What is a explanation about lever and wedge to make scissors?
Scissors work as both levers and wedges. The lever part of the scissors is the handle being the input force (Fin), and the blade being the output force (Fout). The middle of the scissors that only turns and moves the smallest distance is the fulcrum. The fulcrum is what make the scissors a lever by having a "jack" for the scissors to sit on while the blade does all the cutting. The way to see if the lever is efficient or inefficient, you calculate the mechanical advantage of the lever. Mechanical advantage is calculating output force (Fout) by the input force (Fin) in Newtons. In the end. since you are dividing two numbers using the same unit (Newtons) the units cancel each other out. Therefore, leaving you with a number with no units of measurement to go with the final quotient. E.G MA= Fout/Fin = 3N/1N = 3 Scissors can also be used as a wedge. You see, (a) wedge(s) is/are (an) object(s) that split(s) (an)other object(s) apart. Scissors work as a wedge because the blades push whatever you are cutting apart from each other. Finally, making a pair of scissors a wedge and a lever.

Why are scissors a lever?
Scissors are levers because, the fulcrum is between the applied force and the load. The load are the blades. Your hands are applying the force. Scissors are the first class levers. So blah blah blah!That is so not true!They are also part wedge!It is true.The question is why are scissors a lever so,this person answered that question.The question didn't ask anything about the scissors being part wedge.The question only asks about the fact that the scissors is a lever.
