Homework Statement
If we only know the force Fr, Find the angular velocity of the flywheel.
Homework Equations
The Attempt at a Solution
in the pulleys
F=F1=F2=F3
Fr=(F Sin β)/sin (β/2)=2F cos (β/2)
F = (2 cos (β/2))/Fr
so now for the flywheel
I=1/2 MR2 ..... M=mass R=Radius
τ=RF and τ=Iα .... τ = torque α = angular acceleration
so
α = 2F / MR
could you tell me if I'm right ?? and how can I can find the angular velocity.??
thank so much for your help
