Challenge Problems
Push your limits with advanced challenges
Consider a circular membrane fixed at the edges. Describe how you would apply boundary and initial conditions to model the vibrations under a sudden force applied at the center.
💡 Hint: Start with defining u(r,0)=f(r) for the shape after the force.
Imagine a rectangular membrane with varying tension along different edges. How might you adjust the boundary conditions while still keeping the essence of fixed edges?
💡 Hint: Explore conditions where tension can influence displacement at edges while still maintaining overall fixed conditions.
