First law and its applications

Elasticity Elasticity is defined as the property of an object under which it resists any kind of change in its dimensions such as size and shape when any deforming force is exerted on it and regains its shape and size after the removal of the applied deforming force. Stress  When the deforming force is applied […]

The eruption of lava from a volcano occurs when hot materials from the Earth’s interior are ejected from the volcano’s vent. Volcanic eruptions can occur from either the side branches or the summit of the volcano. Some eruptions are violent explosions that eject massive amounts of rock and volcanic ash into the atmosphere, causing widespread

The concept of Variations of the Equation sets a relationship between two variables in such a way that one variable is equal to constant multiplied by the other variable. Thus, the concept tries to create a dependency between two variables. The field of physics uses this concept very frequently.  For instance, we have the formula

In material science and engineering, we always try to know more about the behaviour of a rigid body when it goes through stretching, twisting and squeezing. We make our effort to understand the behaviour of rigid bodies by establishing a relation between applied force and deformation. So to understand the mechanical properties of a substance,

The perpendicular force per unit area, or the tension at a point within a confined fluid, is known as pressure in the physical sciences. The force exerted on a floor by a 42-pound box with an area of 84 square inches at the bottom is equal to the force divided by the area over which

A matrix is a specific collection of elements organised in rows and columns. A matrix’s order is the number of rows x the number of columns. For instance, a 2*2 matrix means it contains two rows and two columns. We can only discover the matrix inverse for square matrices with equal numbers of rows and

THE FIRST LAW OF THERMODYNAMICS The first law of thermodynamics was drawn from the law of conservation of energy and the thermodynamics process. It also differentiates the two kinds of transfer of energy: Heat Thermodynamics work One needs to understand heat, mass, and internal energy before stating the first law of thermodynamics The energy associated

Surface tension is the property of liquid by virtue of which the free surface of liquid tends to shrink into the minimum surface area possible.  It is denoted by S. Surface tension is only concerned with liquids not gases as gases do not have free surface. Examples of surface tension are:  oil and water do

Introduction Surface Tension Surface tension is the energy or work required to raise the surface area of a liquid due to intermolecular forces. Because the composition of the liquid (e.g., water vs gasoline) and the solutes in the liquid (e.g., surfactants like detergent) influence these intermolecular pressures, each solution has different surface tension features. Surface

The geometrical description of the part of the space filled by an object, as specified by its external limits, is called its shape. Deformation is defined as a change in shape caused by the application of force. Deformation is known to occur even when minimal forces are applied. Deformation Process Deformation is the change of
