Determine maximum tensile stress of the beam (Unit: MPa)

Set M = 815 N.m; b =25 mm.

Determine maximum tensile stress of the beam (Unit: MPa) Set M 815 N.m; b 25 mm. 2b Answer:

Answer 1

for hogging bending moment ,top fibre of the given cross section is subjected to tensile bending stress and bottom fibre is subjected to compressive bending stress

from bending equation
