A flat belt type is used for a belt drive system connecting two pulleys 1.2m apart. The driver pulley with diameter 40 cm is rotating with the speed 350 rpm, while diameter of driven pulley is 100 cm. Coefficient of friction of the contact surface between belt and pulley is 0.3. Maximum allowable tension is 600N. (i) Find the power transmitted by the belt, P. (ii) Determine the Initial tension of the belt, TA. iii) If the flat belt is now replaced by a Vee-belt with groove angle of B = 300 , find the power transmitted by this belt. Give explanation why power transmitted by flat andVee-belt type are not the same. Explain your answer according to basic friction concept. iv) If a Vee-belt with groove angle of B = 900 is being used, find the power transmitted by this belt. Discuss your findings by comparing with answer in (i) and answer in (iii) above. (v) List and explain TWO (2) practical applications each for flat belt and Vee-belt drive
