2. Write down Maxwell’s reciprocal theorem.
3. A fixed beam of span ‘L’ is subjected to UDL throughout w/m. What is end moments and moment at the centre?
4. Draw BMD for a propped cantilever beam span ‘L’ subjected to UDL throughout w/m.
5. Define core of a section and draw the same for a circular section.
6. Write Rankine’s equation for column.
7. Define principal plane and principal stress.
8. State the principal stress theory of failure.
9. What is ‘fatigue strength’ and ‘endurance ratio’ in a fatigue testing of material?
10. Write the Winkler-Bach formula for a curved beam.
