Per. deflection and stress for cantilever or simply supported beams. All loads and moments can be of both upwards or downward direction in magnitude, which should be able to account for most common beam analysis situations. The moment of inertia values we obtained tell us that the beam is harder to bend with a vertical load and easier to bend if subjected to a horizontal lateral load. This includes calculating the reactions for a cantilever beam, which has a bending moment reaction as well as x,y reaction forces. Additionally, in real-world scenarios, the beam may also experience other loads and forces such as shear, bending moment, and deflection, which need to be considered in the analysis and design. Loads can be in the form of a single-point load, linear pressure, or moment load.
