Question

When a member is subjected to axial tensile load, the greatest normal stress is equal to
​

Answer 1

We know that shear stress on an oblique plane at an angle θ to the cross-section of a body which is subjected to a direct tensile stress σ is equal to 2σsin2θ. Thus maximum value of this occurs at θ=45o which is 2σ
