The bolts on the cylinder head of an engine
require tightening to a torque of 75 m •N. If a wrench is 28 cm long, what
force perpendicular to the wrench must the mechanic exert at its end? If the
six sided bolt head is 15 mm across (Fig. 10-49), estimate the force applied
near each of the six points by a socket wrench.
