A leather belt is required to transmit 7kw from a pulley one metre in diameter running at 300 rpm. The angle embraced is 160° and coefficient of friction between the bel and the pulley is 0.3. If the safe working stress for the leather belt is 1.5 Mpe density of leather is 1 x 10 g/m and thickness of belt is 10mm, determine the widn of the belt taking centrifugal tension into account.

A leather belt is required to transmit 7kw from a pulley one metre in diameter running
at 300 rpm. The angle embraced is 160° and coefficient of friction between the belt
and the pulley is 0.3. If the safe working stress for the leather belt is 1.5 Mpa,
density of leather is 1 x 106 g/m and thickness of belt is 10mm, determine the width
of the belt taking centrifugal tension into account.
