Challenge Problems
Push your limits with challenges.
Question 1
A structural engineer assesses a beam under load experiencing three principal stresses: λ1 = 100 MPa, λ2 = 50 MPa, and λ3 = 20 MPa. Calculate the maximum shear stress and identify the stress states represented.
💡 Hint: What is the typical formula for shear stress in relation to principal stresses?
Question 2
Describe how the Mohr's stress plane would appear if λ2 approached λ3, and what implications this has for the material's behavior.
💡 Hint: Think about scenarios where stresses become similar and visualize the Mohr's circle dimensions.
