What will be the ME of a machine that produces a 240 N work with a 300 N work input?

Given:
Solution:

Efficiency = 80%

Explanation:

Given the following data;

Work output = 240 N

Work Input = 300 N

To find the mechanical efficiency of a machine;

Substituting into the equation, we have;

Efficiency = 80%

Therefore, the mechanical efficiency of the machine is 80 percent.
