Great, so something along the lines of torque = I * α torque = r x F → Force = torque / r ? I really appreciate all of your help. Thanks a bunch

Lets see. So, the angular acceleration is equal to α = dω / dt So, α = (-607.375 rad / sec) / 0.005 sec → α = -121475 rad / sec^2 Alright, so now I've calculated both the angular acceleration. Any other hints to getting me closer to finishing this one up? It's been a while since I took a...

Homework Statement Essentially, I am trying to determine the force that must be applied to a rotating disc to that stop that disc from rotating in a certain time period. The disc is rotating at 5800 rpm, the disc has a radius of 5 inches, and a thickness of 0.087 inches. The disk is made...
