GATE MT 2018 MT Q28: Strain tensor and stress tensor, Representation by Mohr’s circle, elasticity, stiffness and compliance tensor, Yield criteria, Plastic deformation by slip and twinning.

Determine the correctness (or otherwise) of the following Assertion [A] and the Reason [R]

Assertion [A]: Refractory BCC metals like W and Mo are less ductile than FCC metals like Ni and Pt at room temperature Reason [R]: BCC metals have fewer independent slip systems than FCC metals

Your answerChoose one option.

Both [A] and [R] are true and [R] is the correct reason for [A]

Both [A] and [R] are true, but [R] is not the correct reason for [A]

Both [A] and [R] are false

[A] is true but [R] is false
