### Wheatstone Bridge

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

### Kinematic Viscosity

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 spring: properties and design equations

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 for Boneheads, plus FAQ

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

### Mollier Diagram – A Basic Guide

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,

### Metrology – a mechanical engineer’s guide

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

### What is Watt’s law?

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

### Taylor Functions – explanation and software tools

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

### Shear Stress Equations with Explanation

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

### Structural Concepts – Static and dynamic load basics

### Pascals explained: A simplified guide for boneheads

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

### Volumetric Flow Rate Equation

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 Equation: mechanical, electrical and acoustic

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

### How to Design a Steel Column

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

### Lift Equation – fully explained and simplified for beginners

It has been observed that most aircraft accidents occur during the take-off or landing phase of the flight. Lift is a major part of takeoff.

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.

### Planetary Gears – a masterclass for mechanical engineers

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 of Water – the Ultimate Guide

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

### Gauge Symmetry for Boneheads – a brief explanation of the fundamentals.

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
