Do you know a thermoplastic as highly performing as Torlon®? The other name for this strong material is polyamide-imide (PAI). PAI’s excellent chemical and physical properties enable it to perform reliably under harsh conditions at temperatures of up to 260 degrees centigrade. With its outstanding creep and wear resistance, this material finds use in many …

Before diving in to take a deeper look at the different types and units of modulus of elasticity (Young’s Modulus), let’s first take a look at a broad definition of this highly important mechanical property. A basic definition of modulus of elasticity Also known as ‘elastic modulus’, it is a measured value that represents a …

It is very useful for any mechanical engineer to be aware of 4130 steel properties. 4130 steel, otherwise known as Chromoly or chromium molybdenum steel alloy, is made with 0.8 to 1.1% chromium and 0.15 to 0.25% molybdenum as strengthening agents. steel properties make it a versatile metal, especially mechanical properties such as high ductility, …
Polypropylene is widely regarded as one of the most versatile plastics. Just look around and you will surely spot it, albeit in different forms – whether it’s in your kitchen (appliances, cutlery and utensils), around your living room (furniture, carpets, rugs), your kids’ room (toys), your garage (car batteries, packaging material) or even your closet …
ISO 2768 standard is a creation of the International Organization for Standardization (ISO). Like for any other standard of this nature, the technical committee was the team behind this work. Other participants in this process were international organizations, governmental organizations, NGOs and other interested parties. This standard, generally titled “General Tolerances”, consists of two parts: …
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 of the first things any engineer worth their salt needs to master. The main reason steel is so popular is due to the fact it’s relatively light and easy to …
Many of us lucky enough not to live in areas which are frequently susceptible to tornadoes can only look on as we see images on the television. The so-called “Tornado Alley” in the Midwest and to a lesser extent the South-East of the USA are regularly hit by tornadoes which can literally rip properties from …

While biomaterials have made enormous progress in recent times, the concept of biomaterials has been around for centuries. In its most basic form it goes back to the Egyptians who used animal sinew to stitch open wounds on humans. It is the fact that the animal sinew used did not prompt a reaction from the …

Since the days of the caveman we have seen the emergence of simple drainage systems. Used as means to reduce flood dangers or improve irrigation the basic design and structure has remained remarkably constant. We will now take a look at the French drain which has been extremely effective for nearly 200 years. What is …
