Belt Drive

  • #1
Wheel A of radius ra = 14.6 cm is coupled by belt B to wheel C of radius rc = 28.8 cm. Wheel A increases its angular speed from rest at time t = 0 s at a uniform rate of 7.1 rad/s2. At what time will wheel C reach a rotational speed of 240.7 rev/min, assuming the belt does not slip?

I did ...Vta = Vtc, but stil didint get it. i got the Vtc
value and divided that by raduis of A to get w for a. then
divided the acceleration by the w for a, but my time is
still wrong!!

Sounds like you are basically using the correct approach. Can you please post your calculations (including units) so we can see if it's just a math error?
