Hey,
So I am not sure if this is in the right section but feel free to move it.
We are conducting an experiment at school at the moment and are having difficulty understanding all the theory and principles as to why these things are happening. However the greatest difficulty we are having so far is determining a way to calculate the theoretical torque for our experiment. Ill post a photo below to help but I was just wondering if there is a way to calculate the torque required for the lever with a force sensor on the left hand side to pull the spinning disc that is attached to a dc motor with varying voltages, out of its axis.

The variables we have identified that we know are the diameter of the disc, its weight and the rpm that it is spinning at, we also know the length of rod connecting the motor and disc to the horizontal bar at the top, the length of the horizontal bar and the length of the lever we are pulling.
Also the disc is spun by a motor and then the wooden block that houses the motor and spin left and right 360 degrees which then the horizontal rod can move to act like a pendulum movement.
So the main thing we are struggling with is determining an equation of some sort we can use to get an approximate theoretical torque required to pull the disc out of its axis that we can compare to what data we actually get.
Any idea, thought or improvement is greatly appreciated
