Please perform the tip capacity calculation two ways: For the first approach, assume that the total vertical stress at the pile tip is balanced by the weight of the pile. For the second approach, assume that the total vertical stress at the pile tip is not balanced by the weight of the pile (which means you need to include the vertical total stress term). Please compare your answers from these two analyses, examine some of your intermediate-stage calculation results such as the total overburden stress at the pile tip relative to the weight of the pile, and discuss whether or not the commonly used assumption about the total vertical stress at the pile tip is a…arrow_forwardA6.2- Given a simply supported beam with the typical cross-section as shown in the figure below.
