Task 4
A support beam is subjected to vibrations along its length, emanating from two machines
situated at opposite ends of the beam. The displacement caused by the vibrations can be
modelled by the following equations,x1 = 3.75 sin ( 100nt +
mm
x2 = 4.42 sin ( 100nt – ),
mm
a. State the amplitude, phase, frequency and periodic time of each of these waves.
b. When both machines are switched on, how many seconds does it take for each machine
to produce its maximum displacement?
c. At what time does each vibration first reach a displacement of -2mm?
d. Use the compound angle formulae to expand x, and x2 into the form A sin 100t ±
B cos 100nt, where A and B are numbers to be found.
e. Using your answers from part d, express ( x1 +x2), ( 2x1 – 4x2), and ( x1 + x2)( 2x1 –
4x2) in a similar forms. Convert this expression into the equivalent forms of
R sin(100tbt +a).
