Question

A screw guage gives the following reading when used to measure the diameter of a wire.
Main scale reading : 0 mm
Circular scale reading : 52 divisions
The diameter of wire from the above data is:A. 0.52 cm
B. 0.052 cmC. 0.026 cm
D. 0.005 cm

Answer 1

Final Answer : 0.052cm

Steps :
1)
Generally, Screw Gauge has Least Count : 0.01 mm

Diemeter of screw Gauge :
=>MSR + CSR *LC
=> 0mm + 52*0.01mm
=> 0.52mm
=> 0.052cm

Therefore, Diameter of screw Gauge : 0.052cm
