Hello I'm working on a project which requires a rotating platform. I'm planning on turning the platform using a stepper motor, however I'm sure how to calculate the torque required to move the load. Here is what I have: the moment of inertial for the load and platform is: 2700 oz in2 the platform must turn 30 degrees in 2 seconds ( have a angular velocity of 0.2618 rad/s) the motor is directly attached to the platform (no pulleys or gears) I tried calculating the torque using the method in the pictures. The torque I got seems too large to move a load which weights 5 lb. Perhaps I should have used the step angle, or maybe the formula I used does not apply to this problem. Could someone help I would very much appropriate it. Thank you in advance.
