When addressing these critical teaching ideas it is important to assist students to identify common examples of ‘simple machines’ in their world. A wedge is an object that tapers to a thin edge. Turn the bar of soap over and lay the design onto the side of the

To achieve this, the force applied must act over a longer distance or period of time resulting in the same amount of work being performed by a smaller force. high over his/her head. This effect can be reversed by applying a large force to the smaller axle resulting in a smaller force at the edge of the larger wheel with much greater rotational speed.
The force amplification, or mechanical advantage, is equal to the ratio of the two forces (W:F) and also equal to the ratio of the radii of the two gears (R:r).
