Show the relationship among MA, VR and n

1.	Show the relationship among MA, VR and n
Answer» Answer: The value of MA is always less than VR because: Effort decreases DUE to friction. Load is equal to effort due to no friction. Load increases due to change in speed. As VELOCITY ratio or ideal mechanical advantage is a simple ratio of TWO DISTANCES, it also does not have the unit. The friction is not involved in it. The efficiency of a simple machine is defined as the ratio of useful work done by a machine (output work) to the total work put into the machine (INPUT work).

Answer:

The value of MA is always less than VR because:

Effort decreases DUE to friction. Load is equal to effort due to no friction. Load increases due to change in speed.

As VELOCITY ratio or ideal mechanical advantage is a simple ratio of TWO DISTANCES, it also does not have the unit.

The friction is not involved in it.

The efficiency of a simple machine is defined as the ratio of useful work done by a machine (output work) to the total work put into the machine (INPUT work).
