Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Analyze a beam with deflection influenced by $q(x) = 10 ext{ln}(x)$; derive the governing equations and apply variation of parameters.

💡 Hint: Break it down step-by-step to isolate $g(x)$ and integrate accordingly.

Challenge 2 Hard

A structural analysis shows a vibration response described by $F(t) = t^3 e^t$. Apply variation of parameters to propose a solution method.

💡 Hint: Focus on solving the ordinary differential equation systematically!
