[最も好ましい] torsional yield strength formula 290448-What is torsional equation
In solid mechanics , torsion is the twisting of an object due to an applied torque It is expressed in newton meters(N·m) or footpound force (ft·lbf) In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radiusTorsional values for doubleshouldered connections (HT, XT and GPDS) were calculated per a modified form of the equation in API RP7G, Latest Edition Makeup torque values are based on the lower of 60% of the tool joint torsional yield strength or the calculated T3 value 2 1 7/ 8 1 3/ 4 1 1/ 2 1 3/ 8 1 1/ 4 2 1/ 8 2 1 7/ 8 1 7/ 8 1 3/ 4 These tables are for reference onlyThe general formula of torsional stiffness of bars of noncircular section are as shown below the factor J' is dependent of the dimensions of the section and some typical values are shown below For the circular section J' = J Shaft Torsion Stress Calculator And Equations Engineers Edge What is torsional equation
