यदि किसी अतिसूक्ष्म अवयव पर σv = 20 kN/m2 (संपीडन) और σh = 40 kN/m2 (संपीडन) है, तो क्षैतिज समतल से 45° पर झुके समतल पर कार्य करने वाला सामान्य प्रतिबल (normal stress) 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?
