Ok, so a lever can be broken up into two 'sides' with a fulcrum in the middle. This idea simply utilizes the laws set forth for torque, or Force*distance. Static equilibrium (which would be when you input enough force on one side of the lever to balance the other) states the following
F1*D1 = F2*D2
Starting from the left side of the lever, for have a force (F1) multiplied by the distance between that force and the fulcrum (D1). This can be set equal to the distance between the fulcrum and the second force, with this distance denoted as D2. If you want to know the input force, you need to know the other force, and both distances. Then you can simply divide. For example say want to know your input force, F2.
F2 = (F1*D1)/D2
Hope this helps

What is The force that you exert on a lever called?
The force that you exert on a lever can be called the effort force. The lever has three parts. They are: the fulcrum, the load, and the effort force. This can also be classified as the input force. The force that you exert to perform a task is known as the input force.
In which type of lever is the direction of the input force opposite of the direction of the output force?
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
What kind of lever is a seesaw?
yes it is a 1st class lever and so is a pair of pliers!!!!
Which class of lever does not multiply input force?
The first class lever (force, fulcrum, load) doesn't change the force if the lever is symetrical. Note that if it is assymetrical, the force will change.
How is input and output shown on a force diagram?
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
How do you find the output force of a 1st class lever?
Multiply (the input force) x (the lever's mechanical advantage).
Identify the class of a lever for which does function is between the input force and the output force?
The third class lever functions between the input force and the output force
What type of lever is seesaw?
first class lever. Why? because it is in the order of output force-fulcrum-input force. output force ______________________________ input force fulcrum

If the input force is between the fulcrum and the output force what kind of lever is it?
first class lever
Can you determine the input force by knowing the input and output arm length and the output force of a lever?
Yes

Does a lever increase the effect of your input force?
yes it does
What has a pivot point between a load and an input force?
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 is input and output shown on a force diagram?
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
