Abstract: The cantilever rectangular plates discussed previously ate all loaded continuously. Such as loaded uniformly or by a concentrated load at any point along the free edge.Let us now go a step further to deal with the case of discontinuous loading by taking a concentrated load at the middle of the plate for an illustrative example.For a numencal example, a square plate is taken.As it can expected, the deflected free edge y=a turns out to be almost a horizontal line, and the part of the free edge x=a from y=0.5 to y=a is deflected into an inclined straight line.Moreover, the total bending moment along the clamped edge checks very closely with the statically determined value from equilibrium,All these data conf irm our calculation.
