Question

Calculate the section modulus of the beam shown below if P-a62N it the allowable rormal stressors = 150 M Pa and in iomleves

Answer 1

Answer #1

load is assumed to be point load P =62 KN at the centre

now this is reduced to case of simply supported beam with point load at centre

now Maximum Bending moment = P*length of neam/4 = 62*4/4 = 62 KNm

now maximum allowable bending stress = Max moment /Section modulus

150*10⁶ = 62*10³/Section modulus

Section modulus = 4.13333 * 10^-4 m³ = 413.333 mm³ Ans
