When the force, P, is removed from a displaced beam, the beam will return to its original shape. However, inertia of the beam will cause the beam to vibrate around that initial location. Assuming the elastic modulus, inertia, and cross sectional area (A) are constant along the beam length, the equation for that vibration is (Volterra, p. 310)

Mar 30, 2016 · Vibration Fixture Basics March 30, 2016. By Randall Cobb, P.E. Inside Sales Manager, NTS Detroit. Vibration testing is a necessary part of many programs, and there are a wide variety of vibration types, but the one thing every test has in common is that the energy must be transmitted into the test sample with some kind of fixturing. Fixturing can be as simple as mounting bolts into a flat ...

Vibrations of Structures/Introduction to vibrations ...

The inertial force occurs because acceleration is present. We know if a body having mass 'm' is moving with an acceleration 'a' then the force acting on it is the inertial force given by : = ∗ The Spring force arises due to the elasticity of the material. It is proportional to the displacement.

A simple example of harmonic motion is a mass connected to a flexible cantilevered beam. External force, either from a one-time impulse or from a periodic force such as vibration, will cause the system to resonate as the spring alternately stores and imparts energy to the moving mass.
