Math can be tough, but with a little practice, anyone can master it. Once the tensile capacity (or strength) of the material is assessed, engineers will typically calculate the applied stress in the component. I was wondering how the tensilestrength of the bolt related to the thread strength. Im looking for a simple steal tensile strength calculator for metal tubing/axles. Tensile strength values vary for various steel densities. However, the limiting factor will be the material it is screwed into, and the wood will typically yield before the lag bolt will, so you may have a problem using only one lag bolt. how can i compute the 8-1/2 diameter steel to find the ultimate yield and tensile strength? @Vani- Apologies, but that is not something we are able to help with. Ultimate tensile strength formula: max = Pmax /A0 where A0 = original cross sectional area, Pmax = maximum load This value is usually much higher than the yield stress (as much as 50 to 60 percent more than the yield for some types of metals). Hi, Take that value and multiply it by 60% (0.60). What is tensile strength? That linear dependence of displacement upon the stretching force is called Hooke's law and can be expressed as, Fs = -k dL (4). For an example, lets use normal draft. Ultimate tensile strength is often shortened to tensile strength or even to the ultimate.. The specimen is held on opposite ends using clamps.
