The force applied to a simple machine is called effort/input force.
Increase Work
A lever is a simple machine that changes the distance the force is applied over. It is helpful by since the force is applied over distance you can lift things. One example of this machine is a seesaw and a boat paddle. If we did not have this machine on a seesaw we would stay balance. Levers are devices that increase the force you use them with. Each lever has three main parts: the fulcrum, resistance arm, and effort arm.
If I'm not mistaken, there is no machine that can reduce friction. The machine is intended to change the distance the input force is applied over or to multiply the output force. The moving parts of the machine will always increase friction. In order to reduce the extra friction (but not completely remove it), one would use a lubricant or reduce the roughness between two surfaces. Hope it helps.
What is the ‘cost’ for using a machine to increase force
A fulcrum is a part of a simple machine, the lever. Without the fulcrum what is left of the simple machine can no longer increase the applied force and is no longer a simple machine.
The mechanical advantage of the machine is"if you give small accelration , it will increase the speed of the engine... It is possible by mechanical
You multiple a force time the distance over which the force is applied.
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. They can be used to increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the force.

Sailing boats are full of ingenious examples of pulleys; rowing boat oars provide one of a few examples where the fulcrum is located such that it reduces the applied force and increase the distance over which it acts
