430 - How do engineers design safe and efficient machines?

Engineers design safe and efficient machines by following a step-by-step process. Here's how they do it:

1. Define the problem: They figure out what they want the machine to do and what problems it might solve.
2. Research and drawing: They research and draw rough sketches of the machine, considering its size, shape, and parts.
3. Design models: They create detailed models of the machine using computer software.
4. Test and simulate: They simulate how the machine will work using computers or small-scale models to identify potential problems.
5. Prototyping: They build a small-scale prototype to test if it works as planned.
6. Testing and refining: They test the machine and make changes to make it safer and more efficient.
7. Making adjustments: They fine-tune the design to meet the required standards and regulations.

By following these steps, engineers can create safe and efficient machines that work well and help people.
