Question:

The winch on the truck is used to hoist the garbage bin onto the bed of the truck. If the loaded bin has weight W and center of gravity at G, determine the force in the cable needed to begin the lift. The coefficients of static friction at A and B are μΑ and μB respectively. Neglect the height of the support at A.

Units Used:

kip = 103 lb

Given:

W = 8.5 kip

μ A = 0.3

μ B = 0.2

a = 10 ft

b = 12 ft

θ = 30 deg
