We typically do not use a mesh pad at all, but all of the...
If you want to do a bit more math and get what some of my profs* believed to be a more accurate answer, try checking in a mechanics of materials textbook. A good one is Intermediate mechanics of Materials by Vable. There are definitely ways to approach the problem that will get you closer than...
I was asked to make sure that a swing check used in a project could handle working pressure of 70 psi and flow rate of 65 GPM. The manufacturer gives me a pressure rating of 200 psi for water. Sounds dandy.
However, if that swing check closes, flow rate becomes zero and the pressure pushing...
Fun thread.
Bicycle spokes were brought up earlier as an exception to the odd better than even thing. These are paired evenly because each spoke on the left side of the wheel is paired with one on the right side of the wheel, so that you can adjust the tension on each side in the vicinity of...
