Screw thread Calculations - Roy Mech

Following are equations to provide more accurate evaluation of the shear strength of threads. These are equations derived from FED-STD-H28/2B, 1991 and Machinerys Handbook eighteenth Edition. They strictly apply to UN thread series but if the relevent metric screw thread dimensions are used they will give reasonable results.

mechanical engineering - Calculation of Clamping force ...

The questioner's formula is erroneous because it doesn't include the important effect of the screw thread. The "K" in that equation should include friction as well as the helical angle of the screw. I believe this simple form of the equation started with the accompaniment of a figure or chart to look up a suitable value for K, and then it got ...

Quick Design Guide for Screw Piles and Helical Anchors

Note: In compression, the full cross sectional area of the helical plate is used and there is no reduction of shear strength for installation disturbance. Equation 1.2 indicates that the ultimate undrained compression capacity of a single-helix screw-pile increases linearly with the increase in undrained shear strength.

How to Calculate Bolt Positions for a Bolt Circle Pattern

The distance formula for n bolts placed on a circle with a diameter of d is. Distance = d *sin (360/ (2 n )) = d *sin (180/ n) Be sure to set your calculator to degree mode, rather than radians, when using this formula. Example: if a bolt circle has a diameter of 50 cm and 8 bolts spaced evenly around the circumference, then the distance ...

Chapter 9: Column Analysis and Design

A = cross-sectional area of the column (in2) P actual = actual load on the column (pounds or kips) F a = allowable compressive stress per code (psi or ksi) • This stress equation can be rewritten into a design form to determine the required short column size when the load and allowable material strength are known. A required = P actual /F a

Bolt Pattern Force Distribution - MechaniCalc

If the bolt areas are the same, the equation above simplifies to P z.FZ = F c.z/n, where n is the number of bolts in the pattern. The axial forces on a bolt due to moments about X- and Y- axes are calculated as: axial force on bolt due to MX …
