This document describes a beam deflection simulation using ANSYS software. It involves modeling a beam with given properties subjected to a 100 lb force at one end, with the other end fixed. The simulation is performed using 4 node beam elements and linear elastic material properties. The results show the deformed beam shape and lists the displacement of node 4 in the y-direction, which indicates the deflection of the beam tip under the applied load.
