14.a What is strain energy? Derive expression for strain energy developed in rod (4)
subjected to axial loading only.
‏حا‎ A thick cylinder of internal diameter 400mm and external diameter 600 mmis (10)
subjected to an external pressure of 4 MPa.
i) Sketch variation of radial pressure across the thickness of the wall.
ii) Sketch variation of hoop stress across the thickness of the wall.
iii) Find the internal pressure that can be applied for a limiting hoop stress
of 15 MPa.
Module 3
15 A horizontal beam ABCD has a total length of 10m and carries uniformly (14)
distributed load of 0.18kN/m over the entire length of the beam. The beam also
carries a concentrated load of 0.210 at the left end A. The beam is supported on
two points (B & C) 7m apart such that each support carries the total load
equally. Calculate:
i) The length of the overhanging portions AB & CD.

ii) Draw the Shear force diagram and Bending moment diagram.
