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.
