Q1:

Pick up the correct statement from the following:

A For steel castings, the minimum tensile strength is 41 kg/mm2 and minimum yield stress is 20.5 kg/mm2

B
For mild steel the minimum tensile strength is 44 kg/mm2 and minimum elongation of 23% on a gauge length of 5.65A

C For high tensile steel, the minimum tensile strength is 58 kg/mm2

D All the above.

ANS:D - All the above.

Mild steel 44kg/mm2? It might be 24.
