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.

What precautions should you take to prevent injuries when dealing with heavy loads?
