Physics Setup

In this video we will assign a material to the I-beam.

In this video we will assign a support and a force to the I-beam. 

The reason behind applying the load to the central web is to focus on the deflection that occurs across the entire span of the I-Beam.  This tutorial isn't concerned with the deflections that occur to the top and bottom flanges. The problem focuses on the increasing impact which shear deflection has on shorter, non-slender beams.  This shear causes a difference between the analytical Euler-Bernoulli solution and the 3D finite element model.
