A Wedge changes an input force by a change when a mechanical advantage increases as it becomes longer and thinner.
A wedge is used to take advantage of the fact that work done = force x distance.Simply put if you need to force two points apart a wedge allows you to use less force by moving a greater distance.If you knock a wedge into a piece of material by 10cms in order to widen the gap by 2cms it will take one fifth of the force to achieve this.If you think of a screw as being a nail with a very long wedge wrapped around it, you can force this into a solid piece of wood with one hand simply by taking advantage of the mechanical advantage that this wedge provides.

Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
what is force multiplier
lever
The relationship between the two is, the bigger the wedge, the less force you need and the smaller the wedge, the more force you need.

A chisel is a type of machine called a wedge. A wedge is a simple machine that consists of two inclined planes, giving it a thin end and a thick end. Force is applied to the thick end of the wedge, and the sloping sides of the wedge apply force to the object, cutting/splitting it apart. A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance. Another example of a wedge is a hammer.

The resistance force is the log. It trys to stop the wedge of the axe. The effort force of the swinging axe helps it break through the log, breaking through its resistance.

The wedge is the active twin of the inclined plane. It does useful work by moving. In contrast, the inclined plane always remains stationary. This simple machine consists of a pair of inclined planes set face-to-face, that can sustain relative sliding or rolling motion. By moving one plane relative to the other, a wedge is capable of building up enormous force in a direction perpendicular to that of the moving wedge. Force multiplication varies inversely with the size of the wedge angle; a sharp wedge ( small inclined angle ) yields a large force. With adequate friction at the interfaces, the wedge becomes a separating, holding and stopping device with countless mechanical applications.
Wedge, Squeeze, and Force. You're welcome. :P
First find the are of the 90 degree triangular end. This is 0.5*a*b where a and b are the two legs of the triangle adjacent to the right angle. Multiply the result by the length of the wedge.
