Abstract: The cantilever rectangular plates discussed previously ate all loaded continuously. For example, the load may be either a uniform or a concentrated load at the free edge of the plate. Now we go a step further to deal with the case of a discontinuously loaded rectangular cantilever plate. The problem to be solved Will involve a concentrated load at the center of the plate, as shown in Fig. 1. The method of solution used is the same as before.
