Homework 3
1.
Problem 3.1 in the textbook.
Note that the “natural frequency” ω
n
is
without
springs k
1
and k
2
and the “resonance frequency” ω
r
is
with
k
1
and
k
2
, which are just added to the system for testing.
Use FBDs to analyze
the system in both configurations to get EOMs and natural/resonance
frequencies.
2.
Problem 3.4 in the textbook.
The EOM for this problem, without the
pressure excitation, is derived in Example 2.2 using energy
considerations.
Derive an EOM that takes p(t) into account by considering
the forces that act on the fluid in the direction of the axis of the tube.
This is the end of the preview.
