First of all a pair of scissors is a First Class Lever. Which means that the
Fulcrum: the pivot point, is in the middle. The Effort(which is you) is the handle of the scissor. The Resistance are the blades. HOPED THIS HELPED!:)

Why scissors are first class lever?
scissors are first class lever because they have fulcrum in between load and effort.
What is scissors type of?
It's a class one lever. If you look at the scissors the fulcrum is in the middle, effort in left side and the load on the other side.
Are scissors a first class lever?
yea because the fulcrum in that nail in the middle of this scissor and the effort, or input force, is you using the handles and the the load is the end blades of the scissor. First class is when the fulcrum is in the middle, and the load and effort are on the other sidesno
Where are the input force and output force on a pair of scissors?
The input force or the effort on a pair of scissors would be the force applied by your hands on the handles. The output force or load would be the blades of the pair of scissors.
How does a first-class lever different from a second-class lever?
In a first class lever the fulcrum is at the middle. load and effort are applied at two ends. eg scissors. In second class lever fulcrum is at one end and effort is at other end. The load is at the middle. eg nutcracker.
How does a second-class lever differ from a first class lever?
In a first class lever the fulcrum is at the middle. load and effort are applied at two ends. eg scissors. In second class lever fulcrum is at one end and effort is at other end. The load is at the middle. eg nutcracker.
Where would the load be on scissors?
on the blades
Tell you about levers and their effort and load?
The load is the weight and the effort is the movment. The effort is the force applied, and load divided by effort is mechanical advantage.
Which movements demonstrates a first-class lever?
A first class lever is when the fulcrum is inbetween the load and the effort force an example would be a seesaw or scissors. Hope this helped(:
What is first class levers?
== == There are 3 class levers, 1st, 2nd and 3rd. A 1st class lever is a lever with its Fulcrum in between the Effort and the Load. An example is the scissors and a roller coasters and glow sticks.....!!!!! (JUST REMEMBER FLE 123 1= fulcrum in the middle 2=Load in the middle 3=Effort)A Class-I lever is a lever set up like a see-saw ... with the effort andthe load located at opposite ends, and the pivot between them.Class-II and Class-III levers both have the pivot at one end.Class-II . . . the effort is at the other end, and the load is in the middle.Class-III . . . the load is at the other end, and the effort is in the middle.A see saws is the easiest description of a 1st class lever. The fulcrum is in the middle and the force is applied on one side. Scissors and pliers are other 1st class levers.Examples of first class levers are-see saw-trebuchet-scissors-spud bar-chop sticksa form of lever in which the input and output forces are on either side of the fulcrumscissors ,beam balance , seesaw,oars
Why do iron cutting scissors have short edge whereas cloth cutting scissors has long edge?
because the effort distance is longer and the effort is multiplied
Examples of first class levers?
first class levers have fulcrum at center and load and effort at extremes, examples are seesaw and scissor.
