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%
