The Breaking Stress of a Wire Depends upon the A) Length of the Wire B) Radius of the Wire C) Material of the Wire D) Shape of the Cross-Section

Answer: C) Material of the wire  

Explanation: Stress refers to the force applied to a material divided by its area. The material of the wire, therefore, impacts the breaking stress. Therefore the correct answer is material of the wire and not radius or length or shape.
