Ultimate tensile strength Generally, Steel, Titanium, Tungsten and Inconel are considered the strongest four metals. This formula will give you the ultimate yield strength of that size and grade of bolt. As I understand it, in simplist terms, tensile strength is the force required to pull a bolt apart and yeild is the force required to deform it to the point where it does not fully recover. Load (lbs) This is the force applied to your tube. How to calculate This corresponds to the maximum stress sustained by a structure in tension. Pls how to calculate area of a tensile bar with diameter 24.25mm and gauge length of 53.100mm. A36 is the most common thing you'll find at a steel yard. Unit Conversion Calculator Converter Ultimate load = 420 x area of c\s. I never realized that the bolt would fail before the thread, with sufficient engagement and a female thread of equal strength. If it is engaged less, then it is possible that the assembly will fail (probably through nut stripping) before the ultimate tensile is achieved. Would this be an indication of poor quality control during production?

Thanks, Jeff. I, of course, will be gripping the bar with both hands, but would like to know what the possible breaking point may be if I only had one lever/one hand on the bar. @Raymond Apologies, but we dont have the strength data for those two posts. Nut size is 2 15/16 heavy hex WebTensile or any other strength is simply maximum stress before the failure. It is important to understand that this value is only an estimate. That gives you the minimum ultimate breaking strength of 3/4 A36/F1554g36. That will tell you how many bolts are needed to support the load + safety factor. Tensile Stress Formula If the force is acting perpendicular to the surface is given by F, and the surface area is H, then tensile stress (T) is given by: T = F H S.I.
