wikipedia, accessed 22/04/2024)

      Countries with the most of accidents per year by 2019:

      United States 1,949,000
      Germany 300,143
      Turkey 174,896
      Italy 172,183
      United Kingdom 123,212
      Canada 105,791
      Spain 104,080
      France 56,006

      The United States has more than four times the number of car accidents of any other country in the world. China had the eighth-highest number of motor vehicle accidents in the world in 2018. It reported approximately 212,000 accidents.

      Considering the devastating long term effect of road carnage, i think no car manufactured should exceed 80 km/hr.

      Thinking about all this, I wonder if we should be having fast moving vehicles in the dry land, that is why it makes me so nervous.

    3. Sleep

      How do you unwind after a demanding day?

      Or how else can one recover from mental stress and bodily fatigue? Is it not by sleeping and allowing your brain to rebuild.

      Sharing some romantic moments with your beloved ones is also one of the best ways of relieving yourself off the stressful day. It is much better when you both love each other.

      If you have a loving partner, you are blessed. Romantic relationship with somebody you love is a great help against emotional turmoils we go through each day.

      If you have a working relationship, guard it jealously, because it is precious.

    6. Social media

      Social media

      How do you use social media?

      I express my thoughts through social media and I find out other people’s thoughts from there. I read news and meet with friends. It is through social media that we can meet those old friends from childhood and reconnect. However, in social media we have met con men that sold us dubious deals.

      A place to market

      Social media is a useful tool for marketing because there are so many people there. Almost everybody that has smart phone has a social media account, may it Facebook, whats app, twitter, linked, mastodon etc. In Facebook you create awareness to a large number of people.

      A place to brag

      Social media is a source of self-pity and anxiety. People flashes in social media, they post nice places, nice cars and family and when you are not very well, you can feel like a failure because you will have an impression that your friends have advanced soo much. However, what most people will post on social media will not always match their reality.

      A place to reconnect

      Almost everybody is in social media, and so if you want to know whether your friend still exists, you can search them through social media. It is a place you can find people you have long lost in touch and seek to reconnect with them. However, social media can be so passive such that people dies and leave their image on social media such that you cannot tell whether they are dead or arrive. I have a case where i kept asking my college friend to call or text me and i wondered why they were not responding. i later learnt that they died two years ago but they left their flashy life on social media. They were people that looked successful but they died in misery. Therefore, social media can give false positives.

      A place of ideas

      Social media is a place where people express their ideas, tell us who they are and what they do. In fact, there is this habit of some employers stalking your social medial profiles to get a grips of who you are. In social media, we post our daily activities and so people can use social medial to decipher who you are beyond your professional outlook. But i dislike people who uses social medial to make professional judgement about workers because people should be let to be and have freedom of expression. Professional judgement should be confined to the work related contexts and the walls of an office.

      communication tools

      social media is usually used by people to drive their political, cultural or religious agendas. Even terrorists could use social media to advance their terror agenda and recruit others.
