How to specify gas struts accurately | Engineer Live
WEBMar 28, 2019 · 2.04 Opening Force Calculation. The force required to hold the lid open (F1) can be calculated using the formula: Gas Spring Force (F1) = Mass of lid x Centre of Gravity / Radius of Force x Number of Springs. Closing Force Calculation. Similarly, the force required to close the lid (F2) can be calculated using the formula: Closing Force F2 ...
The hole story: the benefits of drill and blast - Engineer Live
WEBApr 21, 2016 · Ideally, most coal mines want to have a small amount of hard toe by standing off the coal by a small amount. This protects the coal seam during the blast, avoiding dilution of the overburden material with the coal seam. Drilling to elevation is also important when the blast design requires a level bench as a result.
An Expert Guide To Sonic Drilling - Engineer Live
WEBMay 1, 2020 · Sonic drilling is a more efficient method of drilling by using high-frequency resonance to create a smoother path of travel for the drill by reducing or even eliminating any frictional resistance from subsurface materials being encountered. The high frequency resonance results in a vibrating head that is being both pushed up and down by the ...

Wear of rolling bearings: signs, causes and remedies
WEBApr 14, 2015 · Abrasive wear of rolling bearings, often referred to as ‘three-element’ wear, is the removal of material from three main areas of a rolling bearing: the raceways, the end faces of the rolling elements, and the ribs/cages. Abrasive wear normally takes the form of a high lustre (ie semi-glossy) finish with a mirror-like surface structure.

The Evolution Of Cemented Carbides | Engineer Live
WEBAug 15, 2022 · Extremely Durable, Yet 3D-Printable. Most cemented carbides use a cobalt binder phase. But due to their limited corrosion resistance and their being prone to binder leaching, pure WC-Co carbides are often not suitable for application fields where corrosion is likely to occur. The only solution is to use materials such as Co/Cr, Co/Ni or Ni/Cr ...
