Topic: Stiffness Matrix Method $($Truss$)$

Question:

Using the stiffness method, determine the horizon$-$

tal and vertical components of displacement of joint $1$ in

Figure P$15\mathrm{.}2.$ Also compute all bar forces. For all bars, $L$

$=20ft,E=30,000$kip$\frac{s}{i}{n}^2,$ and $A=3i{n}^2.$please answer this with drawing the degrees of freedom in figure..

Thank you..
