In today’s world, engineers typically need zero physical attempts to build a bridge that stands successfully. This is because they don’t construct the bridge blindly or by trial and error. Instead, they use advanced software tools like AutoCAD and other architectural and structural design programs to plan every detail with precision. With the increasing power of computers, engineers can run detailed simulations, test various stress conditions, and optimize the design before a single piece of material is used. As a result, when the bridge is finally constructed in the real world, it is highly unlikely to collapse—because all potential failures have already been identified and resolved during the virtual design phase.
