Mechanical systems. Diagram of six different mechanical systems,with arrows showing the direction of the forces involved. At upper left is a lever pivoting around a fulcrum,with a weight at one end. At upper centre is a single fixed pulley,with a rope wrapped around a wheel being used to raise a weight. At upper right is a compound set of multiple pulleys (block and tackle) where the load is distributed between the pulleys and sections of the rope. At lower left is a weight being pulled along an inclined plane,rather than being lifted directly up. At lower centre is a wedge being used to split a piece of wood. At lower right is a screw | |
