The laboratory contains a single-degree-of-freedom
spring-mass apparatus with variable magnetic damping for
experimentation on mass free damped vibrations, forced damped
vibrations, forced transmissibility, base excitation and vibrations
due to rotating unbalance. It is also equipped with vibration
measuring instruments of moderate complexity for the dynamic testing
of structures. These include accelerometers, amplifiers, exciters,
signal generators, data-acquisition system and x-y
plotters.

General Format for Lab Reports
-
TITLE PAGE (l):
Report title, course, your name, date lab performed, date lab due, date report submitted.• OBJECTIVE OF THE
EXPERIMENT (1)Statement of
objective or purpose of the experiment/lab.
-
THEORY/EQUATIONS USED (3):
List the equations
used for your lab calculations
(if
any).
-
SAMPLE
CALCULATIONS/DATA GENERATED (5):
A sample of the calculations you performed to get your
results.
-
PROGRAM
LISTING (5):
A listing of your MATLAB program (if any).
Please remember,
it's what you put in your report that counts and not how much
you
put in it. Some of these labs require you to turn in MATLAB plots, do not turn
in all that
you have printed out, but only what has been asked for. If you
are not sure about what you
need to turn in, please ask the engineer. Once again,
remember that most of the points that you
get for a lab come
from your answers to the questions in the lab handout.
Points may be taken off for
grammar/spelling and sloppy presentation. The reports
should be typewritten. PCs are available in the computer lab for word
processing. All students should know how to operate the equipment in the
lab and take part in the execution of the
lab. It will be reflected in your grades. Question/s about
the labs will be asked on exams. Not specifics, but concepts, methods
and techniques.
