9. Mistakes (or) Gauss Errors:

Depends upon the observer, a mistake cannot be corrected unless the observer get training. The mistakes are errors that arise from inattention, inexperience, carelessness and poor judgement of confusion in the mind of observer.

10. Conditioned Quantity:

CE6402 IMPORTANT QUESTIONS STRENGTH OF MATERIALS

CE6402 IMPORTANT QUESTIONS STRENGTH OF MATERIALS REGULATION 2013 ANNA UNIVERSITY

Sample for Ce6402 important questions:

1. Define: Strain Energy

When an elastic body is under the action of external forces the body deforms and work is done by these forces. If a strained, perfectly elastic body is allowed to recover slowly to its unstrained state. It is capable of giving back all the work done by these external forces. This work done in straining such a body may be regarded as energy stored in a body and is called strain energy or
resilience.

2. Define: Proof Resilience.
The maximum energy stored in the body within the elastic limit is called Proof Resilience.

3. Write the Castigliano‟s first theorem.

In any beam or truss subjected to any load system, the deflection at any point is given by the partial differential coefficient of the total strain energy stored with respect to force acting at a point.

4. What are uses of Castigliano‟s first theorem?

  • To determine the deflection of complicated structure.
  • To determine the deflection of curved beams, springs.

5. Compare the unit load method and Castigliano‟s first theorem

In the unit load method, one has to analyze the frame twice to find the load and
deflection. While in the latter method, only one analysis is needed.

6. Define : Modulus of resilience.

The proof resilience of a body per unit volume. (ie) The maximum energy stored in the body within the elastic limit per unit volume.

7. Define : Trussed Beam.

A beam strengthened by providing ties and struts is known as Trussed Beams.
