The figure below illustrates a twodegreeof
freedom system. Mass m₁ = 10 kg is located at the
end of a clamped beam with a mass of my = 10 kg,
a Flexural rigidity of EI = 4000 Nm², and a length
of L = 2 m. Mass m₁ is connected to mass
m2 = 20 kg using two springs, k₁ = 1000 N/m
and k2 = 3000 N/m, as shown in the figure.
Determine the second mode shape vector?
