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 ...
