The Similarities and Differences of Chapter 14 (Kinetics of a Particle : Work and Energy) and Chapter 18 (Planar Kinetics of a Rigid Body : Work and Energy) In the Mechanic Dynamics subject‚ monitored by Dr. Faisal Mohamad Ayob‚ I have learnt about the Kinetics of a Particle : Work and Energy of Chapter 14 and Planar Kinetics of a Rigid Body : Work and Energy of Chapter 18. Between these two chapters‚ I found out that they have some similarities and differences that can be compared. In Chapter

EXERCISE 8 - Rotational Dynamics‚ Equilibrium of rigid body 1. If the torque required to loosen a nut that is holding a flat tire in place on a car has a magnitude of 40.0 N m‚ what minimum force must be exerted by the mechanic at the end of a 30.0-cm lug wrench to accomplish the task? 133 N 2. A steel band exerts a horizontal force of 80.0 N on a tooth at point B in Figure 1. What is the torque on the root of the tooth about point A? 0.64 Nm 3. Calculate the net torque (magnitude and

ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

electrons to have a unit charge. This bold‚ controversial stroke eliminated the fractionally charged electrons that had some support in other laboratories. Alternatively‚ theorists suspended various disbeliefs to create the discreteness of quantum mechanics and a relativity where time is suspect. By using fundamental presuppositions containing elements of symmetry‚ causality‚ completeness‚ continuum and invariance‚ Einstein concluded that "the noblest aim of all theory ... is to make these irreducible

Biomechanical principles are what introduces the human body to motion‚ so the tennis biomechanics is essentially the science mechanics tennis technique. Tennis is a game in which two or more players hit the ball with rackets over a low net that is stretched across a court which is usually artificial surface. The tennis serve begins from the feet hitting the ground then continues up through the torso to the shoulders‚ then moves to the arm and then wrist. It continues right to the point when the ball
