यदि किसी पदार्थ का प्रत्यास्थता मापांक (modulus of elasticity) E, उसके दृढ़ता मापांक (modulus of rigidity) G का दोगुना है, तो उसका आयतन प्रत्यास्थता मापांक (bulk modulus) K क्या होगा?

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?
