Name the part of the vernier callipers which is used to measure the following
Internal diameter of a mug
Name the instrument which can accurately measure the following
The internal diameter of the neck of a water bottle
A vernier callipers has its main scale graduated in mm and 10 divisions on its vernier scale are equal in length to 9 mm. When the two jaws are in contact, the zero of the vernier scale is ahead of the zero of the main scale and the 3rd division of the vernier
scale coincides with a main scale division.
Find : (i) The least count and
(ii) The zero error of the vernier callipers.
(a) A vernier scale has 10 divisions. It slides over the main scale, whose pitch is 1.0 mm. If the number of divisions on the left hand of zero of the vernier scale on the main scale is 56 and the 8th vernier scale division coincides with the main scale, calculate the length in centimetres.
(b) If the above instrument has a negative error of 0.07 cm, calculate the corrected length.
What is the function of ratchet in the screw gauge?
State the formula for calculating the pitch of screw.
How do you account for negative zero error, for calculating the correct diameter of wires?
Name the measuring employed to measure the diameter of a pencil.
State whether the following statement is true or false by writing T/F against it.
The diameter of a wire can be measured more accurately by using vernier calipers than by a screw gauge.
