How you calculate the input force that you apply to bike pedals involves multiplying the force by the distance the object moves in the direction of the force. This is a part of the law of the lever.
The catapult is a simple machine. The work input is the restraining of the payload and pressure put on the spring or lever. The work output is the delivery of the payload with the energy of the work transferred to it.
let the input force be F1,and the distance between point of application of input force and the lever point is x1,similarly if output force iis F2,and distance of it's point of apllication is x2,then efficiency of the lever is (F2*x2)/(F1*x1) actually F*x gives the work done,and efficiency of any machine is output work/input work
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
yes it is a 1st class lever and so is a pair of pliers!!!!
how do I calculate the input work of an inclined plane

How you calculate the input force you apply to bike pedals involves the use of the law of the lever. In this case, the force must be multiplied by the distance that the object moves in the direction of the force.

Someone pushing against a lever.
because if there wasn't an input force, or any one of those, the machine would not work properly
a fulcrum.
With a third class lever, the input force is located between the fulcrum and the load. They increase the distace the load is carried.
A Lever
Work output divided by Work input Times 100
From the design of the lever (on paper), the mechanical advantage is effort arm/load arm which means Distance from pivot to the applied force/distance from pivot to the load The result of that is that the forces will have the reciprocal ratio, and the input force to the lever will be the output force/the Mechanical Advantage .
You can push or pull in the same direction
