Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
Friction between the parts of a machine decreases the work output by converting some of the input energy into heat. This results in inefficiencies and reduces the overall performance of the machine. To compensate for the energy loss due to friction, more work input is required to achieve the desired work output.
The mechanical advantage of a machine indicates how much it multiplies force or velocity. A higher mechanical advantage means the machine requires less input force to achieve a certain output force, but it may trade-off by requiring more input distance. Ultimately, the work output of a machine is affected by its mechanical advantage as it determines the efficiency in transforming input work into output work.
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.

Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine.

Output(input), or O(i)
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 efficiency
If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.
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.
