Question

The breaking stress of wire depends on ________.

• A. material of the wire
• B. length of the wire
• C. radius of the wire
• D. shape of the cross-section of the wire

Answer 1

The correct option is A material of the wire

Breaking stress is the maximum normal stress that can be applied on the material, before the material breaks.

Breaking stress or elastic limit of a wire is a property of its material and not its dimensions.

So option A is correct.
