Answer:
1) 0.001mm
2) 0.297
Explanation:
i) given, pitch of the screw = 1 mm
no. of divisions on the circular reading = 100
l.c = pitch/no of division on the circular scale = 1mm/100 = 0.001mm or 0.01 mm
ii) main scale reading = 2mm= 0.2 cm
since 97th division of head scale coincides with the base line
p=97
circular scale reading = p *L.C= 97* 0.001 cm = 0.097cm
total reading= main scale + circular scale reading = 0.2cm +0.097 = 0.297cm
