This a simulation I made for my science class. Click the create object button for each side and enter the mass you want for each side. You can change the distance from the pivot (middle point) also. You can see the left and right moments change (the force going down on each side) as you change the mass and distance of the object. The moment (Ncm) is just the distance from the pivot (cm) multiplied by the mass of the object (N).
All the scripts are by me, and I made the pivot and the objects with pen :) The physics behind this was not discovered by me, you have Archimedes to thank for that :) Also note that the size of the objects can not go higher than the same size of an object of 25N because there is not enough space to fit larger objects in, and the position of objects starts at the side of the object closest to the pivot - it is not to scale.
