Torsion is the twisting of an object, caused by a moment acting about the object’s longitudinal axis. It is a type of deformation. A moment which tends to cause twisting is called torque. A common example of an object subjected …

Let’s say we have a plank of wood which we would like to use to cross a canal. It has a rectangular cross-section and so we could either use it like we have done here, or we could rotate it …

we’re going to take a closer look at strength, ductility and toughness – three very important material properties. Let’s get started! Strength is a measure of the stress a material can withstand. Two different values are typically used to …

Stress and strain are fundamental concepts that are used to describe how a body responds to external loads. In this video we’ll explore these concepts using the simple example of a loaded bar. Here we have a solid metal …
