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.
