mechanical advantage
refers to the number of times a machine multiplies force
mechanical advantage

force applied to the machine
consist of a rigid bar that is free to pivot on a fulcrum
lever
consist of a slope surface, which has some angle above or below the horizontal used to raise objects that are too heavy to life vertically
inclined plane
along incline wrapped around a shaft, so its mechanical advantage can be approached in the same way as the incline
screw
embodies the same principles as the incline in the sense that, a smaller force working over a longer distance can produce a longer force acting through a small distance
wedge
consist of a wheel that rotates around a stationary scale
pulley
wheel attached rigidly upon an axle or drum of smaller diameter
wheel and axle
