The breaking stress of a wire is dependent on

Options

  1. Athe length of the wire
  2. Bthe shape of the cross section
  3. Cthe radius of the wire
  4. Dthe material of the wire

Correct answer

D. the material of the wire

Step-by-step solution

Breaking stress is defined as the maximum force per unit area that a material can withstand before it breaks. It is an intrinsic property of the material and is independent of the physical dimensions of the wire, such as its length, radius, or the shape of its cross-section. Therefore, the breaking stress of a wire depends only on the material of the wire.
