Find the power that can be transmitted.

Two pulleys, one 425mm diameter and the other 210mm diameter are one parallel shaft 2m apart and are connected by a crossed flat belt. Find the length of the belt required and the angle of conduct between the belt and each pulley. What power can be transmitted by the belt when the larger pulley rotates at 200 rev/min, if the maximum permissible tension in the belt is 1 kN, and the coefficient of friction between the belt and pulley is 0.3?

With a driveshaft turning at 2000 rpm , I then have a spring that can rotate a shaft 5000 rpm, I want this spring to assist in the drive of the driveshaft, how can I express that or calculate the effect of adding the spring would make. Including a spring system alongside a driveshaft that can assist the drive up to 5000rpm, how can I integrate the spring system to assist in the driveshaft drive, calculations on the change in rotation the spring would have of the driveshaft speed

The tensions in the tight and slack side of a belt drive system are 1850 N and 525 respectively. If the belt speed is 8 m/s what power in kW will be transmitted with no slippage

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 transmittedby 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

A fixed angle rotor exhibits a minimum radius, rmin at the top of the centrifuge tube of 3 cm and a maximum radius rmax at the bottom of the tube of 9 cm. If the rotor is operated at a speed of 12 000 rpm, what is the relative centrifugal field, RCF at the top and bottom of the centrifuge tube?
