Screw gauge is said to have a negative error.

The zero error in a Vernier callipers is said to be negative when

Draw a neat sketch of a screw gauge . Discuss the positive and negative zero errors in a screw gauge and their corrections.

A vernier calipers and a screw gauge have the same least count and zero error with the difference that the vernier calipers has positive zero error and the screw gauge has negative zero error. The number of circular scale divisions on the screw gauge is twice the number of vernier scale divisions on the vernier calipers and the pitch of the screw gauge is 1mm. If the vernier coinciding division and the circular are 3 and 97, respectively then find the number of vernier scale divisions on the vernier calipers.

The pitch of a screw gauge is 1mm and its cap is divided into 100 divisions. When this screw gauge is used to measure the diameter of a wire, then main scale reading is 2 mm and 58^(th) division of circular scale coincides with the main scale. There is no zero error in the screw gage. Then the diameter of the wire is

Diagrams show readings of a screw gauge. Figure (i) shows the zero error reading when the screw gauge is closed, figure (ii) the reading when the screw gauge is being used to measure the diameter of a ball-bearing. What is the diameter of the ball-earing ? There are 50 divisions on circular scale.

Two measure diameter of a wire a screw-gauge is used The main scale division is of 1mm In a complete rotation the screw advances by 1mm and the circular scale has 100 divisions The reading of screw-gauge is as shown in If there is no error is no error in mass measurement but error in length measurement is 1% then find max Possible error in density if diameter is 3.07 mm.

Using screw gauge the observation of the diameter of a wire are 1.324,1.326,1.334,1.336cm respectively Find the average diameter the mean error the relative error and % error .
