Answer to Question #173402 in Mechanical Engineering for Macdonald

Question

An electric motor with a 100mm diameter pulled revolves at 100 rev./min. The motor drives a line shaft by means of a flat belt, calculate the speed of the belt in meters per second. (314m/min)

Answer 1

The diameter of pulley(d)=100 mm=0.100 m

Rotational speed(N)=100 rpm

The speed of belt passing over the pulley (Linear speed) is given as,

V=$\frac{\pi ×d×N}{60}=\frac{3.14×0.100×100}{60}=0.5233$ meters/seconds =0.5233×60=31.4 meters/minutes
