Concepts Of Physics MCQ Edition [Volume 1]PhysicsSome Mechanical Properties of Matter
The breaking stress of a wire is dependent on
Options
- Athe length of the wire
- Bthe shape of the cross section
- Cthe radius of the wire
- 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.
