Limits and fits refer to the tolerance and clearance between mating parts, ensuring that components can fit together properly and function as intended. Proper limits and fits allow for the correct function of a mechanical system and ensure the interchangeability of parts.
- Aesthetic appeal is not related to limits and fits, as these are functional considerations.
- Proper function and interchangeability is correct, as this is the primary purpose of limits and fits in engineering design. They ensure that parts fit together within prescribed tolerances, allowing for efficient operation and interchangeability.
- Heat transfer is not directly related to limits and fits, although it may be affected by tolerances in some cases.
- Colour coding has no relation to the mechanical concept of limits and fits.
Thus, limits and fits ensure proper function and interchangeability.
