Problem 4: In the figure below, block A rests on a inclined surface and is connected to a rope. The rope passes over a fixed drum B and is connected to handle CDE. A vertical force, P, is applied to the handle at point E. The weight of block A is 200 lb. Handle CDE has a uniform cross section, is supported by a frictionless hinge at D, and weighs 50 lb. The coefficient of friction, μ, at all surface is 0.3. What is the minimum force, P, for impending motion of block A up the incline? Note: All free-body diagrams must be drawn separately from the figure provided below. No credit will be given for free-body diagrams drawn on top of the figure.
