## Homework Statement

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. 10-70. 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)= _________

## Homework Equations

T = I * a(angular) = F*d*sin90

## 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. :(
