Challenge Problems
Push your limits with advanced challenges
A beam has a triangular loading on its length. Calculate the maximum bending stress if the beam supports a maximum bending moment of 1500 in-lb.
💡 Hint: Remember you may need to calculate the moment of inertia first depending on the shape.
Two beams with different moments of inertia are subjected to the same bending moment. Discuss how the bending stress varies between them.
💡 Hint: Use the bending stress equation and compare the values.
