Engineering sceince - Math Problem Example 2 =0.5 * 1.5*238.762 =42754.7532 Joules = 42.7547532Kilojoules Question 2 Potential energy, PE = Therefore, PE = 440*9.8*3.5 = 15092N Kinetic energy, KE = = =9295N Total energy = 9295 + 15092 = 24387 joules Assuming all the energy is converted to KE since there is negligible friction, the final velocity can be gotten by = =110.85 Therefore final velocity, = 10.53m/s Task 3 Question 1 When a net force is acting on an object is proportional to the displacement of the object from the equilibrium, a simple harmonic motion occurs. This is as a result of the insignificance of the force acting on the object (in this case it is zero). A sinusoidal curve illustrates, which is presented as a function of time, illustrates the displacement of the object when the force is acting on it (object). Ideologically, this signifies the model of oscillatory motion. This represents ideologically the model of oscillatory motion. ... Question 2 Angular velocity = 3000rpm = 314.16rad/s Maximum velocity, v =A =0.24*314.16 = 75.4m/s Maximum acceleration is given by 2 =0.24*314.162 = 23685.653376m/s2 =23.683km/s2 Maximum theoretical force F= ma from Newton’s second law 0.28*23685.653376 = 6631.98N Therefore maximum force is

Evaluate methods of managing and developing human resources Essay

Evaluate methods of managing and developing human resources - Essay Example herent of its human resources who are usually motivated and encouraged to commit to the workforce and in this way they feel the organization is valuing them therefore; they play an important role in the organization. For an organization to succeed, it is important that it motivates its employees and have a high-level job involvement. An organization is able to experience increased productivity if it motivates its employees and makes them enjoy their work. Workers who have the ability and desired skills for performing a certain job have the great chance of increasing the company’s productivity. Therefore, companies that recognize the efforts of its workers are able to encourage its employees to meet and even exceed the expected productivity. One of the strategies that companies use to improve its productivity is developing its employees using several development programs such as education and training. During employee development, the manager can set various development goals for employees because the goals and training will enable the worker to reach his career aspirations. Moreover, companies that have invested in their employees through recruitment and training, they usually lose when the employees leaves and joins other companies. Therefore, it is important for companies to try and retain their workers and make them loyal in order to help it in achieving goals by reducing the costs incurred when recruiting new employees. Loyalty can be enhanced by offering recognition of the superior performance, and this will enhance satisfaction inside the workers’ mind. Induction is also used as a training method because it enables a newly recruited employee to catch up and become reproductive quickly. Induction is importa nt because it prevents the organisation from costly mistakes that may be caused by the recruit. In addition, most managers use employee motivation and involvement to enhance their motivation at the workplace1. A motivated worker will show up at the
