Question

Q1. Bending equation of beam is ? (A). M/l=E/R (B). I/M=E/R (C). M/I=R/E (D). M/R=E/I

Answer 1

The answer of your question is M/I=E/R

Answer 2

Answer:

(A)

Explanation:

BENDING EQUATIONS FOR BEAMS-

M/I = σ/y = E/R

Where, M= bending moment,

  I=Moment of inertia of the area of cross section.

 σ=Bending stress

 y=distance of extreme fibre from the neutral axis

E=Young’s modulus

 R=radius of curvature.

From the bending equation   M/I = σ/y

         Or, M = σI/y = σ Z, where Z is the section modulus

Hope it help you my friend!!!
