Challenge Problems
Push your limits with challenges.
Question 1
A beam subjected to axial and shear loads has principal stresses of 150 MPa and -50 MPa. Calculate the von Mises stress and determine if the beam would fail if the yield strength is 200 MPa.
💡 Hint: Make sure to use the correct formula and substitute carefully.
Question 2
Design a simple cylindrical hub that must withstand a torsional load of 150 Nm. Given the yield strength of the material is 300 MPa, determine the required diameter if the permissible von Mises stress is not to exceed 200 MPa.
💡 Hint: Apply torsion concepts and keep in mind the safety margins.
