Hi again. So, my teacher has requested that we do an explaination of how this chain works and to some how improve the method. There's the basic idea with the force acting downwards and the teeth of the chain pulling. So we could find torque to find rotational work, but would I split the circle into radians? Also, by improving it, when I graph it it's like a sin/cos graph and fluctuates up and down and what my teacher wants is how to decrease that. I know it sounds unclear but I am seriously confused myself. Any guidiance appreciated!
