Structural analysis Definition and 56 Threads

The two steel channels shown are arranged to form a compound section in which Ixx=Iyy. Determine the value of the dimension 's' that will satisfy this condition. We have been working on radius of gyration, section modulus, second moment of area, the parallel axis theorem, polar second...

Homework Statement http://antishift.org/image.php?id=16122&size=medium Homework Equations Static Equilibrium equations: since most of the supports are rollers, only y-forces are considered as well as moment equations. I'm pretty sure E and F are hinges so there are no moments around E and F.The...

An extremely useful set of lecture notes for anyone who wants to investigate statics of indeterminate structures (i.e. the force and displacement methods). Influence lines are included too. http://www.ecf.utoronto.ca/apsc/courses/civ214/Lecture%20notes.html"

I'm afraid I have another problem to be solved I don't quiet understand, thanks to my poor english and some information missing in the course notes. ---- You are writing a 2-dimensional finite element programming code to be used in the structural analysis of a material with a newly...

This is a HW question, and I posted it in the HW section, but no one there seems interested. Perhaps somewhere here would be willing to lend a hand? See the problem in the attachment. I basically don't know if I am on the right track. I started with part a) by trying to find the force...
