Whether large or small, human, mechanical, or natural, all systems consist of many components that can be studied and improved. Students will learn to calculate the mechanical advantage of mechanical systems, and will learn about the overall safety, efficiency, and effectiveness of a variety of systems.

Input Force (Force is measured in Newtons) Efficiency = Mechanical Advantage x 100%. Speed Ratio. Work = Force x Distance (W = F x d ) (Work is used to calculate both input work and output work) Work Efficiency
Mechanical systems. A mechanical system is one which is based on mechanical principles and the different parts interact in a mechanism. A mechanical system usually involves movement of some kind. It is often a group of simple machines working together. Do you remember the elastic bands pushing the matchboxes? Do you think that was a system? You ...
