Find the distance of the shear center from the web center for a thin-walled channel section with dimensions: height h = 250 mm, flange width b = 130 mm, and uniform thickness t = 3 mm.

Mohr's circle reduces to a point when an element is subjected to:

A steel column pinned at both ends has an Euler buckling load of 250 kN. If the column is restrained against lateral movement at its mid-height, its new buckling load will be:

What is the angle between the principal strain axis and the maximum shear strain axis in 2D strain analysis?
