Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

A light balloon that has a volume 2.50 m³ filled with a helium (pne =
0.179 kg/m*) is tied to a light string of length L = 5.50 m. The string is tied to the
ground, forming an "inverted" simple pendulum, as in Figure 2a. If the balloon is
displaced slightly from the equilibrium position, as in Figure 2b (Pair = 1.29 kg/m³).
Determine
a) the spring constant, k,
(Hint : Use an analogy with the mass hanging at the end of a spring. Solve for the
value of k assuming that the restoring force acting on the system takes the same
form as Hooke's law),
b) the time period of its simple harmonic motion
c) the frequency of the simple harmonic motion.
