Assertion (A): Backlash error can be minimised by turning the screw in one direction only when fine adjustment is done.
Reason (R ): Backlash error is caused due to wear and tear or loose- fittings in screws.

A

Assertion is True, Reason is True, Reason is correct explanation for Assertion.

B

Assertion is True, Reason is True, Reason is not correct explanation for Assertion.

C

Assertion is True , Reason is False.

D

Assertion is False, Reason is True.

Text Solution

Verified by Experts

The correct Answer is:
A
Both are true reason explains assertion. Since running over the defect repeatedly will cause large deviation.

This section contains Assertion (A) and Reason (R) type questions. Each question has choices (1), (2), (3) and (4), out of which only one is correct. Assertion (A) In these days, world is looking for better non-conventional energy sources. Reason (R) Due to increase in pollution caused by conventional energy resources, developing countries resources, developing countries are looking for new energy sources.

Internal micrometer is a measuring intrument used to measure internal diameter (ID) of a large cylinder bore with high accuracy. Construction is shown in figure. There is one fixed rod B (to the right in figure) and one moved rod A (to the left in figure). It is based on the particle of advancement of a screw when it is rotated in a nut with internal threads. Main scale reading can be directly seen on the hub which is fixed with respect to rod B. When the cap is rotated rod A moves in or cut depending on direction of rotation. The circular scale reading is seen by checking which division of circular scale coincide with the references line This is to be multiplied by LC to get circular scale reading. Least count = value of 1 circular scale division = ("pitch")/("number of division on circular scale") Length of rod A is chosen to match the ID(PQ) to be measured. Zero error is checked by taking reading between standard blocks fixed at normal value of ID to be measured. Zero error is positive if cap end is one the right of the main scale and negative it is on the left side. In an internal micrometer, main scale division is of 0.5 mm and there are 50 divisions in circular scale. The least count of the instrument is-
