For a given mechanical system shown in the diagram, it is necessary to determine the natural frequency of vibration.
A mechanical system in an equilibrium position can freely oscillate around the horizontal axis z passing through a fixed point O. The system consists of thin homogeneous rods 1 and 2 or a homogeneous plate 3, rigidly fastened to each other, as well as a point load 4. Mass of one meter of length rods 1 and 2 is 25 kg, the mass of plate 3 per square meter of area is 50 kg, and the mass of point load 4 is 20 kg. The stiffness coefficient of the elastic elements is c = 10 kN/m. The dimensions of the system parts are indicated in meters.
To determine the natural frequency of vibration of a given mechanical system, it is necessary to use the formula:
f = (1/2π) * √(k/m)
where k is the stiffness coefficient, m is the mass of the system.
Applying this formula, we get:
Thus, the natural frequency of vibration of a given mechanical system depends on its configuration and can be determined by the formula.
