Challenge Problems
Push your limits with advanced challenges
You have a truss structure made of four members connected at node A. If the stiffness of each member is known, derive the global stiffness matrix and examine how applying a force at node B affects the structure.
💡 Hint: Consider the connectivity and contribution of each element to the nodes.
Analyze the impact of not applying appropriate boundary conditions to a cantilever beam under point load. Illustrate the effects on the results interpreted from the stiffness matrix.
💡 Hint: Think about how the beam would physically behave if it was not fixed at one end.
