Question

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

N work input?

Given:
Solution:
Answer:

Answer 1

Efficiency = 80%

Step-by-step explanation:

Given the following data;

Work output = 240 N

Work Input = 300 N

To find the mechanical efficiency of a machine;

`Efficiency = \frac {Out-put \; work}{In-put \; work} * 100`

Substituting into the equation, we have;

`Efficiency = \frac {240}{300} * 100`

`Efficiency = 0.8 * 100`

Efficiency = 80%

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