A lug wrench is used to tighten a square-head bolt. If 49-lb forces are applied to the wrench as shown, determine the magnitude Fof the equal forces exerted on the four contact points on the 1.3 in. bolt head so that their external effect on the bolt is equivalent to that of the two 49-lb forces. Assume that the forces are perpendicular to the flats of the bolt head. +1.3" 49 lb View C Detail (clearances exaggerated) 10" 49 lb 10"
