Webpoint. The stress transformation relation for any other orientation (e.g., x', y') is found by applying equilibrium equations (∑ F=0 and ∑ M = 0 ) keeping in mind that F n = σ A and F t = τA . The rotated axes and functions for incremental area are shown in Fig. 2.3. The forces in the x and y directions due to F n = σ A and F t = τA and ... WebThe rotated normal stresses are equal when the shear stress is a maximum, giving . σ x′ = σ y′ = (σ x + σ y)/2 = 37.95/2 = 18.98 MPa . All rotated stresses are labeled on the stress element at the left. Notice, the shear stress is actually negative when the shear stress rotation equation is used.
