Principal plane is a plane on which shear stress is zero.

The normal stress acting normal to the principal plane is called the principal stress.

On the planes, other than principal planes, the normal stress is accompanied by the tangential stresses.

Two principal planes carrying the maximum and minimum direct stresses are always collinear.

equal both in magnitude and sign

equal in magnitude but opposite in sign

unequal in magnitude but of same sign

equal in magnitude, and the direction may be same or opposite

τ₁ - τ₃ and τ₂ = τ₄

τ₁₌ τ₄ and τ₂ = τ₃

τ₁ = 2τ₄ and τ₂ = 2 τ₃

τ₁ = τ₂ = τ₃ = τ₄

the normal stress is maximum or minimum and the shear stress is zero

the tensile and compressive stresses are zero

the tensile stress is zero and the shear stress is maximum

no stress acts
