Interesting/Cool Scaling Mechanism Designs

This "high static pressure" fan was able to create a static delta P of .002 PSI when dead-headed.

The strongest axial fan that EBM Pabst makes produces a maximum back pressure of 310 Pa = 0.044 PSI = 0.00306 Atm. It is not FRC legal (24.7" dia., 52.6 lb, requires 277 Vac @ 8.18 A). At work, we measure the effectiveness of the cooling fans installed in our equipment using an anemometer not a pressure meter.

I love (but really hate) how this thread has derailed from the coolest climbing mechanisms to banter over one guy's pedantic ridiculousness. If we really want to get into math and definitions from a dictionary in the name of legality, shouldn't we start a new thread? There are 2 weeks of new mechanisms yet to debut and I'd love for them to have a home to chit-chat about.

I hope after this coming weekend our team will be able to present our design, our team caded and built it in about 7 days of work. We tested it on an old robot and got it to work almost perfect just struggling on getting the back of the robot up the extra two inches needed because of the sag. We are bringing it to our event with our withholding allowance and gonna give it a shot. we have some ideas t solve the problem
