## 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
