Question:
In ten rotation of the screw,distance traveled on main scale is 20 mm. If number of divisions on circular scale are 50. Find L.C. of micrometer screw gauge.
Answer:
Distance traveled in 10 rotations = 20 mm
Distance traveled in 1 rotation(Pitch) = 20/10 mm = 2 mm
Number of divisions on circular scale = 50
Least Count of the screw = Pitch/Number of divisions
L.C. = 2/50 = 1/25 = 0.04 mm
Thanking You!
