Question
You are employed as a mechanical software engineer within an electricity transmission company, specializing in
the development of new electricity transmission towers. Your division is responsible for offering computer-
based modeling and design solutions utilizing Finite Element Method (FEM) principles. Your primary
responsibilities encompass tower analysis and the identification of optimal materials to fulfill specified criteria.
Under the guidance of your immediate supervisor, you have been assigned distinct responsibilities within an
ongoing project. In your capacity as a member of the design team, you are tasked with constructing an
appropriate model and executing a sequence of simulation iterations to explore and enhance the tower's
performance. The outcomes of these simulations will guide the decision-making process of your team's director
in terms of the final design. Reference to Figure 1 provides a visualization of the electricity transmission to wer
under consideration.
