While measuring diameter of wire using screw gauge the following readings were noted. Main scale reading is 1 ~mm and circular scale reading is equal to 42 divisions. Pitch of screw gauge is 1 ~mm and it has 100 divisions on circular scale.

Question

While measuring diameter of wire using screw gauge the following readings were noted. Main scale reading is 1 ~mm and circular scale reading is equal to 42 divisions. Pitch of screw gauge is 1 ~mm and it has 100 divisions on circular scale. The diameter of the wire is x 50 ~mm . The value of x is :

Correct answer: C. 71

aligned & MSR =1 ~mm , CSR =42, pitch =1 ~mm & LC = pitch No. of CSD = ( 1 100 )=0.01 ~mm & Diameter = MSR + LC CSD & Diameter =1+(0.01) 42 ~mm & Diameter =1.42 ~mm = x 50 & x =71 aligned
