A pulley (in the form of a uniform disk)
with mass 79 kg and a radius 14 cm is at-
tached to the ceiling in a uniform gravita-
tional field and rotates with no friction about
its pivot. The masses are connected by a
massless inextensible cord.
Determine the acceleration of the mass
33 kg. The acceleration of gravity is 9.8 m/s2 .
Assume up is positive. Answer in units of
Net Torque = Moment of Inertia *Angular Acceleration
Torque = Force * Radius
The Attempt at a Solution
I attempted this:
I*Alpha = net toque
1/2MR^2*(A/R) = (56-33)*9.8*R
Unfortunately that didnt work...
Thanks for any help.
