A simple machine with an efficiency of 75% lifts a load of 5000N when a force of 500N is applied to it. Calculate the velocity ratio of the machine
The correct answer is: B
Explanation
M.A = \(\frac{load}{effort} \frac{5000N}{500N} = 10\)V.R = \(\frac{M.A \times 100}{V} = \frac{10 \times 100}{75} = 13.3\)
