Longitudinal and Transverse Vibrations: Introduction
Introduction:           When elastic bodies such as a spring, a beam and a shaft are displaced from the equilibrium position by the application of external forces, and then released, they execute a   vibratory motion . This is due to the reason that, when a...

Terms Used in Vibratory Motion
          The following terms are commonly used in connection with the vibratory motions: 1. Period of vibration or time period: It is the time interval after which the motion is repeated itself. The period of vibration is usually expressed in seconds. 2. C...

Types of Vibratory Motion
The following types of vibratory motion are important from the subject point of view: 1. Free or Natural vibrations: When no external force acts on the body, after giving it an initial displacement, then the body is said to be under Free or Natural vibratio...

Types of Free Vibrations
          The following three types of free vibrations are important from the subject point of view: 1. Longitudinal vibrations, 2. Transverse vibrations, and 3. Torsional vibrations.           Consider a weightless constraint (spring or shaft) whose one en...

Natural Frequency of Free Longitudinal Vibrations
          The natural frequency of the free longitudinal vibrations may be determined by the following three methods: 1. Equilibrium Method:           Consider a constraint (i.e spring) of negligable mass in an unstained position, as shown in Fig (a).,     ...
