A wooden board rests on a central triangular support underneath. Two strings hang symmetrically from above, holding a water bottle that acts as the weight. The strings pass over the triangular support and suspend the bottle below. This simple experiment illustrates force equilibrium and torque. The bottle’s weight, W = m × g, exerts a downward force, while the
