Homework 7 Solution
Consider the 2DOF viscously damped system given in the figure. There is a forcing on m1 as
F1 (t) = 10 sin(t) N where = 32 rad/s.
m1=m2 = 5 kg, k1 = 5000 N/m, k2 = 10000 N/m, k3 = 4000 N/m,

1) Using the International Standard Atmosferic Model or the US Model we can
assume the following:
T0 = 390 R
p0 = 1, 047 psi
a0 = 968 ft/s
its worth mentioning that we can have the same values by using the empirical
