Question

If a machin

has a mechanical advantage of 4, and an ideal mechanical advantage of 5. What is the
efficiency of the machine?

Answer 1

Efficiency = 80%

Step-by-step explanation:

Given the following data;

Mechanical advantage (MA) = 4

Ideal mechanical advantage (IMA) = 5

To find the efficiency of the machine;

Mathematically, the efficiency of a machine is given by the formula;

`Efficiency = \frac {MA}{IMA} * 100`

Substituting into the formula, we have;

`Efficiency = \frac {4}{5} * 100`

`Efficiency = 0.8 * 100`

Efficiency = 80%
