As per bending formula:
Where
M = bending moment due to load, σ = bending stress, E = Modulus of Elasticity, R = radius of Curvature, y = distance of outer fibre from the neutral axis
I is the MOI about a neutral axis and it is given as:
Calculation:
Given:
E = 2 × 105 N/mm2, R = 8 m = 8 × 103 mm, A = 80 mm × 15 mm, y = 15/2 mm
