We denote the forces on the crate as follows: P is the upward force the woman exerts on the create. C is the vertical contact force exerted on the create by the floor, and W is the weight of the crate. How are the magnitudes of these forces related while the woman is trying unsuccessfully to lift the crate? P + C = W P + C < W P + C > W P = C
