Efficiency
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.
Input force is the force you put in to a machine. Output force is a force exerted by a machine.
The work done by a machine is called work output
the input force is how much energy or force you put into the machine, the output force is how much energy the machine produces with the end product.
Input force is the force you put in to a machine. Output force is a force exerted by a machine. You exert input force on the wheel and when the axle rotates it exert large output force.
Mechanical Advantage
Output(input), or O(i)
Output is always greater than input. The output is multiplied from input.

Input force is the force you put in to a machine. Output force is a force exerted by a machine.
The difference between and input force and an output force is that an output force is force exerted by a machine, and an input force is force exerted on a machine.
An input force is what force you act upon a machine. The output is what it does for you in return.
Work Output is the work done BY a machine. Work Input is the work done ON a machine.

The work done by a machine is called work output
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
