What is the main advantage of a Teflon hose?. Its sharp bending radius. Ability to withstand extreme heat. Ligthweight. High strength to weight ratio.

What is a Jo-Bolt?. A bimetallic, one piece fastener. A two piece fastener with a threaded shank and nut. A three piece fastener. A two piece fastener with a shell and mandrel or pulling head.

What is the minimum edge distance for rivet installation?. 2D. 4D. 5D. 3D.

How is rivet diameter determined?. Three times the thickness of the thickest sheet. Three times the thickness of the sheet. One and one-half times the thickness of the thickest sheet. Two times the thickness of the thickest sheet.

Most aircraft rivets have what kind of marking on their head?. A dimple. A raised dot. A raised cross. Two raised dash mark.

Whose law states; "A change in volume of a confined gas when held at a constant temperature would create an opposite change in the pressure of the gas.". Boyle's law. Charles' law. Bernoulli's law. Pascal's law.

Whose law states; "If the volume of a confined gas is held constant, the pressure will vary in the same way as the absolute temperature of the gas". Newton's law. Charles' law. Boyle's law. Pascal's law.

Who's law states; "An increase in pressure at any point in a confined liquid will produce an equal increase in the pressure at every other point in the liquid. Therefore, the pressure will always act at right angles to the container that encloses the liquid". Pascal's law. Bemoulli's law. Charles' law. Boyle's law.

Why are solution heat treated rivets refrigerated?. To keep the rivet at its proper dimensions for installation. To prevent intergranular corrosion to form. To increase the age hardening process. To remain soft and malleable.

What does a schematic diagram show?. The general arrangement of parts and/or their position, and the information to install the items. The internal construction or shape of the part. All of the parts are shown in their relative positions, but are expanded outward. Principles of operation rather than parts as they actually appear.
