In my situation I will have a threaded rod suspended vertically with the load being supported by a nut at the bottom The rod is 18 8 with an 18 8 nut 1 4 20 Sorry I am not a mechanical engineer so if you could be specific on how the factors apply and where the numbers derive from I would appreciate it so I could solve this myself in the future a rod radius of 1 inch 2000 psi supplied to the base on extension and 2500 psi supplied to the rod end for retraction Extension Force 3 1416 x 2 2 x 2000 psi Extension Force 25 132 8 lbs Retraction Force Annulus x 2500 psi 2his calculator calculates the tensile stress area of a screw thread fastener Use this calculator for materials less than 100 000 psi ultimate tensile strength Tensile Thread Stress Area Equation and Calculator less than 100 ksi Standard ANSI Hardware Fastener2012 5 10 nbsp 0183 32 7 171 509 If the internal thread is deep enough to develop the full strength of the threaded rod screwed into it then the axial load is limited by the strength of the smaller diameter rod or the strength wall thickness of the threaded device sleeve Typically a 5 8 quot diameter bolt needs to have a minimum of 5 8 quot internal thread in the 2020 5 11 nbsp 0183 32 How is Clamp Force for a Bolt and Nut Assembly Calculated Clamp force is what holds a bolted joint together Published charts are available for determining clamp force but we ve found it s often useful to understand how these numbers are calculated

Example Calculate the friction force of a copper rod of 1 Kg being pushed from a stationary position on a steel surface In this case the object was not moving so it is static friction And from the static coefficient table the static coefficient for copper on steel is 0 53 2021 5 6 nbsp 0183 32 If we want to calculate tension at the bottom of the arc when it s highest we would first recognize that the tension due to gravity at this point is the same as when the weight was held motionless 98 Newtons To find the additional centripetal force we would solve2020 1 19 nbsp 0183 32 How do I calculate how much welding rod I need 1 Calculate the weld area cross section of the weld including root and cap reinforcement in square millimetres 2 Multiply weld area by pipe circumference weld length to give a weld volume in cubic millimetres 3 Divide this answer by 1 000 000 000 to give weld volume in cubic metres Hydraulic cylinder force calculator The cylinder force F is dependent on the operating pressure p and the effective area A F p 195 A The force produced on the opposite of rod side The calculated equation F p 215 πD 2 4 Pressure p Piston diameter D The force 2008 5 11 nbsp 0183 32 Friction is by far the most important factor here Were it not for friction the force exerted by that screw would be tremendous 200 pounds of force exerted at a 1 foot radius one complete revolution would be 1 x 2 x 3 1416 6 2832 travel 200 pounds force over that distance would be 1256 64 foot pounds of work
