The differential equation for small-amplitude vibrations y(x,t) of a simple beam is
given by
ππππ ππ 2ππ
πππ‘π‘ 2 + πΈπΈπΈπΈ ππ 4ππ
ππππ4 = 0
where Ο = beam material density, A = cross-sectional area, I = area moment of inertia, E =
Youngβs modulus. Use only the quantities Ο, E, and A to non-dimensionalize y, x, and t, and
rewrite the differential equation in dimensionless form. Do any parameters remain? Could they
be removed by further manipulation of the variables
