Question

A simple machine displaces a load of 125 kgf through a distance of 0.30 m, when an effort of 12.5 kgf acts through a distance of 4.0 m. Answer the following question.

The mechanical advantage of the machine is:

Options

• 9

• 10

• 12

• 8

Answer 1

10

Explanation:

$$\mathrm{MA} = \frac{L}{E}$$

$$ = \frac{125\ \mathrm{kgf}}{12.5\ \mathrm{kgf}}$$

= 10
