A machine has an efficiency of 61 percent. Find the input work if the output work is 140 J.
Question
Solution 1
To find the input work, we can use the formula for efficiency:
Efficiency = (Output work / Input work) * 100
Given that the efficiency is 61 percent and the output work is 140 J, we can rearrange the formula to solve for the input work:
Input work = (Output work / Efficiency) * 100
