Answer:

5%

Explanation:

Given:

Velocity ratio (V.R) = 30

Load = 300N

Effort = 200N

Efficiency of machine

[tex] = \frac{mechanical \: advantage}{velocity \: ratio} \times 100[/tex]

[tex] = \frac{ \frac{load}{effort} }{velocity \: ratio} \times 100[/tex]

[tex] = \frac{ \frac{300}{200} }{30} \times 100[/tex]

[tex] = \frac{ \frac{3}{2} }{30} \times 100[/tex]

[tex] = \frac{3}{60} \times 100[/tex]

[tex] = \frac{1}{20} \times 100[/tex]

= 5%

The efficiency of the machine = 5%
