Problem 5.1

On my honor, I have neither given nor received unauthorized aid in doing this assignment. 

Given[edit | edit source]

Find[edit | edit source]

Solve by hand the gen. eigenvalue problem for the spring-mass-damper system on p.53-13, using the data for the masses in (2) p.53-13b, and the data for the stiffness coefficients in (4) p.53-13b.

Solution[edit | edit source]

First plug given values into the stiffness matrix:

Next plug stiffness matrix in equation below:

Take the determinant:


Using the Quadratic formula to solve:

Final gamma values:

To find the eigenvectors, first we:

To solve, lets set equal to 1:

Multiplying out the matrices, we obtain:

Using the same process we find :

Multiplying out the matrices, we obtain:
