Find out maximum bending stress induced in beam, Mechanical Engineering

Assignment Help:

Q. A beam made of C.I. having section of 50mm external diameter and 25 mm internal diameter is supported at 2 points 4 m apart. The beam carries concentrated load of 100N at the centre of it. Find out maximum bending stress induced in beam.

This problem is case of simply supported beam with the load at its midpoint, and in this case the maximum bending moment = M = WL/4
1184_maximum bending stress1.png...(i)
Let  I = The moment of inertia = 2137_maximum bending stress2.png
1921_maximum bending stress3.png
We know that

Maximum stress at the time of Bending moment (at  y = 25mm) = M.y/I
= (100 × 103 × 25)/287621.4 = 8.69 N/mm2

The maximum bending stress = 8.69 N/mm2 .......ANS
