I am looking for theoretical and/or empirical information about the extent in which a mesh/screen/net made of some kind of wires is slowing down airflow thru it, comparing to air flowing around it. At this point I am interested in meshes starting at a scale of insects screens (about 1mm) and...

I am really grateful for all those answers! Well, changing the cleaning fluid seems really feasible. Two questions I would ask: First, do you think such material should be used under the "belt" to improve the conductance with the machine, or above the belt to improve the conductance with the...

Thanks Marcus! Well, this is a feasible idea. Actually I thought about something similar (without all the technical details, which are important), but the problem is that not many people would really like to use something like that. Many treadmills already have some kind of a strap that...

At the small gym I am working at there are about 12 treadmills. On some of them if you run for a few minutes and then touch the body of the treadmill you get a static electricity shocks. The machines are all properly grounded. At first, I thought the problem was that the body of the machine...
