Thanks to CuriosityStream for sponsoring this video. Since well before the first Wright brothers flight in 1903, and all the way to the present day, mankind has been fascinated by taking to the skies. Once thought to be impossible, heavier-than-air …

Thanks to Brilliant for sponsoring this video. Beams are used to carry loads in a whole range of different structures, and it’s important for engineers to be able to predict how much a beam will deflect when loads are …

If we apply a load to a beam, it will deform by bending. This generates internal stresses, which can be represented by a shear force acting in the vertical direction, and a bending moment. The shear force is the resultant …

In this video we’re going to take a look at stress transformation and Mohr’s circle. Let’s start by reminding ourselves about the stress element. The stress element is a useful way of describing the stresses acting at a single point …

Analyzing solid mechanics problems in three dimensions can be really hard work, and it can get very complicated very fast. Fortunately in a lot of cases there are some simplifications we can use to reduce a three-dimensional problem to a …

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 …
