I understand how, as engineering a specific project, limiting torque is very important. I have the interesting job of creating it. I have, over the years of calibrating torque and force, have seen some stuff that just plain scares me. Being as we are renovating the torque/force lab I really...

so is it realistic to be able to heat treat a 3/4" piece of steel to handle the force, or would it, even with the best possible tolerances, still fall short? (without exotic alloys) I agree about the forged steel being the best, but that may again, explain the "priceyness" of these adapters...

thanks for the link to formulas how does the hardness/heat treating effect things? I have some further info. on the adapter I have. (~1" x 1" x 2.375") good to at least 1000 ft lbs, being as it was used previous years to cal the standards. I threw it on the balance to get mass, and got...

What would be the way to determine where a piece of steel will yield to the torque? A formula would help, along with a bit of explanation as to how torque yield is calculated. Torque adapters from these companies can be very expensive. If the adapter is just a piece of steel heat...

This setup is a commercially purchased unit. (CDI inc.) We have some of these male to male units already. (1/2" square, 1/4" square) They are magnetic as a drillbit. (so probably not a weird alloy) Seems that it may be a hardened material, looking at the broken one. The 3/4" and 1" drives on...

Good afternoon all, As some of you may remember, I am a metrologist (of 35 years). Mainly physical stuff. Well, I have a new job at a great place doing pressure, force, torque, etc. My problem is: I need to connect "female to female" 3/4 square drive socket size. (I could used 1 inch...

many states also have "bridge laws" that limit the total gvw due to wheelbase. tag axles (the floater axles in between the drive and front axle) actually reduce the legal limit because the truck min wheel base is shorter. hence, put the tag behind and "have your cake and eat it two...

good morning all, I have been thinking about building a "blower" for a strange modified lawn mower based vehicle I built. What I was wondering about was using a smog pump. is there a simple formula that would tell me if the volume of air needed? I am also having trouble trying to find any...

good evening again, I have been rebuilding walls, hanging drywall, mudding, sanding(x5), painting, fab'ing and such since the last post, and I am finally getting to the stairs (whose butt I have kicked very well with hauling all the stuff upstairs) I still don't know what I am going to do...

good evening folks, Some of you will remember me from a couple years ago. I was laid off as a metrologist from GE after 15 years, due to down sizing, but that is another story (maybe for the lounge) anyway, I have a very unique home. It is made of 8 inch styrofoam blocks (think cheap...
