OMG THANK YOU SO MUCH
You're welcome!
1. The item that is part of a car's structural subsystem is A. frame. To identify this, you could refer to your knowledge of car components or consult car manuals, technical specifications, or engineering resources to learn about the different subsystems of a car and their components.
2. If a truck's propulsion system were removed, the correct answer is D. It could not move. To determine this, you could consider the function of a propulsion system, which is responsible for providing the necessary power to move the vehicle. Without it, the truck would not be able to move on its own.
3. Steel bars that make up trusses in a truss bridge should be arranged in A. a triangular shape. This configuration offers structural stability and can effectively distribute the load across multiple bars. You can determine this by studying bridge engineering principles, consulting bridge design resources, or referring to engineering guidelines for truss construction.
4. The best way to build a beam bridge that spans 500 feet (152 meters) is A. to link two or more beams end-to-end so the bridge does not sag in the middle. This method is commonly used to construct long-span beam bridges. To reach this answer, you could consider the engineering principles for beam bridge construction, consult bridge design resources, or analyze similar existing bridges.
5. Drones are used to help natural disaster relief efforts in various ways, but the most suitable answer would be A. to gather information. Drones can be equipped with cameras and sensors to collect vital information about disaster-affected areas, such as damage assessment, search and rescue operations, and situational awareness. You can verify this by researching the applications of drones in natural disaster response and humanitarian aid efforts or consulting relevant resources in disaster management.
