A tensile load (P) acts on an axial member of length (l) and cross-sectional area (A). If (E) is the elastic modulus, the axial stiffness of the member is:

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?
