Explain the use of screw gauge and vernier caliper in measuring smaller distances.
Answers
Vernier calipers and screw gauge both have sub-scale so it helps to maintain high precision &accuracy.
⇒Screw Gauge Uses- It is used to measure
(i)Diameter of the wire
(ii)Thickness of the metal sheet or paper.
Least Count ( 0.0001 cm) , Screw gauge is Accurate upto third decimal of cm
It has two types of scale – one is main and other is secondary scales. The secondary scale is used to measure a pitch of the screw and the scale is divided into 50 equal parts and measures 100th of a mm.
⇒Vernier calipers uses :- It is used to measure :-
(i) The length of the rod.
(ii) Diameter of the sphere
(iii) Diameter of hollow cylinder.
Least count of Vernier caliper is 0.01 cm.
It consist long & thin steel strips . Scale is graduated for one division = 1mm.
Hope it Helps. :-)
