A mass of 5g is required to balance a motorcar wheel. If the mass is attached to the 0.33m diameter wheel rim, calculate the centrifugal force acting on the rim of the wheel. The speed of rotation is 521 rev/min.


ω= 2∏N/60
F= M ω2 T




ω=2∏*521/60 = 54.6 rad/s
F= 5*10-3*(54.6)2*T


I am not sure how to find T and wonder if anyone can help?

What is T supposed to be?

torque? I am confusing myself thought I thought I would find T by using T=Ia although I would need to find I first.
So am I way out? Is it just half the diameter? 0.165

Which torque?
You are told that the wheel is spinning at a constant speed, and that it is balanced.
What does that tell you about the net torque?
