Question 1
Given a stress state with σ_x = 100 MPa, σ_y = 50 MPa, and τ_xy = 25 MPa, calculate the principal stresses using Mohr's Circle and determine the associated shear stresses on the principal planes.
💡 Hint: Remember to find the center using the average of σ_x and σ_y.
Question 2
Explain why shear stress can appear negative when analyzed between two opposing planes in Mohr’s Circle, and provide a mathematical example.
💡 Hint: Think about sign changes and their impact during stress state transitions.
