Q. 1 (a)
Define degree of static indeterminacy and degree of kinematic L 2
indeterminacy of a structure. Write and explain equation of the degree of
static indeterminacy of beam.
Analyse the beam as shown in figure 1 using Castigliano’s theorem and L 4
hence find vertical deflection and slope at the free end.

Analyse the rigid jointed frame as shown in the figure 2 using Virtual L 4
Work method and hence find the slope and vertical deflection at the free
end.
