Question

Q1. In case of pure bending of beam, neutral axis can be defined as ? (A). Bending stress is maximum (B). Bending stress is zero (C). Shear stress is maximum (D). None of the above

Answer 1

Neutral axis is the line interaction with neutral layer with transverse axis. In above neutral axis the layers are compressed and below the layers are tensed. There is no load acting on neutral axis. So bending moment on the neutral axis is zero..

so the answer is (option b) Bending stress is zero

Answer 2

Answer:

(B) zero

Explanation:

Neutral axis is the line interaction with neutral layer with transverse axis. In above neutral axis the layers are compressed and below the layers are tensed. There is no load acting on neutral axis. So bending moment on the neutral axis is zero.
