What is the efficiency of a machine that has work input of 40 joules and work output of 35 joules

Respuesta :

In order to find that there is a formula that can be used to find it.

Work Efficiency = Work Output/Work Input x 100%
Work Efficiency = 35/40 x 100%
Work Efficiency = 87.5%

Therefore the work efficiency of the machine is 87.5%

The efficiency of the machine is 87.5%.

What is efficiency?

This can be defined as the ratio of the work output to the work input of a machine, expressed in percentage.

To calculate the efficiency of the machine we use the formula below.

Formula:

  • E(%) = (Wo/Wi)100........... Equation 1

Where:

  • E(%) = Efficiency of the machine
  • Wo = Work output
  • Wi = Work input.

From the question,

Given:

  • Wo = 35 Joules
  • Wi = 40 Joules

Substitute these values into equation 1

  • E(%) = (35/40)100
  • E(%) = 87.5 %

Hence, the efficiency of the machine is 87.5%.
