Name the part of the vernier callipers which is used to measure the following
Internal diameter of a mug
What do you mean by zero error of a screw gauge? How is it accounted for?
While measuring the length of a rod with a vernier callipers, below shows the position of its scales. What is the length of the rod?
When does a vernier callipers has the negative error?
Which part of vernier callipers is used to measure the external diameter of a cylinder?
A micrometre screw gauge has a negative zero error of 8 divisions. While measuring the diameter of a wire the reading on the main scale is 3 divisions and the 24th circular scale division coincides with baseline.
If the number of divisions on the main scale are 20 to a centimetre and circular scale has 50 divisions, calculate
- pitch
- observed diameter.
- least count
- corrected diameter.
Consider the following case where the zero of vernier scale and the zero of the main scale are clearly seen. If L.C. of the vernier calipers is 0.01 cm, write the zero error and zero correction of the following.
What is the zero error of a screw gauge?
