2 cards from this section. Quick, good the night before a test.
What is the primary function of the mass matrix in a 2-DOF system?
Think about how mass affects motion.
What command do we use in MATLAB to solve the eigenvalue problem?
This command is short for a mathematical term often used in linear algebra.
What command is used to solve the eigenvalue problem in MATLAB?
Look for the command related to eigenvalues.
True or False: The mass matrix affects how the system responds to external forces.
Think about how mass influences movement.
A structure has a mass matrix of M = [500 0; 0 1500] and a stiffness matrix of K = [20000 -5000; -5000 30000]. Compute the natural frequencies.
Remember to inspect the diagonal of the D matrix.
Consider a 2-DOF system under harmonic excitation. Write a MATLAB script segment to simulate the system response over time for given force inputs.
Utilize the previously defined matrices and modal responses.
