Question

the value of velocity ratio is greater than the value of mechanical advantage​

Answer 1

The mechanical advantage of a machine is always less than its velocity ratio.It is because mechanical advantage decreases due to the friction and weight of moving parts of the machine, but the velocity ratio remains constant.

Answer 2

Answer:

hii follow me

Explanation:

The mechanical advantage of a machine is always less than its velocity ratio.It is because mechanical advantage decreases due to the friction and weight of moving parts of the machine, but the velocity ratio remains constant. Similarly, if mechanical advantage had been equal to the velocity ratio of the machine then the efficiency would have been 100%, which is impossible.
