Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a two-degree-of-freedom system with known mass and stiffness values. Calculate the natural frequencies and mode shapes using matrix methods. Provide step-by-step reasoning.

💡 Hint: Use the determinant to simplify your calculations.

Challenge 2 Hard

Consider a scenario where the mass distribution changes significantly in a structure. Analyze how this may influence the structure's dynamic response and determine what steps could be taken to mitigate adverse effects.

💡 Hint: Think about how the ground vibrations might interact with the building's new dynamics.
