Dynamometer – types, working principle and power measurement basics

A dynamometer is a power measurement instrument used to determination the work being done by a machine over time. Work is the force vector that acts in such a way and direction that it results in the displacement of a mass. So, the action of lifting a bucket of water in a time period of …

Photogrammetry in mechanical engineering

Photogrammetry in mechanical engineering

Photogrammetry in mechanical engineering is becoming more popular, so let’s take a look at the concept and how it’s used. Photogrammetry derives from the Greek words photos, meaning light, gramma, meaning record, and metreo, which means measurement. It’s a process that has been used since the mid 19th century, of taking measurements from photographs. Obviously, the …

What is a Profilometer and why is it used?

A profilometer is a highly specialised meteorological measurement device that is used for the determination of the roughness of a surface. As a measurement instrument, the profilometer is very precise as it is expected to have the capacity to identify and quantify very small-scale surface features. The roughness of a surface is categorised in grades …

Enter the world of Microtomography

What is Microtomography?

Heterogeneous materials are gaining more popularity in use for manufacturing high-tech parts. This means that analyses and certifications need to be conducted and will therefore require a thorough understanding of the behavior and responses of such parts. While many are working on analytical and mathematical models to describe the properties of these materials, there is …
