Question 1.
Define the element stiffness matrix in the context of FEM.
Show hintHide hint
Think about how an element responds to loads.
Question 2.
What does a higher stiffness matrix indicate about an element?
Show hintHide hint
Consider the concept 'Stronger means less stretch.'
3Question 3.
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
Show hintHide hint
Think about the role of forces and how they interact with structures.
4Question 4.
True or False: A higher stiffness matrix implies greater deformation under load.
- True
- False
Show hintHide hint
Remember the principle of resistance to deformation.
Question 5.
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.
Show hintHide hint
Recall the key principles of beam bending and how they relate to stiffness.
Question 6.
Given a system of truss elements, calculate the overall stiffness matrix when subjected to a uniform load at different angles.
Show hintHide hint
Consider each element's orientation and how it contributes to the overall system's stiffness.
