Compression forging analysis
WebWhen the load on a fastener group is eccentric, the first task is to find the centroid of the group. In many cases the pattern will be symmetrical, as shown in figure 28. The next step is to divide the load R by the number of fasteners n to get the direct shear load P c (fig. 29 (a)). Next, find Σ r n2 for the group of fasteners, where r n is ...
