ABSTRACT

While diaphragms are mostly used in the axial-loading mode, there are situations where diaphragms must be able to withstand transverse or torsional moments. In some instances, they are used as shown in Fig. 16.1 where a bending moment is applied to the rigid center of the diaphragm as is the case for a flexural pivot designed in some instruments. A flat diaphragm with a rigid center when subjected to a torsional moment, as shown, will endure not only torsional moments in the radial and tangential directions but also bending moments and transverse forces.
