Question

If a machine overcomes a load $L$ and the distance travelled by the load is $25m$. Similarly, the effort applied in the machine is $E$ and the distance travelled by effort is $75m$, and ${}^{\prime }{T}^{\prime }$ is the time taken,then velocity ratio is:

• A. $\frac{1}{3}$
• B. $\frac{2}{3}$
• C. $\frac{3}{1}$
• D. $1$

Answer 1

Answer: (A)

$\frac{1}{3}$

The VR is define as ratio of distance travelled by effort:distance travelled by load

$VR=\frac{E{}_d}{L{}_d}$

$VR=\frac{25}{75}$

$VR=\frac{1}{3}$

option A is correct.
