Objectives This subject is designed to develop skills and understanding relating to the effect of applied loads on the design of determinate and indeterminate structures.

Synopsis Applications of strength of materials theory; strain energy of different loading systems, introduction of Castigliano's theorem, dummy loads, deflection of straight and thin curve beams. Analysis of statically indeterminate force systems by strain energy, conjugate beam techniques. Torsion of non-circular sections, membrane analogy and applications, shear centre. Composite materials, reinforced concrete and plastics. Stresses in curved beams. Close coiled helical springs; stresses, deflections. Impact loads; analysis of stresses and deflections of structures under impact loads. Properties of areas; second moment of area, principal axes. Bending stresses in beams with unsymmetrical bending moment. Analysis of thin walled vessels subject to internal pressure.
