# Motor Torque

Looking for a motor to turn a large cylinder.

Say if I have a cylinder of radius 1007.54mm and mass of 2 tons, I would have a moment of innertia of 1.027x10^3 kg-m^2

This is from the general cylinder inertial equation,
I = .5*m*r^2

The torque necessary to bring this to 30 deg/ 5 min is
W= $$\varpi$$0 rad/sec + .5*$$\alpha$$*(5 min/60 sec)^2
W = 30 deg*(3.14 rad/180 deg)*2/(.00694 sec^2)

Torque is then,
