SECTION-B
2. Explain the terms : gradually applied load, suddenly applied load and load applied with an
impact load.
3. What do you understand by ?Theories of failure?? Name the important theories of failure.
4. What do you mean by ?Lames equation?? How you will drive theses equation?
5. Find an expression for bending stresses produced in a curved bar which is subjected to
bending moment.
6. A wooden beam 100 mm wide and 150 mm deep is simply supported over a span of 4
meters. If shear stress at a section of a beam is 4500 N, find the shear stress at a distance of
25 mm above the NA.
SECTION-C
7. Derive an expression for the stress induced in a body due to suddenly applied load and
hence find the value of extension produced in a body.
8. Differentiate between thick and thin cylinders. Find an expression for the radial pressure
and hoop stress at any point in case of thick cylinder.
9. Find an expression for the circumferential stress and radial stress developed in rotating
solid disc.
