Mechanical+Advantage

The concepts of Simple Machines can be explained physically using models of Simple Machines and recording the forces and distances of the Effort and the Load.
==Simple Machines can also be modeled using mathematics. It involves patterns or ratios of the movements and forces between the Effort and the Load called the Mechanical Advantage. Students spend a lot of time learning mathematics, this unit allows for students to see a practical use of mathematics. These Mechanical Advantages (patterns or ratios) apply to all Simple Machines with levers used as an example below.== 8:2  or   4:1  || ==== || 10:5  or   2:1  || ==== || 8:10  or   4:5  || ==== ||
