You must use your knowledge of torque to solve four levels of problems. This is a great challenge to find out if you understand torque. One or two forces are applied to the left side of the balance beam and you must calculate the force and / or its distance on the right side to balance the beam. You have 10 tries to solve each torque problem, choosing from four difficulty levels. Each mission is worth a different number of points. There is a high score screen to keep track of your success.
