Hi! Is anyone experienced With T&D calculations using above mentioned model: ?
I have a trouble to understand what exactly F1 is and how to calculate it. I know it is an axial force, so it is drag? And once you calculate drag for one element, you use it as F1 to calculate drag in 2ns element...
Right, I see now. I want to calculate displacement in pipe using dynamic eq. [M]{U''}+[C]{U'}+[K]{U}={F}, where U is displacement, and U' and U'' are its derivateves. M, C, K are matrices of mass, damping and stiffness. Matrices are defined, and some of the expressions contain Ixy and Iz (area...
OK, thank you! I understand that it is a confusing question, let's say z in the vertical axis. I wanted to see your opinions on this one, as I didn't see the difference between body's moment of inertia in different axes...
Hi, I've been always using eq. I=Pi*(D^4-d^4)/64 to find moment of inertia of a pipe. Recently I've seen that moment can be in different directions, and then it is expressed differently. So what is the difference between Ixy and Iz?
