True.
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.

A calculator and a formula for moments: Like distance from fulcrum x force = distance from fulcrum x force and I think mechanical advantage is the ratio of forces - for a lever for example where you need less force to exert a big force when for example, you wedge a crow bar in the side of the door to try and effect a break in
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.
split the wedge into a triangle and a and rectangle or square. Then calculate the surface area for each shape and add them together
It is the length of the sloped side of the wedge divided by its width.

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.

A hammer does contain a wedge element in its design. The head of the hammer has a flat surface that can act as a wedge to apply force when driving in nails.

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.
