However, the tables below cover most of the common cases. Such beams are said to be statically determinate since the reactions can be obtained from the equations of equilibrium. This tutorial explains how to use tables to quickly solve method of superposition slopedeflection problems for statically determinate beams. The deflection of the beam towards a particular direction when force is applied on it is called beam deflection.
