Part–A
(10 X 2 = 20 Marks)
1. A bar of varying crosssection consists of two sections of lengths l1 and l2 with cross sections
A1 and A2 respectively. It is subjected to an axial pull F . Find the total elongation.
2. The Young‘s modulus of a material is 200kN/mm2 and its rigidity modulus is 80kN/mm2 .
Determine its bulk modulus.
3. What is point of contraflexure? In which beam will it occur?
4. Derive the relation between the intensity of load and shear force, in bending theory.
5. Draw the shear stress distribution diagram for an Isection.
6. Derive an expression for the power transmitted by a circular shaft in S.I. units, which is subjected to a torque T in N m.
7. Distinguish between close coil and open coil helical springs.
8. Derive an expression for the longitudinal stress in a thin cylinder subjected to an uniform internal fluid pressure.
9. What is the normal stress on an inclined plane in a block when it is subjected to two mutually perpendicular normal stresses and shear stress?
10. State the condition for the use of Macaulays method.
Part-B
(5 X 16 = 80 Marks)
11. (a) A bar of 20mm diameter and 10m long is subjected to an axial pull of 50kN . The extension of the bar is found to be 0.1mm, while decrease in the diameter is found to be 0.15mm. Find the Youngs modulus, Poissons ratio,
(OR)
(b) An aluminium rod of 22 mm diameter passes through a steel tube of 25 mm internal diameter and 3mm thick. The rod and tube are fixed together at the ends at a temperature of 300 C. Find the stresses in the rod and tube when the temperature is raised to 1500 C.
Es = 200KN/mm2 , Eal = 70KN/mm2 αs = 12 × 10−6 /0 C.
