i really appreciate the methodology and your approach. Simple and Precise and easy to follow. nevertheless the last equation used to determine U2 and V2 (ie 28(-0.48u2 -0.36V2), should have been 28(-0.48u2 + 0.36V2) instead. thank you.

If the two rods were of different length, then how would the values outside the matrices be combined in the K = K1 +K2 equation? i.e if one did not have a value of 28x10^3 edit: nvm I figured it out. Thanks for making this tutorial, would be super lost without it :)

Y'all, could anyone remind me why we cross out the first, second, fifth, and sixth rows at 24:08? I understand that the columns are crossed out because we're distributing the fixed displacements but I may have missed why the rows are crossed out. My guess is that we're sort of ignoring the forces at Nodes 1 and 3, and can then assume that they equal 0, thus allowing us to cross out the corresponding rows, but I may be wrong Great video nonetheless. Appreciate it

[@niranjansharma7040]

Those rows and columns represent the node 1 and 3 (Fixed nodes). Since the displacement at fixed node is zero, those rows and columns are crossed out. Thank you

[@davidio1946]

I have one question Mahesh. After finding the boundary conditions how come you did not find the inverse of the matrix?

[@vipinchandra8955]

Inverse is not required we have to find displacement which we can find by solving equations..

Theta for element 2 is 143.13 degrees with respect to x right? so it must be "cos(theta)=-0.8 and sin(theta)=0.6"
