Question

A certain machine has an efficiency of 48 % the velocity ratio of the machine is is 20 , the lift a load of 2 KN using this machine , find the following values1) mechanical advantages (M.A​

Answer 1

Given:-

Efficiency of machine, $\eta=0.48$

velocity ratio=20

Load=2 kN

To Find:-

Mechanical Advantage

Step-by-step explanation:-

$\text{There is a direct relation between MA and efficiency of machine and is given by:-}\\\\MA=\text{velocity ratio}\times\eta\\\Rightarrow MA=20\times0.48=9.6$
