Torque Calculator

This torque calculator helps you find the torque arising in a rotating object. What exactly is this torque? Imagine an object that can rotate around some point called the pivot point. If you exert a force at some distance from the pivot point, then even though the force will act along a straight line, the object will begin to rotate.

torque Sizing a motor for a conveyor Electrical

I guess I could start with calculating the torque required: torque = force x radius. Is the radius in question that of the conveyor roll? And force = mass x acceleration. Mass = 6000lbs. Acceleration = (1800 0)/t. Assuming starting from rest and going to full rated speed. Not sure what "t" is since the motor is direct on line start (and not controlled by a VFD so there is no ramp up time) I
