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.
What else can I help you with?
Is a wheelbarrow a wedge or screw?
A wheelbarrow is neither a wedge nor a screw. It is a simple machine that uses the lever principle to help lift and transport heavy loads. The wheel and axle on the wheelbarrow also help to make it easier to move loads over a distance.
What is the formula of six simple machine?
Wedge- M.A= LENGTH/THICKNESS OF THE BASE Screw-M.A= CIRCUMFERENCE OF THE CIRCLE / HEIGHT OF THE SCREW Lever-M.A= LOAD/EFFORT
What Are Some Common Uses Of A Lever?
Common uses of a lever include opening a door, using a seesaw, lifting heavy objects with a crowbar, and using scissors to cut paper. Levers are simple machines that provide a mechanical advantage to make lifting or moving objects easier.
What do a crowbar nutcracker and seesaw have in common?
They are all simple machines, all have a fulcrum, all are levers, all are human powered.
What type of simple machine is the can opener?
The can opener is a compound machine, typically combining levers and gears, to make it easier to open cans by multiplying force and reducing the effort needed.

What three types of simple machines make up a pair of scissors?
Two wedges and a lever.
What other simple machines make up a wedge?
There is 6 simple machine theres screw,lever,pulley,wedge,fulcrum,inclined plane thats all
What is a linked lever system?
A link lever mechanism is a system by which a series of levers is connected to make one operation. Each lever must move in order for the operation to be complete. A printing machine is this type of mechanism.
What simple machines make up shovel?
There are four simple machines used to make the compound machine known as the lawn mower. These simple machines are the wheel and axle, the screw, the lever, and the wedge.
Are scissors simple or complex machines?
Scissors are compound machines. These scissors have fulcrum wedges and levers.wedge and a leverA scissor is a form of a simple lever.The loadforce is at the blade end - paper.The fulcrum is usually a screw,and the effort force is on the handles.scissors have more than one simple machine making it a complex machine and it has a wedge as well as a lever since it has a fulcrum to hold them togetherA pair of scissors is a combination of two wedges, acting in opposite directions, connected to a lever.A pair of scissors is a compound machine.pendulumwhat type of simple machine is scissors? there a tickle machineLeverWedgefirst class lever and wedgeTwo levers together.a scisor is a lever( first order).it has two levers on one fulcrum.a scisor is a lever( first order).it has two levers on one fulcrum.the 'machines' in scissors are simply a pivot and two closely placed blades which when brushed past one another perform a cutting manouvreThe two arms that you squeeze together are levers.The cutting edges of the scissor blades are sharpened to be wedgesFirst class machineThe lever is used in the scissor.lever screw wedge and an inclined planeit is a leverA pair of scissors consists of two levers fastened together on a fulcrum or pivot on which the levers rotate.A pair of scissors consists of two levers fastened together on a fulcrum or pivot on which the levers rotate.I have no idea, sorry.The main simple machines in use by scissors are levers. You push and pull (in a sense) on one end of each crossed lever to create the up and down motions. This creates a straight slice in the object you are cutting.Lever- fulcrum located between the input and output force. (First-Class Levers).Wedge- V-shaped object whose sides are two inclined planes sloped toward each other.I'm not that sure.. I read my science book and that's what the book says :)..
What simple machines are in a sewing machine?
A sewing machine is a compound machine. To make up a sewing machine, the simple machines you need to use are: an inclined plane, definitely a lever, lots of screws, wheels and axles, a wedge..................... you basically have to use all the simple machines!
