Question:

The chair has a weight W and center of gravity at G. It is propped against the door as shown. If the coefficient of static friction at A is μA, determine the smallest force P that must be applied to the handle to open the door.

Given:

μA = 0.3

a = 1.20 ft

b = 0.75 ft

c = 3ft

θ = 30 deg

W = 10 lb
