• How do you convert Ft/Lbs of Torque? To convert ft/lbs of torque to in/lbs and Nm, use the equations: Inch Pounds (in/lbs) = ft/lbs x 12. Newton Meters (Nm) = ft/lbs x 1.3558.

Relating Bolt Torque to Bolt Tension From the power screw equations, Eqs. (8–5) and (8–6), we get Applying tanl = l/pd m, Assuming a washer face diameter of 1.5d, the collar diameter is d c = (d + 1.5d)/2 = 1.25d, giving Shigley’s Mechanical Engineering Design Torque Formula from data in chart I have attached example worksheet, which includes a calculation "VBTO" right now as 1011 for a 3"-600 Valve. However, I need to use a formula which determines which table array to pull data from (either 600 or 900) since the values are different between the two.

Jul 27, 2011 · ft= 0.75. Wt= 2.00. The values of Puand Paare the LRFD and ASD factored loads, respectively, applied to the member. Nominal Bolt Bearing Strength, Rn: The nominal resistance, Rn, of a single hole is the minimum value of the two limit states: tear out and bearing deformation. Calculating reactions at supports is always the first step in analyzing a beam structure, and it is generally the easiest. It involves calculating the reaction forces at the supports (supports A and B in the below example) due to the forces acting on the beam. You will need to know this to progress through and CALCULATIONS: Angle q = Using Table XVIII from AISC 9th Ed. Manual (ASD) - page 4-69 P = A = ... "BOLTGRP" is a spreadsheet program written in MS-Excel for the purpose of analysis of bolt groups using and a maximum of either 25 or 75 bolts for a bolt group. ... Bolt Size, in.

Torque in Ft/Lbs per inch of bolt/stud diameter To estimate the stud torque required for a 3,800 psi gland load, multiply the gland stud diameter by the number shown in the table that corresponds to the stud size and stem diametre. Note: A 3,800 psi gland load may not be suitable for all types of packing. Australian Pipeline Valve

By Steven Holzner . You can use physics to calculate the amount of torque needed to accelerate (or decelerate) the speed of a spinning disc. Without the ability to change the speed of a disc, it would be impossible for you to watch a movie on your DVD player. A simple formula of the moment of inertia of any object, be it a point mass or a 3D-structure, is given by: where ‘dm’ is the mass of an infinitesimally small part of the body

Mar 26, 2020 · For the past 40 years, when the oil and gas industry thought of bolt lubricant, it focused on disassembly — i.e. the breakout torque seen at the bolt head or at the nut of the fastener. What went unexplored until recently was how lubricant affects the Nut Factor on a fastener, which then affects tightening torque, and therefore effects the ... When tightening a bolt or nut, the applied torque must overcome the thread friction, the friction under the bolt head or nut and the inclined plane of the thread, to obtain a bolt preload (see Fig. 1A). While untightening, provided that the assembly remains in the same condition, the applied torque only has to overcome frictional forces.

For a reasonable factor of safety, the industry accepted value to use for bolt rating in the formula above is 75% of the proof load. Cross-Sectional Area The cross-sectional area for the threaded portion of the bolt (often referred to as the stress area) is calculated using a formula that accounts for the specific diameter and thread pitch.See Torque Force Design Equations webpage and torque chart page for recommended fastener torque and equation data.. This fastener bolt torque calculator will Estimate the unknown torque, diameter, axial force applied and coefficient of turning friction for the given conditions.

The calculation method takes into account the elasticity of the connected shell, the thermal expansion between flange and bolts and the effective gasket surface and calculates the required assembly torque for the bolts. In order to evaluate the load cases, the loads for flange, bolts, gasket and loose flange are determined.The following design resources are for design screws and bolts for the proper torque, stress, strain, preload and other engineering critical design parameters.
