I recall a transmission test stand for Allison transmission, I worked on years ago. We had shear pins that would break before the flange .... made it easier to replace. Thanks for sharing ! Good stuff.
Yes, thanks. It is really informative. I am researching so that I can fabricate my own as it is too expensive to buy one. At least, I haven't found one cheap enough
alloy car rim. magnets. eddy currents. permanent magnets require a load cell, a pivot, and some way of varying the gap or flux strength. electromagnets need a variable power supply and can be calibrated so excitation voltage gives a direct reading... no load cells.
water has a high thermal capacity, higher than oil. water when its in contact with a surface limits the maximum temperature to 100C... it has to boil and evaporate for the temperature to exceed that. oil starts burning and stinks. and catches on fire. and makes a mess when theres a leak.
@@davesstillhere Wrong answer. I better go tell the company I work for that has been making air dynamoneters for the last 25 years that they don't work.
Steve is the best! Great info.

Me too. The load cell and instrumentation are what I expect to give me the most trouble, not being a computer guy.

Do you have am email I have some questions about a stuska xs-111 brake?
Why water instead of a 10w oil?

Why not just use air instead of water? Basically the same principle but you don't have to deal with water/plumbing issues.
Air compresses, water doesn't. Air wouldn't provide a load.

Really? I never heard of such a thing. Could you post a link to an article? I'd like to read up on it
Driveshaft through the roof! When your dyno throws parts, talk to Steve....
