- Chapter 5: Physics for Aviation › Gas Laws › General Gas Law
General Gas Law By combining Boyle’s and Charles’ laws, a single expression can be derived which states all the information contained in both. The formula which is used to express the general gas law is as follows: = Temperature ... Temperature Pressure 2 (Volume 2) Pressure 1 (Volume 1) When using the general gas law formula, temperature and pressure must be in the absolute. Example: 20 ft3 of the gas argon is compressed to 15 ft3. The gas starts…
- Chapter 4: Aircraft Metal Structural Repair › Compression
Compression Compression, the stress that resists a crushing force, tends to shorten or squeeze aircraft parts. The compressive strength of a material is also measured in psi. Under a compressive load, an undrilled member is stronger than an identical member ... However, if a plug of equivalent or stronger material is fitted tightly in a drilled member, it transfers compressive loads across the hole, and the member carries approximately as large a load as if the hole were not there. Thus…
- Chapter 5: Aircraft Welding › Gas Metal Arc Welding (GMAW)
Gas Metal Arc Welding (GMAW) Gas metal arc welding (GMAW) was formerly called metal inert gas (MIG) welding. It is an improvement over stick welding because an uncoated wire electrode is fed into and through the torch and an inert ... gas, such as argon, helium, or carbon dioxide, flows out around the wire to protect the puddle from oxygen. The power supply is connected to the torch and the work, and the arc produces the intense heat needed to melt…
