A Wheatstone bridge is a special type of electrical circuit that is used to accurately measure the unknown resistance of a component. It was also

Laminar flow is a phenomenon observed in flowing fluids that manifests during the study of fluid dynamics. In general, fluid flow can be described in

In simplest terms, the viscosity of a fluid is the measurement of its resistance to deformation at a specified rate. For liquids, viscosity directly corresponds

Constant force springs differ from traditional helically-wound springs. They are made from pre-tensioned, high yield strips of metal (often stainless steel) as opposed to wire.

Poisson’s ratio is a value that defines the amount of contraction that occurs when something is stretched, or the amount of expansion when an object

Most engineering installations and equipment are subjected to (and designed to withstand) a variety of atmospheric conditions and over a wide range of temperature, pressure,

The act of measuring has become an important part of our everyday lives. The need to measure and standardise has developed into the science of

In the study of electronics, many laws and theories exist. These laws enable us to understand the workings of electric circuits and components. One such

Taps are cutting tools used by machinists to cut or form screw threads. The first recorded use of taps in metalworking is placed sometime in

The Taylor Functions are series of sum terms that concern the values of the derivatives of a given function at a given point, so they

Did you realise that when you rub your hands together while washing, you are causing shear stress on the surface of your hands? Or that

Defining and understanding the basic structural concepts of engineering and how they are expressed in physics and mathematics is a key aspect for students. This

Have you come across Pascals as a unit of pressure and not quite sure what it is? Pressure can be a bit confusing. There are

Before defining the volumetric flow rate equation and how to apply it, let’s explore the concept of volumetric flow and how the principle is used

Resonant frequency can apply to many areas of the physical sciences or engineering. Thus, there is more than one resonant frequency equation, depending on the

Steel columns and beams are the building blocks of most major commercial construction these days. Therefore, knowing how to design a steel column is one

Are you looking to convert millimeters to inches? Look no further, with our instant mm to inches calculator, you can do it in a second.

Compression springs are mechanical devices that are specifically designed to be induced to axial compression loads. They can usually also be extended as well as

I don’t think there is a mechanical engineer out there who doesn’t have a soft spot for gears. There’s just something about spinning bits of

Viscosity refers to the amount that a fluid (gas or liquid) resists changing shape. In other words, how much a fluid opposes flow. Therefore, the

Have you ever wondered why gauge symmetry is synonymous with electromagnetism equations? Anytime the topic comes up, it reminds us of Maxwell’s electrodynamics. Gauge field

As engineers, we have all used thread sealing tapes at some point to fix leaks. But how do we fix leaks in applications that involve

Thermal engineering is one of the most fundamental areas of mechanical and chemical engineering, with the study of heat transfer being one of the most

Below is a handy Reynolds Number Calculator. The Reynolds number (Re) is a dimensionless quantity that is used to determine what type of fluid flow to

Mechanical engineers need to be able to calculate things! One of the most important things a mechanical engineer must know are basic stress analysis calculations.

In this article, we will explore an interesting engineering concept and learn about the calculations which explain its effects. We will study is the ‘Venturi

The difference between school and “real life” problem solving When we pass from high school to university we bring with us the idea that answers

Engineers are supposed to do calculations. That’s what we do. We calculate everything from strength and mass flow, temperature rise and heat transfer, fuel consumption and

As a general rule, a mechanical measure cannot be written without a precision. When a study does not contain an error range estimation or analysis,

We’ve previously spoken about the concepts of accuracy and precision and how they play a key role in determining the error range in mechanical engineering

We deal with numbers in every aspect of life. In mechanics, understanding the more obscure concepts and definitions can be critical to our designs. Most

This article is a basic look at thermal materials that are available today, and general design considerations for thermal design. This article covers thermal conductivity,

This article helps mechanical engineers understand the selection of ball bearings depending upon the application and load conditions. Primarily the article helps you calculate the

Natural convection has been used to cool electronics for ages. It is a simple and reliable method. The big drawback, of coarse, is that the

Here’s a useful guide to calculating the area of basic shapes. Rectangle Area = w × h w = width h = height Triangle Area

Here’s is a great piece of freeware. It’s simply called “convert” by Josh Madison. It’s an amazingly useful program – something that every mechanical engineer

Brakes are machine elements that absorb kinetic or potential energy in the processes of slowing down or stopping a moving part. The absorbed energy is
