SOLID MECHANICS
Q1.

 Which of the following statements are not correct ?

  1.  Strain energy method can be used to find out the deflection of members only .
  2.  Strain energy method can be used for a section having variable flexural rigidity .
  3. Castigliano's first theorem gives the deflection at a point .
  4.  Moment area method cannot be used for the beams having variable section properties .
: min

Statements- Castigliano's first theorem : the first partial derivative of the total internal energy (strain energy) in a structure with respect to any particular deflection component at a point is equal to the force applied at that point . and in the direction corresponding to that deflection component .
