speed fluctuations

Repeat Problem 1.61 except change the punch force to 10,000 N, stroke to 50 mm, and drive shaft speed to 900 rpm.

 

Problem 1.61

A punch press with flywheel adequate to minimize speed fluctuations produces 120 punching strokes per minute, each providing an average force of 2000 N over a stroke of 50 mm. The press is driven through a gear reducer by a shaft rotating 300 rpm. Overall efficiency is 80%.

(a) What power (W) is transmitted through the shaft?

(b) What average torque is applied to the shaft?
