## Problem 509 | Friction

**Problem 509**

The blocks shown in Fig. P-509 are connected by flexible, inextensible cords passing over frictionless pulleys. At A the coefficients of friction are μ_{s} = 0.30 and μ_{k} = 0.20 while at B they are μ_{s} = 0.40 and μ_{k} = 0.30. Compute the magnitude and direction of the friction force acting on each block.

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