The bending stress at a point on the cross section caused by a moment M is equal to -
(a) M / A.
(b) M y / Z.
(c) M y / I .
(d) M E / I.
where M = bending moment, A =area, I = moment of inertia, Y= distance of the point, Z= modulus of the section and E = Young's modulus.
The correct Answer Is
(c) M y / I
(a) M / A.
(b) M y / Z.
(c) M y / I .
(d) M E / I.
where M = bending moment, A =area, I = moment of inertia, Y= distance of the point, Z= modulus of the section and E = Young's modulus.
The correct Answer Is
(c) M y / I
