Explanation:

A Bourdon tube is a type of pressure gauge element commonly used for measuring pressure. The maximum pressure that a Bourdon tube can measure depends on its design and material. However, based on the options provided:

  1. 10 MN/m² (megapascals): This is a high pressure and may be beyond the typical range for Bourdon tubes. Bourdon tubes are often used for moderate pressure measurements.

  2. 5 MN/m²: This is also a high pressure, and while some Bourdon tubes can handle pressures in this range, it depends on the specific design and construction.

  3. 3 MN/m²: This is a more moderate pressure and falls within the typical range for Bourdon tube applications.

  4. 8 MN/m²: This is a high pressure and may be at the upper end of the typical range for Bourdon tubes.
