This interface allows you to design a bridge by adding and customizing beams and cables. Each component's properties (length, width/thickness, and material) affect the bridge's structural integrity and cost. Structural Integrity: This represents the overall strength of your bridge design. It's calculated based on the properties and materials of each component. A higher percentage indicates a stronger bridge. Cost: This is the estimated cost of your bridge in Indian Rupees. It's calculated based on the amount of material used and the type of material chosen for each component. Performance History: This graph shows how your changes affect the structural integrity and cost over time. Use this to optimize your design for the best balance of strength and cost.
