Options
- AA-(S); B-(P, R); C-(Q); D-(R, S)
- BA-(P); B-(Q); C-(R); D-(S)
- CA-(S); B-(P); C-(Q, R); D-(S)
- DNone of these
Correct answer
A. A-(S); B-(P, R); C-(Q); D-(R, S)
Step-by-step solution
- A. Backlash error ( ) (S) Backlash happens due to loose fittings in the screw gauge. - B. Zero error ( ( P , R ) ) Zero error is always subtracted (P), and it may be positive or negative (R). - C. Vernier callipers ( ) (Q) Their least count is given by (1 MSD -1 VSD ). - D. Error in screw gauge ( ( R , S ) ) Screw gauge can have zero error (positive or negative ( R )) and backlash due to loose fittings ( (S )).
