# Example 22.2
m0 = 10 kg
k = 1.5 N m / rad
io = (1/12) * m0 * ((0.2 m)^2 + (0.3 m)^2)
tau = 2 * pi() * sqrt(io / k)

# Example 22.3
omn2 = 20 rad^2 /s^2
om = sqrt(omn2)
tau = 2 * pi() / om

# Example 22.4
om2 = 368 rad^2 / s^2
tau = 2 * pi() / sqrt(om2)

# Example 22.7
MKS(mm)
del0 = 10 mm
om0 = 8 rad/s
k = 800 N/m
m0 = 20 kg
omn = sqrt(4 * k / m0)
ymax = del0 / (1 - (om0 / omn)^2)

# Example 22.8
MKS(N)
m0 = 30 kg
k = 200 N/m
mr = 4 kg
r = 60 mm
om = 10 rad/s
damp = 0.15
f = mr * r * om^2
omn = sqrt(4 * k / m0)
y = om / omn
cprime = (f / (4 * k)) / sqrt((1 - y^2)^2 + 4 * damp^2 * y^2)
