Displacement Field by Point Forces

This lecture covers the concept of solving the displacement field caused by point forces using Green's functions. The instructor explains the underlying problem, the solution for a single unit body force, and the integration process to obtain the total solution. The lecture also delves into the concept of the Green's function and its application in solving displacement caused by point forces. Various equations and derivations are presented to illustrate the process of finding the displacement field. The lecture emphasizes the importance of understanding the continuous distribution of body forces and the significance of equilibrium problems in determining the total effect of forces.
