Friction Engineering To calculate the reaction forces, we can use the following steps: Fy = 0 Structural Shapes Therefore, engineers aim to limit deflection to acceptable levels so that the structure performs satisfactorily and provides a comfortable environment for the users. Please note that most of the calculators do require a premium membership for full functionality. Figure 810 Approximate resultant applied force and reaction forces on the plate The deflection plot in Figure 86 shows that the deflection curvature . The formulas show that the stiffer the beam is, the smaller its deflection will be. Deflections are assumed to be very small compared to the overall length of the beam. Our calculator is easy and simple to use. Per. How to Calculate Beam Deflection. This is insanely useful! I also recommend Mitcalc.com see link 1 Circular Plate , uniform load , edges clamped . The plate is flat, of uniform thickness, and of homogeneous isotropic material; the thickness is not more than about one quarterof the least transverse dimension, and the maximum deflection, all forces, loads and reactions are normal to the plane of the plate; and, the plate is nowhere stressed beyond the elastic limit. We also highly recommend specifying the different load cases each load corresponds. I would recommend that for more comprehensive calculations including greater detail with more accuracy standard reference texts are used e.g Roarks book. Circular Plate , uniform load , edges simply supported .
