Calculate the interpolation functions for the linear $($a$)$ trianqular and

$($b$)$ rectangular linear elements shown.

$($c$)$ The elements shown are subjected to distributed load f$\_($e$)=1.$ Note that f$\_($e$)$ is distributed evenly between grid points. Calculate the elemental stiffness matrix and elemental force vector for the elements.

Please don't use AI$.$ It doesn't solve it correctly. I pay for a human to help me understand how to do things. Do the work yourself, show your work, and make sure it's correct before you submit it$.$ I will thumbs up ONLY if you do this. Thank you
