I have a bridge design project with the following details (in the pic). I really need some help with this, at least raw idea.

Assessment Details The purpose of this project is to analyze the loading conditions of a simple bridge and redesign the bridge such that it can bear the loading requirements stipulated below. Since ancient times, bridge building is an important capacity for civilizations to thrive. Bridges allow humans and animals to travel over dangerous terrains such as ravines, chasm, and rivers. Indeed, many civilizations from antiquity had been able to build many bridges that last for thousands of years, which remain even after their civilization had collapsed into the pages of history. With modern scientific knowledge of stress analysis, together with other engineering technologies, humans are now able to build bridges across large distances and survive extreme weather while bearing tremendous loads. These engineering marvels, such as the Golden Gate Bridge, are a testament to human ingenuity and perseverance. As you have gained sufficient knowledge about Stress Analysis from this class, it is time to put your knowledge to the test. In this project, you are provided a bridge deck (600 X 100 X 3 mm) made from PMMA, aka Acrylic (Material Specification 2). You are to build a complete bridge that satisfies the following conditions: 1. The bridge shall span a chasm that measures 500 mm from one edge to the other. 2. The bridge shall be made entirely of Acrylic and held together by glue. No mechanical fastener shall be allowed. 3. The bridge shall have guard rails and allow for 1 way traffic. The traffic will be for 2 PAScars (link 2). 4. The combined load of these PAScars shall be 10 kg maximum. The bridge's allowable stress is recommended to have a tensile safety factor of 1.5 when under this load. 5. The bridge shall not be damaged or disintegrated in any way as the PAScars travel through it (multiple times). 6. The maximum deflection point on the bridge shall not be more than 5 mm as the PAScars travel through it (multiple times). 7. The bridge shall connect seamlessly into the 1.2 meters PASCO dynamics track (link 2) at both ends. 8. The bridge shall only be supported at its 2 ends. Your team will provide the mean of support. No human contact shall be permitted. To strengthen the bridge deck, you may want to furnish extra parts to modify its cross-section. For this purpose, you are authorized to use the Laser Cutter in our Advanced Manufacturing Workshop to cut the appropriate parts according to your design. Please note the following restrictions: 1. The only stock available for this project is Acrylic with 3 mm thickness. 2. Each team is allocated up to 0.3 m2 (or 3000 cm2) of material, not counting the bridge deck provided initially. Each extra 600 cm2 means a deduction of 5% on your total grade for the project. 3. You can submit a fabrication request by sending an email to the lecturer (Mr. Trung Nguyen, trung.nguyenchi@rmit.edu.vn) to declare your intentions. The email should include a Bill of Materials which contains the part names, description, surface area, and desired quantities. The part designs shall be captured in a .dxf file. You may use Solidworks, AutoCAD, or other CAD software to draft the designs. The drawing unit must be millimeters. If possible, please include an exploded drawing of the bridge design for better examination and feedback. 4. Your team is responsible for assembling the parts into the bridge deck. You are free to use any glue you can procure. 5. The deadline for submitting a fabrication request is [To be updated].
