Question 1

What does the stiffness matrix represent in finite element analysis?

  • How much a structure resists forces
  • The total weight of a structure
  • The shape of a structure

💡 Hint: Think about the role of forces and how they interact with structures.

Question 2

True or False: A higher stiffness matrix implies greater deformation under load.

  • True
  • False

💡 Hint: Remember the principle of resistance to deformation.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a simple beam supported at both ends subjected to a central load. Derive the element stiffness matrix for this beam and explain each step in your derivation.

💡 Hint: Recall the key principles of beam bending and how they relate to stiffness.

Question 2

Given a system of truss elements, calculate the overall stiffness matrix when subjected to a uniform load at different angles.

💡 Hint: Consider each element's orientation and how it contributes to the overall system's stiffness.
