The distribution of forces and moments over a bolt pattern is similar to the analysis of a beam or a shaft. Applied loads are translated to the centroid of the pattern (analogous to the neutral axis of a beam or shaft). The forces and moments at the centroid are then resolved into axial and shear forces acting at the … See more The same properties that are required when analyzing a beam or a shaft are also required when distributing forces over a bolt pattern. It should be noted that the equations presented … See more As discussed previously, all applied forces and moments are translated to the centroid of the bolt pattern. As indicated in the figure below, any number of forces can be applied to the bolt pattern at any location.
