Unit D: Mechanical Systems

Unit D: Mechanical Systems. Topic 1: Levers and Inclined Planes. Lever: a simple machine that changes the amount of force you must exert in order to move an object Contains a bar that is free to rotate around a fixed point ( fulcrum ) The fulcrum supports the lever.

Simple Machines

Simple Machines. Simple Machines. Work done = Force x distance moved (in direction of the force) In this case the effort move the same distance as the load The effort force is equal to the load force (weight of load). Effort. Load. Simple Machines. Force multipliers

Levers

Levers. Definition. A simple machine A board or bar that rests on a turning point called the fulcrum Used to change the amount, the strength and the direction of movement. The position of the force and the load can be changed by moving them to different points on the lever. Definition.

Levers

Levers. M echanical Advantage. Classes of Levers. We often use machines to make jobs easier for us. Machines do this by: reducing the force we use (offering a force advantage) MA > 1 doing the job faster (offering a speed advantage) MA < 1. Mechanical Advantage.
