Question

As the beam undergoes bending under applied loads, axial strain distribution at a point in beam

(a) axial strain is not produced

(b) remains constant

(c) varies along depth of beam

(d) varies along length of beam

This question was addressed to me in unit test.

My doubt stems from Behaviour of Real Beam topic in section Design of Beams of Design of Steel Structures

Answer 1

The correct choice is (c) varies along depth of beam

To elaborate: As the beam undergoes bending under applied loads, axial strain distribution at a point in beam varies along the depth of beam.
