[QUOTE="LCSphysicist, post: 6345245, member: 675151"] [B]Homework Statement:[/B] I am trying to solve a problem by torques and conversation of energy, but the answers don't match. [B]Relevant Equations:[/B] t = rf E = constant [B][ATTACH type="full" alt="1590165238935.png"]263271[/ATTACH][/B] By third Newton's law, i would imagine that fa = -fb, so and assuming f to be the average value torque in A -ra*f*t = Waf - Wao torque in b rb*f*t = Wbf and Ia*wo² = Ib*wbf² + Ia*waf² it Looks right to you? I really appreciate this method that i thought, but the answers don't match, and i don't know what is wrong. THe justification to use the conservation of mechanic would be: The work done by one force will be equal to the work done by the reaction force, but opposite in signal, so it cancel. [/QUOTE]
