Awoman is straining to lift a large crate, without success because it is too heavy. we denote the forces on the crate as follows: p is the upward force the woman exerts on the crate, c is the vertical contact force exerted on the crate 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?

Explanation:

Given

Force P is acting upward

C is vertical contact Force

W is the weight of the crate

As P is unable to move the Block therefore Normal reaction keeps on acting on block

thus we can say that

P-W+C=0

P=W-C

A
