Challenge Problems
Push your limits with advanced challenges
A material has σ_xx = 100 MPa, σ_yy = 50 MPa, and a shear stress of τ = 30 MPa. Construct Mohr's Circle and identify the principal stresses.
💡 Hint: Use the formulas for plotting and radius determination.
Using Mohr’s Circle, determine the shear stress τ for an angle of α = 45° when σ_xx = 70 MPa and σ_yy = 30 MPa.
💡 Hint: Remember to convert the angle to radians if needed for calculations.
