Homework Statement
Answer: C
Note: Sorry admins for the picture, needed to include the diagram though.
Homework Equations
∑[itex]\tau[/itex] = I[itex]\alpha[/itex]
∑F = ma
a = [itex]\alpha[/itex]r
The Attempt at a Solution
The torques must be balanced (is this reasoning already wrong?), thus,
F*R1 = F_T*R2
F_T = FR1/R2
The only force acting on the block is the F_T, thus the acceleration is FR1/mR2
Why are the torques not balanced in this case? If not, how do I exactly relate the moment of inertia of the entire disk to fit into the entire problem? Thank you in advance for the help!
