Statement of a problem № 41661


The bolts on the cylinder head of an engine require tightening to a torque of 88m 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 in diameter, estimate the force applied near each of the six points by a socket wrench (Fig. 8-41).
