Challenge Problems
Push your limits with advanced challenges
Consider a steel beam subjected to a load that induces torsion. Calculate the shear stress and angle of twist at different points along the beam, providing both mathematical derivations and a diagram to illustrate your findings.
💡 Hint: Use the formula τ = T*r/J, where τ is shear stress, T is torque, r is the distance from the center, and J is the polar moment of inertia.
Design a simple structure incorporating a beam subjected to known torsional loads, ensuring to analyze and modify the design for both Saint-Venant's and warping torsion effects.
💡 Hint: Think about how to support the beam and what materials will prevent failure.
