=5) Compute reactions.=

- 2 methods:

5.1) use element FD relationships.

$$ \ k^{(e)}*d^{(e)} = f^{(e)}, e = 1, 2 $$

 Elem 1 (e=1): 

$$ \ k^{(e)}*d^{(e)} = f^{(e)} $$

k is know d is know f is unknown

$$d^{(1)} = \begin{Bmatrix} 0 \\ 0 \\ 4.352 \\ 6.1271 \end{Bmatrix}$$

 Elem 2 (e=2): 

$$ \ k^{(e)}*d^{(e)} = f^{(e)} $$

k is know d is know f is unknown

$$d^{(1)} = \begin{Bmatrix} 4.352 \\ 6.1271 \\ 0 \\ 0 \end{Bmatrix}$$
