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)
