With reference to the terms Mechanical Advantage, Velocity Ratio and efficiency of a machine, name and define the term that will not change for a machine of a given design.

Solution:

For a machine of a given design, due to friction and weight of the moving parts of machine, the velocity ratio does not change, but both mechanical advantage and the efficiency decreases.

Velocity Ratio : It is the ratio of the velocity of effort to the velocity of load. i.e.,

V \cdot R = \frac{V_E}{V_L}
