1. The problem statement, all variables and given/known data Two blocks are of the same mass M. One lies on a frictionless ramp with slope θ, while the other one, connected by a rope, hangs by a pulley with a moment of inertia of I and a radius of r. Find the acceleration of the two blocks. I don't have an actual picture, but this one might help: Assuming m=M and that the pulley has a moment of inertia = I and a radius = r 2. Relevant equations F = ma Torque = Ftangential * r Tension = Mg(1-sinθ) 2Ma should (?) be the total force on the blocks. 3. The attempt at a solution I drew an FBD for the masses and got Mg(1-sinθ), but I'm unsure as to where I am supposed to go after this. I assumed that torque factored in, but I'm shaky on that aspect of the problem. The answer given was (Mg(1-sinθ))/(2M-(I/r2)).
