Do levers always act alone, or do they act with other machines? Give an example of a lever working with another simple machine
Lever and any other simple machine can work with other machines. For example, a paper cutter is a lever with the fulcrum at one end. But the blade of the paper cutter is another simple machine - a wedge. The two simple machines work together to cut paper. A hedge clipper is made up of two levers. Each has its fulcrum between the two ends. And just an in the paper cutter, the blades are wedges.
