Question 1

Carbon content in wrought iron is
A)0.15%
B)0.25 to 1.5%
C)2 to 4%
D)more than 4%

Accepted Answer

Wrought iron is known for its very low carbon content, which is typically around 0.1% to 0.25%, making option A correct.

Question 2

The ratio of tensile strength to compressive strength of steel is
A)less than 1
B)equal to 1
C)more than 1
D)nothing can be said definitely

Accepted Answer

The tensile strength and compressive strength of steel are generally considered to be equal, hence the ratio is 1. This is because steel exhibits similar behavior under tension and compression, making it a highly versatile material in construction and engineering applications.

Question 3

Ribs are made on steel wires to increase
A)strength is compression
B)strength is tension
C)bond strength
D)fatigue quality

Accepted Answer

Ribs are made on steel wires to increase bond strength between the steel and concrete in reinforced concrete structures, enhancing the overall structural integrity.

Question 4

The property of metal enabling it to be drawn into thin weir is known as
A)malleability
B)ductility
C)toughness
D)plasticity

Accepted Answer

Ductility is the property of a material that allows it to be drawn out into a thin wire. Malleability allows materials to be formed into thin sheets, toughness is the ability to absorb energy and plastically deform without fracturing, and plasticity is the deformation of a material undergoing non-reversible changes of shape in response to applied forces.

Question 5

Non-ferrous Materials
A)Market form of copper is/are
B)ingots
C)sheets
D)tubes

Accepted Answer

The answer of Non-ferrous Materials
A)Market form of copper is/are
B)ingots
C)sheets
D)tubes...

Question 6

The ore from which aluminium is extracted economically is
A)kaolin
B)kryolite
C)corundum
D)bauxite

Accepted Answer

Bauxite is the primary ore from which aluminium is extracted economically due to its high content of aluminum hydroxide.
