Question $2$: $(30$ marks$)$

a$.$ Draw the primary and redundant structures for the indeterminate structure in fig. $2$ to be used in the flexibility method of analysis. Remove redundant By and Cy to create a cantilever beam for the primary structure. $(10$ marks$)$

b$.$ Write the compatibility equation $($calculate all coefficients needed for the equation$)$ for point $B$ only if point $B$ has an uplift of $0\mathrm{.}02m(0\mathrm{.}02m$ upward movement$)$ if $E=210{10}^{6}K\frac{N}{m^2}$ and $I=5{10}^{-5}{m}^4(20$ marks$)$
