Simple Truss

Force $P=1,943N$ is applied at a joint $B$ of the above truss.

The members of the bar are cylindrical bars.

Hint: You can use the following incomplete Python code snippet in Colab to solve the problem:

import numpy as $np$

from scipy import linalg

$P=???$ # $($N$)$ #Plug in given value

$D=???$ # $(cm)$ #Plug in given value

$.$ sqrt$(2)/2],[0,1,-$np$.$sqrt$(2)/2],[0,1,0]])$

print$($A$)$

$B=np*array([P,,P])$

$x=$linalg$*solve(A,B)$

print $(x)$

print $($X$[2])$

Stress$=???$ # Fill in this line of code appropriately

print$(\text{'}$Stress$=\text{'},$ np$.$round$($Stress$*1$e$-6,2),$ 'MPa' $)$
