16.
When a body is subjected to bi-axial stress i.e. direct stresses (σx) and (σy) in two mutually perpendicular planes accompanied by a simple shear stress (τxy), then minimum normal stress is
17.
The direct stress, across a principal plane, is known as principal stress.
18.
On one side of a neutral axis of a beam, there is a tensile stress and on the other side of the beam there is a compressive stress.
19.
When a body is subjected to a direct tensile stress (σ), the maximum normal stress is equal to the direct tensile stress.
20.
According to Euler's column theory, the crippling load for a column length (l) hinged at both ends, is
