The force applied when using a simple machine is typically referred to as input force. The input force is the force that is used to operate the machine and is usually applied through a lever, pulley, or other mechanism to overcome resistance (output force) and perform work. The ratio of the output force to the input force is known as the mechanical advantage of the machine.
This simple machine is likely a lever, where the load is on one end and the applied force is on the other. By using a lever, you can lift a load that is double the weight of the force applied due to the mechanical advantage gained.
The input force is proportionally smaller than the output force. If you put more force into the machine than you get out, that makes the job harder. That defeats the purpose of using the machine at all.
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.
2 forces are always involved when using a machine. * Effort Force - FE - the force applied to a machine. * Resistance Force - FR -the force applied by a machine.
A lever is a simple machine that can change the amount of force exerted by using a pivot point to either increase or decrease the force applied.
the work a machine does is the work output what it takes to do the work is the work input
When using a simple machine, the force you must overcome is usually the resistance force, which is the load or weight you are trying to move. Simple machines, such as levers, pulleys, and inclined planes, are designed to multiply the effort force applied, making it easier to lift or move heavy objects. By increasing the mechanical advantage, these machines allow you to exert less effort while still overcoming the resistance force.

The two forces involved in using a machine are the input force, which is the force applied to the machine, and the output force, which is the force exerted by the machine to do work. The relationship between these forces determines the machine's mechanical advantage.
What is the ‘cost’ for using a machine to increase force
A driver uses a simple machine like a wheel and axle to increase the force applied to turn the steering wheel, making it easier to navigate the vehicle. Additionally, the gear shift lever in a car is another example of a simple machine that allows the driver to change the direction or magnitude of the force needed to shift gears.
