Question:

The wedge is used to level the floor of a building. For the floor loading shown, determine the horizontal force P that must be applied to move the wedge forward. The coefficient of static friction between the wedge and the two surfaces of contact is μs. Neglect the size and weight of the wedge and the thickness of the beam. Units Used: kN = 103 N

Given:

F1 = 2kN a = 3 m

F2 = 4kN b = 2 m

F3 = 4kN c = 3 m

F4 = 2kN θ = 15 deg

μ s = 0.25
