State second law of Thermodynamics
On the basis of the experimental results of the Carnot’s engine scientists described how the heat is transferred from one system to the other. They…
What is Forced Oscillations
When a vibrating body is maintained in the state of vibration by a periodic force of frequency (n) other than its natural frequency of the…
Types of Oscillations
Oscillation is defined as the process of repeating variations of any quantity or measure about its equilibrium value in time. The most common examples for…
Laws of Pendulum
From the expression for the time period of oscillations of a pendulum the following laws are enunciated: (i) The law of length: The period of…
Oscillations of Simple Pendulum
A simple pendulum consists of the massless and inelastic thread whose one end is fixed to a rigid support and a small bob of mass…
Oscillation of Liquid Column in a U – tube
Consider a non-viscous liquid column of length/of uniform cross-sectional area A (Figure). Initially, the level of liquid in the limbs is the same. If the…
Explain When two Springs are Connected in Parallel
When two Springs are Connected in Parallel: Two springs of spring factors k1 and k2 are suspended from a rigid support as shown in Figure.…
Horizontal Oscillations of Spring
Consider a mass (m) attached to an end of a spiral spring (which obeys Hooke’s law) whose other end is fixed to a support as…
Dynamics of Harmonic Oscillations
The harmonic oscillations of a physical system results from two basic properties namely elasticity and inertia. Let consider a body displaced from a mean position.…
