Question

Consider the following statements:
1. In a member subjected to uniaxial tensile force the maximum normal stress is the external load divided by the maximum cross-sectional area.
2. When the structural member is subjected to uniaxial loading, the shear stress is zero on a plane where the normal stress is maximum.
3. In a member subjected to uniaxial loading, the normal stress on the planes of maximum shear stress is less than the maximum.
Which of these statements are correct?

• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2 and 3

Answer 1

The correct option is C 2 and 3

When a member is subjected to uniaxial tensile force, the maximum normal stress is the external load divided by the minimum cross sectional area. Also, on the plane of maximum normal stress shear stress is zero.
