This relationship is represented by the formula below: Threads per inch are 8 Mechanical Engineering. Unlike tensile and yield strengths, there are no published shear strength values or requirements for ASTM specifications. @Z- We can calculate the tensile, yield, or shear strength, but to me it sounds like youd be more concerned with the bar bending. Ultimate tensile strength is often shortened to tensile strength or even to the ultimate.. A 3/4 lag bolt, made to ASTM A307A would have an ultimate tensile strength of 14,874lbf, so it would support the weight by itself. @Matt from a bolt strength standpoint, anything 1/4 diameter or larger would support the weight.

Apologies. and probably a few more I havent thought of . WebSuppose the diameter and length of rod are and 36 inches. Ultimate load = 420 x area of c\s. I have seen literature that suggests a FoS of 8.5, although in engineering, FoSs of 2 5 are more common. @Ade- We are sorry, but we are not familiar with BS3692, so are unable to be 100% certain. In layman's terms, it is the measurement of the force required to stretch a material until it breaks. WebThe ultimate tensile strength of a material is calculated by dividing the area of the material tested (the cross section) by the stress placed on the material, generally expressed in terms of pounds or tons per square inch of material. If it is a large swinging or bouncing load, get an engineer to look at it. However, with the addition of a compressible gasket, we cant be sure if those charts apply as they are for steel to steel connections only. It is available for purchase through the AISC website.
