1. The problem statement, all variables and given/known data
An Atwood's machine consists of two masses, m1 and m2, which are connected by a massless inelastic cord that passes over a pulley, Fig. 1070. If the pulley has radius R and moment of inertia I about its axle, determine the acceleration of the masses m1 and m2 (a), and compare to the situation in which the moment of inertia of the pulley is ignored (a0). [Hint: The tensions FT1 and FT2 are not necessarily equal.] (Use m_1 for m1, m_2 for m2, R_0 for R0, and g and I as appropriate.) a= _________ a(0)= _________ 2. Relevant equations T = I * a(angular) = F*d*sin90 3. The attempt at a solution Attempt at Solution: I was trying to sum the forces and use Torque but I have NO idea what Torque is or what the value of the normal force is. :(

never mind I found the answe online at http://tuhsphysics.ttsd.k12.or.us/Tu...S8_9/PS8_9.htm

Before you mark this as solved, does anyone know how to find the tension on each side of the pulley?
