Question

A machine has a velocity ratio of 5. ut requires a 50kg weight to overcome 20kg weight. calculate the efficiency of the machine ( take g= 10m/s^2)​

Answer 1

The answer is 8%

Step-by-step explanation:

We know that the efficiency of the machine is given by,

E=(M.A)*100

=(
`(20)/(50)`)*
`(1)/(5)`*100

=8%
