Lever Physics

Be rest assured this is not a clash of titans; it's a fine combination of mathematics and physics. In this game, your goal is to balance the lever by putting all of the given objects onto it. At the start of each level, you will be given a lever which has labels to indicate the distances between the marked positions and the pivot of the lever. The objects and their weights are displayed at the bottom of the screen. You need to click and drag the objects onto the lever until the moments on both sides of the lever are the same, for example, if a 200g item is hanging under the 3m label on the left side, then the moment on the left is 200 x 3; and if on the right side a 300g item is hanging under the 1m label and a 100g item is hanging under the 3m label, then the moment on the right side is 300 x 1 + 100 x 3. In this case, the moments on the two sides are the same and therefore the lever will be balanced. If you have placed an item to an incorrect position, you can click and drag it back to the bottom of the screen. Note that you need to complete each level within the given time limit as shown at the top right corner, or you will lose. As you advance in the game, the number of objects will increase, and the calculation will become more complicated. Play with family and friends and see who can achieve the perfect balance!
