Explain the term :
1. Pitch 
2. Least count of a screw gauge.

How they are determined?

 

(I) Pitch of screw gauge
it is the distance moved by the screw through its axis along one complete rotation.
(ii) Least count of a screw gauge - 
It is the distance moved by it in rotating the circular scale by one division.
Pitch & L.C. of the screw gauge can be determined by:
L.C = Pitch of the screw gauge ÷
 total number of divisions on its circular scale


For example, it a screw moved by
 1 mm through 1 rotation and id the circular scale has 
100 divisions, then the pitch of the screw = 1 mm.
The L.C = 1 mm/100 = 0.01 mm = 0.001 cm

Dear student,

(i) Pitch of a screw gauge - 
it is the distance moved by the screw through its axis along one complete rotation.
(ii) Least count of a screw gauge - 

It is the distance moved by it in rotating the circular scale by one division.
Pitch & L.C. of the screw gauge can be determined by:
L.C = Pitch of the screw gauge 
÷

 total number of divisions on its circular scale
For example, it a screw moved by

 1 mm through 1 rotation and id the circular scale has 
100 divisions, then the pitch of the screw = 1 mm.
The L.C = 1 mm/100 = 0.01 mm = 0.001 cm
