Q3) A lug wrench is used to tighten a square-head bolt. If 50-lb forces are applied to the
wrench as shown, determine the magnitude F of the equal forces exerted on the four contact
points on the 1-in. bolt head so that their external effect on the bolt is equivalent to that of the
two 50-lb forces. Assume that the forces are perpendicular to the flats of the bolt head.
