Question 1

What tension test is designated for ASTM standard procedures for steel products?

Accepted Answer

A370

Answer

ASTM A370 is the designated standard procedure for the mechanical testing of steel products, including tension tests. This standard outlines the specific methods, definitions, and requirements for conducting various mechanical tests on steel, ensuring consistency and comparability of results across the industry. It is crucial for quality control and material specification in engineering applications involving steel.

Question 2

A big molecule made up of two alternating mers is called

Accepted Answer

Copolymers

Answer

A copolymer is a large molecule, or polymer, that is made up of two or more different types of monomer units, often referred to as 'mers,' arranged in an alternating or random sequence. This contrasts with homopolymers, which are composed of only one type of monomer. The combination of different mers allows for a wide range of material properties to be achieved.

Question 3

What's the name for a polymer with characteristics similar to rubber?

Accepted Answer

Elastomer

Answer

An elastomer is a polymer that possesses elastic properties, meaning it can undergo significant deformation under stress and then return to its original shape once the stress is removed. This characteristic is similar to that of natural rubber, making elastomers widely used in applications requiring flexibility and resilience, such as tires, seals, and shock absorbers.

Question 4

Which kind of steel uses carbon as its main strengthening agent?

Accepted Answer

Carbon Steel

Answer

Carbon steel is a type of steel where carbon is the primary alloying element used to enhance its strength and hardness. The mechanical properties of carbon steel, such as tensile strength and ductility, are largely determined by its carbon content. As the carbon percentage increases, the steel generally becomes harder and stronger but less ductile.

Question 5

Which kind of steel is 100% pearlite and contains 0.8% carbon?

Accepted Answer

Eutectoid

Answer

Eutectoid steel is a specific type of carbon steel that contains approximately 0.76% (often rounded to 0.8%) carbon. Upon slow cooling from its austenitic phase, this steel transforms entirely into pearlite, which is a lamellar microstructure consisting of alternating layers of ferrite and cementite. This unique composition and transformation give eutectoid steel distinct mechanical properties.
