Sample CE8395 Question Bank Strength of Materials for Mechanical Engineers:

PART-A (2 Marks)

1. A cylindrical pipe of diameter 1.5 m and thickness 1.5 cm is subjected to an internal fluid pressure of 1.2 N/mm2. Determine the longitudinal stress developed in the pipe.

2. Find the thickness of the pipe due to an internal pressure of 10 N/mm2 if the permissible stress is 120 N/mm2. The diameter of pipe is 750 mm. CE8395 Question Bank Strength of Materials for Mechanical Engineers

3. The principal stress at a point are 100 N/mm2 (tensile) and 50 N/mm2 (compressive) respectively. Calculate the maximum shear stress at this point.

4. A spherical shell of 1 m diameter is subjected to an internal pressure 0.5N/mm2. Find the thickness if the thickness of the shell, if the allowable stress in the material of the shell is 75 N/mm2.

5. Normal stresses s x and s y and shear stress t act at a point. Find the principal stresses and the principal planes. CE8395 Question Bank Strength of Materials for Mechanical Engineers

13. What are the formula for finding circumferential stress and longitudinal stress?

14. What are maximum shear stresses at any point in a cylinder

PART –B ( 16 MARKS) CE8395 Question Bank Strength of Materials for Mechanical Engineers

1.A thin cylinder 1.5 m internal diameter and 5 m long is subjected to an internal pressure of 2 N/mm2. If the maximum stress is limited to 160 N/mm2, find the thickness of the cylinder. E = 200 kN/mm2 and Poisson’s ratio = 0.3. Also find the changes in diameter, length and volume of the cylinder.
