Detailed explanation-1: -The efficiency of a machine is the ratio of useful energy output to total energy input-the percentage of the work input that is converted to work output. To convert efficiency to percent, you multiply by 100%. An ideal machine would have 100% efficiency.

Detailed explanation-2: -Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work). The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent.

Detailed explanation-3: -How Do You Calculate Efficiency? Efficiency can be expressed as a ratio by using the following formula: Output ÷ Input. Output, or work output, is the total amount of useful work completed without accounting for any waste and spoilage. You can also express efficiency as a percentage by multiplying the ratio by 100.

Detailed explanation-4: -Efficiency is the overall advantage the machine provides to a particular task. Output is the amount of work the machine does in Joules. Input is the amount of work put into the machine in Joules.

Detailed explanation-5: -If the machine is 60% then that means machine is capable of converting 60% work from input to output. For better understanding we take an example like we apply 100 J work as input in machine and machine efficiency is 60% then we will get only 60 J work as output.
