with reference to the terms mechanical advantage, velocity ratio , efficiency of a machine , name the term that will not change for a machine of gfive design

Open in App

Solution

mechanical advantage = Input force/output force

velocity ratio = Input velocity/Output velocity

efficiency = Input energy/Output Energy

It is velocity ratio that will not change for a machine of given design while mechanical advantage and efficiency can vary according to circumstances.
