Challenge Problems

Push your limits with challenges.

Question 1

Given a state of stress at a point with principal stresses σ₁ = 80 MPa, σ₂ = 30 MPa, and these align with the x and y axes. Illustrate the reduced square representation and label all stress components.

💡 Hint: Ensure proper alignment of all components according to the principal stresses.

Question 2

A beam experiences an axial force resulting in a normal stress of σₓₓ = 50 MPa and σᵧᵧ = 20 MPa with no shear. Write down equations to reduce to the square representation and solve for τ if needed.

💡 Hint: Draw the stress representation accurately and write the stress transformation equations involved.
