Have you at any time puzzled how several threads a nut desires to be secure? [Hydraulic Press Channel] determined to obtain out, employing some significant hardware and a hydraulic push. The system was very simple. He took a conventional nut and minimize the heart out of it to have nuts with less threads than the comprehensive nut. Then it was on to the hydraulic press.
As you may well expect, a solitary-thread nut gave way fairly quickly at about 10,000 kg. Adding threads, of class, will help. No genuine surprise, but it is good to see true characterization with serious numbers. It is also attention-grabbing to enjoy metal hardware bend like cardboard at these tremendous pressures.
In the finish, he eliminated threads from the bolts to get a much better check and acquired some stunning effects. Inspecting the failure modes is also appealing.
Honestly, we are not guaranteed how valid some of the outcomes were, but it was interesting looking at the thread stripping and the catastrophic failures of the samples in the push. It appears to be like to do this appropriate, you have to have to try a wide range of assemblies and perhaps even use distinct components to see if all the data fit with the modify in the variety of threads. We hope the condition of the threads also makes a variation.
Nonetheless, an fascinating online video. We generally get pleasure from observing info created to test theories and assumptions. We think of bolts and issues as very straightforward, but there’s a stunning amount of money of technological know-how that goes into their style and design.
