...pressing down at the end 6, the other end of the lever raises the weight ; the centre of motion is at a, the fulcrum. In other words, the power or force resting on the prop or fulcrum overcomes the weight or re- , sistance. It is the property of the lever that the power increases in &' direct proportion with...
