Terminal Velocity

Terminal velocity is the most velocity attainable by an object because it falls through a fluid (air is the commonest example). This usually happens or occurs when the total of the sum of the drag force (Fd) and also the buoyancy is equal or the same with the downward force of gravity (FG) acting on … Read more

Stress-Strain Relationship

The relationship between the strain and stress that is displayed by the particular material is known as the stress-strain relationship of that material. For each material, this relationship is unique and is determined by recording the amount of strain or deformation at distinct intervals of the multiple kinds of loadings or stress. Uses of Stress-Strain … Read more

Streamline and Turbulent flow

Streamline the flow of a liquid is that flow during which every component of the liquid passing through a point travels on a similar path and with the same speed because the preceding component passes through that point. A streamline is also defined as the path, straight or curving, the tangent to which at any … Read more

Stoke’s Law

Stoke’s law is the basis of the falling-sphere measuring instrument, in which the fluid is stationary in a very vertical glass tube. A sphere of well-known size and density is allowed to go up through the liquid. If properly selected, it reaches velocity, which may be measured by the time it takes to pass two … Read more

Pascal’s law

Pascal’s law and its applications (hydraulic lift and hydraulic brakes) Pascal’s Law states that the pressure applied to a fluid in a much-closed container is transmitted equally to all or any points within the fluid and act in all directions of the container. Pascal’s Law is applicable to both solids and liquids. The law was … Read more

Hooke’s Law

Hooke’s law is the law of elasticity which was discovered in 1660 by the English scientist, Robert Hook. This law is compatible with Newton’s law of the static equilibrium. This law states that for the relatively small deformations of the objects, the size of deformation or displacement is directly proportional to the force or load, … Read more

Kepler’s law of planetary motion

Johannes Kepler was the German astronomer who observed the first two laws of planetary motion. These laws state that all planets move about the sun in elliptical orbits and having the sun as the foci. Secondly, it states that a radius vector joining the sun sweeps out equal areas in equal lengths of time. And … Read more

Gravitational potential energy and gravitational potential

Gravitational potential energy is the energy of an object possesses because of its position in a gravitational field as it represents the potential of an object which has to do some work as a result of being located at a particular position in a gravitational field. Gravitational field intensity is zero at infinity and it … Read more

Elastic Behavior

The elasticity of the materials is the specific property which helps to resists the permanent change when any sort of stress is applied to this body. When the stress application is stopped the body can regain the original size and shape. The elastic behavior is different for different materials. The study of the properties that … Read more

Critical Velocity

Critical velocity is defined as the speed at which a falling object reaches when both gravity and air resistance are equalized on the object. The other method of Elaborating critical velocity is that the speed and direction at which the fluid will flow through a passage without turning into turbulent. Turbulent flow is outlined as … Read more
