Question

Consider the following statement(s) for its correctness.
A. At neutral axis there is no stress of any kind.
B. Neutral axis of a section always passes through its centroid.
C. Moment of any area about an axis passing through its centroid is equal to zero.
D. According to theory of simple bending, all layers above the neutral axis are subjected to compression.
E. In case of symmetrical section like square, rectangle and circle the neutral axis passes through geometric centre.
Choose the correct answer from the options given below:

• A. A and C only
• B. B and D only
• C. B, C and E only
• D. A, B, C, D and E

Hint:

Remember that in real beams, bending is often accompanied by shear.
While bending stress is zero at the neutral axis, shear stress reaches its maximum value at this axis.

Answer 1
