How can we measure the friction and wear of wires in sliding contacts?

WHY

In everyday life we come across and use applications were wires are operated in sliding contacts. Some examples are elevators, car doors, canopies etc. In the majority of these applications, friction is critical (e.g. the wire in a canopy should slide smoothly), and after a period of tuse, wear damage of the wire can also obstruct the performance.

Fast screening polymer coatings on cables

WHY

Various types of polymers can be used on steel cables, to provide a controlled-friction and noise-reducing coating when used on pulleys.  An efficient way to prescreen the behaviour of different types of polymers, in terms of frictional stability and durability, is needed.

How can we measure the stickiness of clay?

WHY

During the processing of bricks in the construction industry, clays slurries can adhere (stick) to mechanical components such as mixers, hindering their function. In addition, in the drilling industry severe damage of the drills can be caused by the sticking and swelling (due to water adsorption) of soils onto the drills. A methodology needs to be developed to measure the stickiness of clays/soils on metallic components.
