Not illustrated. 1910 Excerpt: ...(1) Shearing Stresses.--The shearing stresses on a pin are found, as in any beam, by summing up the forces acting on one side of any given section. In dealing with pins it is convenient to resolve all forces into horizontal and vertical components and then to sum up the components separately and get the resultant where desired. The shearing stress is calculated as in rivets, as the average stress on the entire cross-section, and the allowed unit (12,000 lbs. per sq. in. in the Specifications, Art. 18) is applied in the same way. It is seldom that the shearing stresses will determine the pin size. (2) Bending Moments.--The bending moments are generally calculated by assuming the loads as concentrated loads, applied at the centres of bearing of the several members. This gives slightly larger values for moments than if the loads are assumed as distributed over the areas of contact, and sometimes it is specified that the loads may be assumed as distributed over one-half the widths of the bearings. The difference in result is small, however, and the former method is sufficiently accurate. In the calculation of moments the arrangement of the members on the pin is first tentatively fixed upon, such arrangement being made with particular reference to maintaining small bending moments. The moments are then calculated for the critical sections, as may be determined from inspection or by trial. The horizontal and vertical components of the forces are separately considered and the resultant moment at any section found by the formula M = V M + MfJ, where M = total moment and Mh and M, are, respectively, the moments from the horizontal and the vertical components. The forces to be assumed in the calculation of shear and moments are not, in general, the maximum stresses i...
