MACHINERY AND EQUIPMENT SAFETY AN INTRODUCTION 3 1.1 mecHanIcal Hazards Machines have moving parts. The action of moving parts may have sufficient force in motion to cause injury to people. When reviewing machinery and equipment for possible mechanical hazards, consider: • machinery and equipment with moving parts that can be reached by
Chronocentric: Accuracy of Fine Wristwatches
The good news is that the actual variations of a mechanical watch will often cancel each other out. This means a mechanical watch will tend to be more accurate over a longer period than the single day COSC measurement may imply. The day to day performance of quartz is much more consistent than mechanical under identical conditions.

Quality 101: Surface Analysis: Beyond Roughness
Most discussions on the quality of surface finish revolve around the measure of roughness. Indeed, roughness is the most common measure of surface finish, and parameters such as average roughness (Ra) and mean roughness depth (Rz) are the most commonly specified. But the ways to measure a surface and the reasons for doing so go far beyond roughness.

3D printing with a smaller nozzle diameter
3D printing with a smaller nozzle diameter For sure, a smaller nozzle produces finer details, yet! Faster movement always induces more mechanical noise, due to higher inertia and belt sloppiness for example, to the point that it ruins the purpose of having a smaller nozzle to achieve a higher quality in the first place! I will switch

Losses in Steam Turbines ~ ME Mechanical
Losses in moving blades are caused by various factors as enumerated below: Impingement Losses: Steam issuing out from the nozzles meets the leading edges of the blades and energy may be lost if the entry is not smooth enough and eddies are formed. Frictional Losses: Steam encounters these losses in the blade passages, which depends on the roughness of the blade surface.
