Unformatted text preview: Code No: NR10802 NR I B.Tech Supplementary Examinations, June 2005 STRENGTH OF MATERIALS (Chemical Engineering) Time: 3 hours Max Marks: 80 Answer any FIVE Questions All Questions carry equal marks star star star star star 1. (a) Explain the typical stress-strain curve with a neat sketch, obtained from a direct tension test on a mild steel rod and explain the salient points. (b) A 500 mm diameter circular reinforced concrete column is having 8 bars of 20 mm diameter. The column is subjected to an axial thrust of 875 kN. Determine the stresses developed in concrete and steel. Assume E steel = 12 E concrete . 2. (a) Define the terms young’s modulus, shear modulus, Bulk modulus and Poisson’s ratio. (b) A bar of certain material 60mm × 60mm in cross-section is subjected to an axial pull of 180 kN. The extension over a length of 100mm is 0.05mm and decrease in each side is 0.00525mm. Calculate modulus of Elasticity, Poisson’s ratio, Rigidity Modulus and Bulk modulus....
