442 - How do engineers test and improve machine designs?

Engineers test and improve machine designs by following these steps:

1. Draw and simulate: They create a digital model of the machine and use computer simulations to see how it will work.
2. Build a prototype: They make a real-life model of the machine to test its parts and how they work together.
3. Test and measure: They try out the machine and measure how well it works, looking at things like speed, power, and efficiency.
4. Find and fix problems: They identify any issues or weaknesses and make changes to fix them.
5. Repeat and refine: They test and improve the machine again and again until it meets their goals.

By doing this, engineers can make sure their machine designs are safe, efficient, and effective.
