Engine pulley

The engine has a 1460 rev/min (RPM). The disc diameter is 350 mm. What will be the peripheral disc speed in RPM? Pulleys on the engine have a diameter of 80mm, and a disc has a diameter of 160mm.

Correct answer:

n2 =  730 1/min
n3 =  13.3779 m/s

Step-by-step explanation:

D1=80 mm D2=160 mm  n2=1460 D1/D2=1460 80/160=730 1/min
D3=350 mm m=350:1000  m=0.35 m n3=π D3 n2/60=3.1416 0.35 730/60=13.3779 m/s
