(i) With reference to the terms, mechanical advantage, velocity ratio and efficiency of a machine, name the term that will not change for a machine of a given design.
(ii) Define the term stated by you in part (i).

Explanation

### Step-by-Step Solution:

**(i)** The term that will not change for a machine of a given design is **velocity ratio**.

**(ii)** The term **velocity ratio** is defined as the ratio of the velocity of effort (the distance moved by the effort) to the velocity of the load (the distance moved by the load). Mathematically, it can be expressed as:

\[
\text{Velocity Ratio (VR)} = \frac{\text{Velocity of Effort (Ve)}}{\text{Velocity of Load (Vl)}}
