[QUOTE="haven, post: 6825556, member: 730788"] [B]Homework Statement:[/B] The 7.80 kg spool has a radius of gyration of 0.320 m and rolls without the ropes slipping. The ropes have negligible mass. There is also a force pulling the spool upward at 100N and the outer radius is 0.5 and the inner radius is 0.2-shown in picture Let up be the positive y-direction and CCW be the positive rotational direction. Assume 3 SF for all givens. [B]Relevant Equations:[/B] Torque = I*a Io=m*ro^2 What I did was plug in the outer radius time the force into the torque and then the mass moment of inertia is equal to m*ro^2 so then I plugged in the mass times the radius of gyration squared into I and solved for a but this is not right.
