Which of the following is the correct equation for bending moment (M) of an element given value of young’s modulus (E), moment of inertia (I), and radius of curvature (R)?
(a) M= EIR
(b) M= EI/R
This question was addressed to me at a job interview.
I'd like to ask this question from Shear Force & Bending Moment topic in section Beams and Frames of Finite Element Method
