A flywheel of $50cm$ outer

diameter and $10cm$ Inner

diameter is pressed onto a

solid shaft. The maximum

tangential stress induced

in the flywheel is $35$MPa.

The length of the flywheel

parallel to the shaft axis is

$5cm.$ Assuming a

coefficent of static friction

of $0\mathrm{.}2$ at the common

surface, find the maximum

tortque that may be

transmitted by the flyweel
