Study Notes
Bicycle Maintenance
- Early bicycle models from 1898 are disliked due to their simple mechanism.
- Periodical inspection and attention to bearings and running gear are necessary to ensure satisfactory service.
- Riders who are unaware of their machine's construction and requirements may cause the bicycle to deteriorate prematurely.
Importance of Knowledge
- The phrase "Know thy wheel" emphasizes the importance of understanding the construction and requirements of a bicycle.
- Having this knowledge can simplify emergency repair, ensure a smooth-running wheel, reduce the chance of accidents, and extend the life of the machine.
Biology of the Lampyris
- The female Lampyris is a ground-bound, larval-shaped insect that knows nothing of flying.
- The male Lampyris is also imperfect until it reaches maturity after pairing.
- The Lampyris has an epidermis, is dark brown in color, and has pale pink markings on the thorax, especially on the lower surface.
- Each segment of the Lampyris has two spots of bright red color.
Habitat of the Lampyris
- The Lampyris frequents the edges of irrigating ditches with cool soil and varied vegetation.
- These ditches are a favorite haunt of the mollusc.
Aviation Engines
- The diagram in Fig. 1 shows the installation of a Gnome "Monosoupape" motor in a tractor biplane.
- Figs. 2 and 3 show other mountings of Gnome engines.
- The diagram in Fig. 4 shows how an Anzani Ten-Cylinder Radial Engine is installed to a plate securely attached to the front end of a tractor airplane fuselage.
Causes of Noisy Operation
- There are several power-plant derangements that can cause noisy operation.
- Knocking or rattling sounds can be caused by wear in connecting rods or main bearings.
- Carbon deposits in the cylinder heads or premature ignition due to advanced spark-time lever can also cause noisy operation.
- Squeaking sounds can indicate dry bearings, and oil should be applied to the parts immediately.
- Loose connecting rods or bearings can cause harm if not addressed promptly.
- Deterioration of the rubber hose in the flexible connections between the radiator and water manifolds can also cause noisy operation.
