A simply supported beam of span 6 m carries a point load at the center such that the maximum bending moment under the load is 12 kN-m. If EI is the flexural rigidity of the beam, the deflection at the center 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?
