PART- B (16 Marks)
1. A rod of 150 cm long and diameter 2.0cm is subjected to an axial pull of 20 KN. If the modulus of elasticity of the material of the rod is 2x 105 N/mm2
Determine 1. Stress 2. Strain 3. the elongation of the rod (16)
2. The extension in a rectangular steel bar of length 400mm and thickness 10mm is found to 0.21mm .The bar tapers uniformly in width from 100mm to 50mm. If E for the bar is 2x 105 N/mm2 ,Determine the axial load on the bar (16)
3. A rod of 250 cm long and diameter 3.0cm is subjected to an axial pull of 30 KN. If the modulus of elasticity of the material of the rod is 2x 105 N/mm2 Determine 1. Stress 2. Strain 3. the elongation of the rod (16)
4. Find the young’s modulus of a rod of diameter 30mm and of length 300mm which is
subjected to a tensile load of 60 KN and the extension of the rod is equal to 0.4 mm
(16)
5. The extension in a rectangular steel bar of length 400mm and thickness 3mm is found be 0.21mm .The bar tapers uniformly in width from 20mm to 60mm E for the bar is 2x 105 N/mm2 Determine the axial load on the bar. (16)
6. The ultimate stress for a hollow steel column which carries an axial load of 2Mn is 500 N/mm2 .If the external diameter of the column is 250mm, determine the internal diameter Take the factor of safety as 4.0 (16)
