Problem $2(35$ points$)$

We are given the statically indeterminate structure shown in Fig. $2$a$.$ We are also given a potentially helpful solution, shown in Fig. $2b.$ We know that $EI={10}^6$kip$*f{t}^2$ for member $AB,EI=8*{10}^5$kip$*f{t}^2$ for member $BC.$ Finally, we are given $a_T=\frac{{10}^{-5}}{}F$ and the sectional depth $h=1ft$ for both members.

The axial contribution to deformations can be neglected

Calculate the support reactions for the structure.

Problem $3(20$ points$)$

We are given the structure shown in Figure $3,$ subjected to vertical $($gravity$)$ and horizontal $($lateral$)$ loads.

Find the approximate support reactions at point $A,$ due to combined $($simultaneous$)$ action of horizontal and vertical loads.
