WHAT ARE SCISSORS?
A pair of scissors uses a combined mechanism known as a compound machine. Compound machines are comprised of two or more simple machines in an effort to more efficiently exert force, like the cutting of an object.
The blades of the scissors are a pair of wedges in a cross shape which pivot around a fulcrum. The attached handles are levers.
When force is applied to the handles, it causes the bladed wedges to come together to cut an object from both sides.
