Therr workers trying to move a 1x1x1.2-m crate apply to the cratethe three horizontal forces shown. (a) if P=240 N, replace the

threeforces with an equivalent force-couple system at A. (b)

Replace theforce-couple system of part a with a single force, and

determinewhere it should be applied to side AB. (c) determine the

magnitudeof P so that the three forces can be

replaced witha single equivalent force applied at B.
