Challenge Problems
Push your limits with challenges.
Question 1
A beam with a hole is subjected to bending forces. Calculate the SCF if the nominal stress is 50 MPa and the maximum stress at the hole is 100 MPa.
💡 Hint: Use the SCF formula.
Question 2
Design a spring that will endure cyclic loads below its endurance limit. Given a yield strength of 200 MPa, suggest an endurance limit of 80 MPa. Justify your reasoning.
💡 Hint: Consider loading limits when designing for fatigue.
