A horizontal beam in a kinetic sculpture is balanced on a pivot. A metal sphere hangs from the beam to the left of the pivot and a second sphere hangs at a fixed position to the right. The weight of the beam acts through the pivot. The sphere on the left is then moved slowly further away from the pivot.
Explain the effect on the beam.
