Shear stress is zero at principal plane
Proof of the statement "Shear stress is zero at principal plane." At principal plane shear stress is zero. There is maximum direct or normal stress but no shear stress at principal plane. … [Read more...] about Shear stress is zero at principal plane
Derivation of the angle at which shear stress is maximum
Derivation of the angle at which shear stress is maximum: Shear stress is maximum at 45 degree from the principal plane. Below is the derivation of the angle at which shear stress is maximum. … [Read more...] about Derivation of the angle at which shear stress is maximum

Derivation of maximum normal stress at principal plane
Derivation of maximum normal stress at principal plane To find the maximum value of normal stress at some angle, we have to differentiate the normal stress transformation equation, (which we derived in the previous article) with respect to dθ. Principal Plane : It is the plane at which normal stress attains the maximum value. Below is the derivation of maximum normal stress … [Read more...] about Derivation of maximum normal stress at principal plane
