Remember from 2.001 that the following factors need to be known to calculate the stiffness of something. Typical configurations and their equations are listed below. This is an approximation of a simple truss, ingoring the cross members. There are some tools to help you calculation the amount of deflection in your structures. It also calculates the amount of delfection at a given point for a smiply supported and cantilevered beam.
P can be positive or negative.
The values of each force is displayed at the end of its force line. P can be positive or negative. The values of each force is displayed at the end of its force line. The plot may look like the beam is bending a lot, but compare at the scale on the x and y axis .
