Question

A simple machine overcomes a resistance of ‘L’ through a distance of 0.04 m, when a effort of 500 N is applied through a distance of 0.50 m. If the efficiency of machine is 90%, answer the following question.

The velocity ratio of the machine is:

Options

• 12.00

• 12.50

• 12.25

• 11.75

Answer 1

12.50

Explanation:

\[ \text{VR} = \frac{\text{distance moved by effort}}{\text{distance moved by load}} \]

\[= \frac{0.50}{0.04} \]

= 12.50
