Question
A flat belt, of density 1000 kg/m3 has a maximum permissible stress of 2·5 MN/m². The
belt is 200 mm wide and 12 mm thick.
(a) Determine the maximum power that can be transmitted if the ratio of tight-side to
slack-side tension is 2. 
The diameter of the driving pulley is 900 mm and the required speed of the output shaft is
955 rev/min
(b) Taking the belt thickness into account, determine the required diameter of the
output pulley. 
(c) What would the required diameter be, assuming a total slip of 4%? 
(d) If the mass of the belt was neglected, explain the effect (with reasons) this would
have on the maximum power calculated in (a)
