For the two shown in figure k & m are equal in followings:
K = 100 k/in, m= 1000 lb/g for student last names (A-K), K = 200 k/in, m= 2500 lb/g
for students last names (L-S),(K = 250 k/in, m= 2750 lb/g for students last name (T-Z).
Solve only one of the following requirements based on your last name:
Verify the modes are orthogonal (for
student last names A-K)
m
Normalize the first mode.
(for students last names L-S)
Using Electro with 2% damping,
determine Sa & Sd only for the first
