This is very useful information for many purposes, especially for roof framing - the slope, sometimes called pitch, is calibrated on speed squares. Axisymmetric Finite Deflection of Circular Plates. Two different types of boundary conditions are con- sidered for annular plates. First of all the maximum deflection (translation) of the plate will be calculated at its center and then the bending moments in the plate will be presented. The chance of shot deflection not only depends on the angle of the armor, however, but also on the shot. I felt a good starting place once the amount of pressure was known is to calculate the deflection of a 1/4" plate 45" long supported only at the ends. 2nd MOMENT of AREA. Later, the theory of elasticity was extended as there were many researchers working on the plate and the extended plate theory was formulated.
