The answer is: a lever.
A lever is a simple machine that has a stick that pivots at a point called a Fulcrum.
There are 3 types of Lever:
First class lever: A first class lever is when a fulcrum is in the middle of the input force and the load. An example is a seesaw in the playground. When you press down the side of seesaw,(input force) the other side goes up. (load, output force) In the middle, there is a fixed point.
Second class lever: A second class lever is where you have the load in the middle of the Fulcrum and the input force. An example would be a wheelbarrow. The basket in the middle is the load( also called the output force) the wheel at the end is the Fulcrum, and the handle that you press up and down is the input force.
Third class lever: A third class lever is a lever that has a input force in between the Fulcrum and the Load. An example is a Hammer. The sharp part is the load(output force) the part you grab and swing is the input force, and the other end of the hammer is the Fulcrum.

How does a stapler work as a lever?
It has a pivot point
What are the 3 parts of a lever?
A Lever comprises of three components:Fulcrum or Pivot - the point about which the lever rotatesLoad or Resistance - the object that requires movingEffort - the force applied by the user of the lever system
How do you calculate the mechanical advantage of any machine?
distance over which the force is applied ________________________________ Distance over which the load was moved or MA= Effort Force _________ Load force OR MA= Length of Load arm ____________________X Weight/mass Length of Effort arm
Is a wheelbarrow second class lever?
No. It's a second class lever. A 1st class one has the pivot in the centre.
A stiff rod that rotates around a pivot point?
A stiff rod that rotates around a pivot point is called a lever. It is a type of simple machine that is used to help move a heavy or firmly fixed load.
What is the input arm and the output arm on a lever?
The input arm, also known as the effort arm, is the distance from the pivot point to where the input force is applied. The output arm, also known as the load arm, is the distance from the pivot point to where the output force is exerted.
What is the point on a lever that makes it move?
I believe you are referring to a Pivot.
What class lever is the fulcrum located between the input force and output force?
A class 1 lever has the fulcrum located between the input force and output force. This means that the force is applied on one side of the fulcrum and the load is on the other side, with the fulcrum acting as the pivot point in the middle.
How a lever can use as a force multiplier?
A lever can be used as a force multiplier by increasing the distance from the pivot point where the force is applied, which allows for a smaller input force to generate a larger output force on the other end. By adjusting the distance between the force and the pivot point, a lever can amplify the force applied to the load, making it easier to lift or move heavier objects.
What is the magnitude of the torque about the pivot point?
The magnitude of the torque about a pivot point is given by the product of the force applied and the distance from the pivot point to the line of action of the force, multiplied by the sine of the angle between the force and the lever arm. Mathematically, torque = force * distance * sin(angle).
What class lever is a pair of tongs?
A pair of tongs is considered a class 1 lever because the input force (effort) is applied between the fulcrum (pivot point) and the output force (resistance).
What are the 3 ways you can change torque?
You can change torque by adjusting the force applied, changing the distance between the force and the pivot point, or altering the angle at which the force is applied relative to the pivot point.
Why torque is zero when force is applied to point that passes through pivot point?
Torque is defined as the product of the distance from the pivot point, times a force, times an angle function. If any of the three factors is zero, the product is zero. In this case, the distance from the pivot point.
What is a part of a lever?
The fulcrum is the pivot part of a lever.
What class lever is a gate?
A gate is generally considered a class 1 lever because the pivot point (fulcrum) is located between the input force (opening/closing the gate) and the output force (movement of the gate).
How do 1 class lever make work easier?
A first-class lever makes work easier by increasing the force applied to move an object. The lever uses a pivot point, with the input force applied on one side and the output force generated on the other side. By changing the distance between the force and the pivot point, a first-class lever can amplify the force applied to the object.
What is the input distance for a lever?
The input distance for a lever is the distance from where the input force is applied to the fulcrum (pivot point). This distance determines the mechanical advantage of the lever, with longer input distances providing greater leverage.
