A beam with a length of 10m has a fulcrum that rests at its midpoint. A cat that is 5m away to the right of the fulcrum has a weight of 50N. If another cat is to be placed with a mass of 6kg how far away from the left end of the beam should it be placed if the beam is to remain in equilibrium afterwards?
If a person with a mass of 65 kg sits on 3m away from a seesaw's fulcrum, what is the magnitude of the torque they apply?
If Person A with a mass of M sits on a seesaw of length L so that they are L/2 distance away from the fulcrum, what distance should Person B with a mass of m sit from the seesaw's fulcrum so that the seesaw does not rotate?
