The forces T2 and T1 are not forces on the pulley, but forces x Contents 14 Work, power and energy 221 14.1 Work done by force on a particle 221 14.2 Conservation of energy 223 14.3 Spring energy 224 14.4 Power 225 14.5 Kinetic energy of translation and rotation 225 14.6 Energy conservation with both translation and rotation 226 14.7 Energy and moment of momentum 227 14.8 Answers to exercises 229 Part III Problems 233 15 Statics 235

The sum of all the forces is zero. The sum of moment at any point O is zero. Problem 329 Equilibrium of Force System Two cylinders A and B, weighing 100 lb and 200 lb respectively, are connected by a rigid rod curved parallel to the smooth cylindrical surface shown in and β that define the position of equilibrium. Forces Fig. P-329 This book is helpful in semester exam. Where we can secure good marks.after solving no.of problems ,we will face the semester exam as well as other competive exam. GCSE Science Questions Pack 5 Pearson Publishing 01223 350555 9 Unit 3 Equilibrium and Turning Forces The centre of gravity of an object is the point through which the whole weight of the object seems to act. A metre stick supported above its Physics 1120: Rotational Dynamics Solutions Pulleys 1. Three point masses lying on a flat frictionless surface are connected by massless rods. Determine the angular acceleration of the body (a) about an axis through point mass A and out of the surface and (b) about an axis
