Wedge

toc

Introduction:
Wedges offer another example of a force distance tradeoff. Unfortunately, their use is limited because of the friction they usually create.

Activity:
Try the wedge sample provided by your teacher. Explain the force-distance trade-off involved.

The Essence of The Wedge:

 * A forward force produces a sideways force.
 * Push down on the axe, and the wood splits sideways.
 * Push forward on the door wedge, and the door gets squeezed upwards.
 * MA = (Forward Length) / (Sideways Length)
