Problem 319 | Equilibrium of Concurrent Force System

Problem 319
Cords are loop around a small spacer separating two cylinders each weighing 400 lb and pass, as shown in Fig. P-319 over a frictionless pulleys to weights of 200 lb and 400 lb .
 

Cords loop around the spacer of cyliders

 

Determine the angle θ and the normal pressure N between the cylinders and the smooth horizontal surface.
