This document analyzes the stress and deflection of a cantilever beam under different loading conditions using analytical calculations and finite element analysis in ANSYS. Analytical calculations are performed for three cases: a point load at the free end, uniform distributed load, and uniform varying load. Computational analysis using 8-node brick and 10-node tetrahedral elements in ANSYS is conducted for the same cases. Results show that the 10-node tetrahedral element more accurately calculates deflection while the 8-node brick element better calculates stresses when compared to analytical solutions.
