2. If the scheme requires M parts, then in the warehouse they will be M-1.
3. The motor will not spin in the wrong direction.
4. The reliability system will disable other systems.
5. The device protected by a high-speed fuse will be able to protect this fuse by firing first.

Universal laws for young engineers, developed by the Committee of Practical Recommendations of the International Association of Engineers-Philosophers.
1. Any mistake that can sneak into any calculation will creep into it.
2. Any error in any calculation will be aimed at causing the greatest harm.
3. In any formula, constants (especially those taken from technical reference books) should be treated as variables.
4. The most accurate size on any diagram or drawing has the greatest chance of being missed.
5. If the test setup works flawlessly, all subsequent ones will be faulty.
6. The request for changes that absolutely need to be made to the device always comes after its manufacture is almost finished.
7. Parts that simply can not be collected incorrectly, yet will be collected incorrectly.
8. All terms of supply obligations should be multiplied by a factor of 2.0.
9. Technical parameters of the devices declared by the manufacturer should be multiplied by a factor of 0.5.
10. The expectations of buyers of the new car should be multiplied by a factor of 0.25.
11. Any device requiring adjustment and adjustment usually does not respond to either one.
12. If more than one person is responsible for an error in the calculation, you can not find the guilty.
13. The same devices, tested in the same way, will behave in a completely different way in operation.
