Question

The required Velocity Ratio (V.R) for a machine whose effort distance is 3 times that of load distance is ___ .

• A. $3$
• B. $8$
• C. $\frac{1}{3}$
• D. $\frac{1}{8}$

Answer 1

The correct option is A $3$

It is given that, $Effortdistance=3\times Loaddistance$.

Plugging this value of effort distance in the formula of V.R. we get,

$V.R=\frac{Effortdistance}{Loaddistance}=\frac{3\times Loaddistance}{Loaddistance}=3$
