Explanation:

Theodolite is a surveying instrument used to measure horizontal and vertical angles. It consists of two graduated circles, one horizontal and one vertical, mounted on a common axis. The lower circle is called the horizontal or vernier circle, and the upper circle is called the vertical or altitude circle.

The theodolite has two clamping screws, one for the outer spindle and one for the inner spindle. The outer spindle is the one that rotates the entire instrument, while the inner spindle is the one that rotates only the telescope.

When the lower clamp screw is tightened and the upper clamp screw is loosened, the theodolite may be rotated on its inner spindle with a relative motion between the vernier and the graduated scale of lower plate.

This means that the telescope can be rotated around the vertical axis while the horizontal circle remains fixed. The relative motion between the vernier and the graduated scale of the lower plate occurs because the telescope is attached to the inner spindle, which rotates independently of the outer spindle.

This movement is useful when taking vertical angles or when sighting objects that are not in the horizontal plane. However, it is important to note that the upper clamp screw should always be tightened before taking any measurements to ensure the stability of the instrument.

In summary, when the lower clamp screw is tightened and the upper clamp screw is loosened, the theodolite may be rotated on its inner spindle with a relative motion between the vernier and the graduated scale of lower plate.
