Efficiency
If the input work equals the output work, the machine has 100% efficiency, meaning it is able to convert all the input work into useful output work without any losses. An efficient machine is desirable as it maximizes the output for a given input.
mechanical advantage
If a machine's input work and output work are equal, the machine has high efficiency. This means that the machine is able to convert a high percentage of the input work into useful output work without significant energy losses.
A fax machine is considered both an input and output device. It receives data as input (the document being faxed) and sends the data as output to another fax machine.
To calculate input force, divide the output force by the mechanical advantage of the machine or system. Input force = Output force / Mechanical advantage. The output force is the force exerted by the machine, while the input force is the force applied to the machine.

Output(input), or O(i)
If a machine's input work and output work are equal, the machine has high efficiency. This means that the machine is able to convert a high percentage of the input work into useful output work without significant energy losses.
A fax machine is considered both an input and output device. It receives data as input (the document being faxed) and sends the data as output to another fax machine.
Output is always greater than input. The output is multiplied from input.
To calculate input force, divide the output force by the mechanical advantage of the machine or system. Input force = Output force / Mechanical advantage. The output force is the force exerted by the machine, while the input force is the force applied to the machine.
The input force is the force applied to a machine to make it work, while the output force is the force produced by the machine as a result of the input force. In simple terms, the input force is what you put into a machine, and the output force is what you get out of it.
Input force is the force applied to an object, while output force is the force exerted by the object in response. In a simple machine, the input force is the force applied to it, and the output force is the force produced by the machine to do work. The relationship between input and output forces determines the efficiency of a machine.
In a compound machine, the input force is applied to the first machine and then becomes the output force for the next machine in the sequence. The output force of the first machine becomes the input force for the next machine, and so on. Therefore, the input and output forces of the parts of a compound machine are related as they are transferred from one machine to the next within the system.
In a closed system in the "real world" in which we live, there are losses associated with friction and other actions. These forces "take energy" from the system between its input and output. When we apply force to the imput of a system, some is lost as the force is transferred through that system. That means that the output force we observe will always be a bit less than the input force. A transmission in a vehicle is a classic example of the idea that there are losses between the input and the output of a system. The input from the engine will always be a bit greater than the output at the tailshaft (or axles for a transaxle) due to losses within the transmission.
