Question


Directions: The following items consists of two statements; one labelled as 'Assertion (A)' and the other as 'Reason (R)'.
Assertion (A): In a tension test on a cast iron specimen, the failure of the specimen is on a cross section perpendicular to the axis of the specimen.
Reason (R): The failure of the specimen is on a plane subjected to maximum tensile stress and cast iron is relatively weak in tension.

A
both A and R are true and R is the correct explanation of A

Solution

The correct option is A both A and R are true and R is the correct explanation of A
Cast iron is brittle and fails due to normal stress. It is relatively weak in tension. In a tension test maximum normal tensile stress is on cross-section perpendicular to axis of specimen, so failure will happen on this plane.
