QUESTION 1

1. The material that has the lowest stress per unit of straindiagram is:

		Wood
		Cast Iron
		Concrete
		High strength steel

QUESTION 2

1. Aluminum Metals subjected to loads:

		Do not exhibit a clearly defined yield point compared tosteel.
		Have a greater difference between tensile and yield strengthscompared to steel.
		Have a Modulus of elasticity one-third greater than structuralsteel.
		Have a coefficient of Thermal expansion one-half that ofstructural steel.

QUESTION 3

1. An alloying element is any element added during the manufactureof steel that is not one of four (4) non-metals. An example of analloying element is:

		Copper
		Carbon
		Silicon
		Sulfur

QUESTION 4

1. The addition of some metallic elements to steels affect theproperties of the metal. The ability to alter the steel corrosionresistance can be effected by the elements:

		Chromium, Copper, Molybdenum
		Aluminum, Vanadium
		Cobalt, Nickel
		Lead, Tellurium

QUESTION 5

1. An alloying element is any element added during the manufactureof steel that is not one of four (4) non-metals. An example of analloying element is:

		Lead
		Carbon
		Silicon
		Sulfur

QUESTION 6

1. An alloying element is any element added during the manufactureof steel that is not one of four (4) non-metals. An example of analloying element is:

		Aluminum
		Carbon
		Silicon
		Sulfur

QUESTION 7

1. The mechanical properties of the metal is determined by:

		Grain size
		Material color
		Initial crystalline structure
		Material uniformity

QUESTION 8

1. Most low carbon and structural steels are usually referred toby their appropriate designation:

		ASTM code
		Shape code
		Tensile Stress
		SAE/AISI code

QUESTION 9

1. The addition of some non-metallic elements to metals affect theproperties of the metal. The addition of silicon:

		Increases hardness
		Promotes uniformity of grain structure
		Retains malleability
		Improves corrosion resistance
