◉ In most brittle materials such as cast iron, the compressive
strength is several times greater than the tensile strength.
(True/False) Answer: True
◉ The ability of a material to deform or stretch without fracture is
known as: (Multiple choice)
Question 43 options:
A) Ductility.
B) Yield strength.
C) Malleability.
D) Elasticity. Answer: A) Ductility.
◉ What is the lightest commercial metal with a density of 1800
kg/m³ (0.065 lb/in³)? (Multiple choice)
Question 44 options:
A) Copper
B) Aluminum
,C) Vanadium
D) Magnesium Answer: D) Magnesium
◉ Cast steel is a ferrous alloy with a maximum carbon content of
approximately: (Multiple choice)
Question 45 options:
A) 0.75%
B) 0.35%
C) 0.60%
D) 0.82% Answer: B) 0.35%
Cast steel is a ferrous alloy with a maximum carbon content of
approximately 0.35%. This carbon content helps determine the
properties and characteristics of the cast steel, such as its strength,
hardness, and machinability.
◉ What is the most common method of steel formation? (Multiple
choice)
Question 46 options:
A) Ingot casting.
B) Ingot rolling
C) Continuous casting
D) Continuous ingot rolling Answer: C) Continuous casting
,Continuous casting is the most common method of steel formation
in modern steelmaking processes. This method involves
continuously casting molten steel into semi-finished products, such
as billets, blooms, or slabs, which are then further processed
through rolling or other techniques to produce final products. It is a
widely used and efficient method for producing a variety of steel
products in a continuous and cost-effective manner.
◉ Lamellar tearing in a welded connection can be mitigated by:
(Multiple choice)
Question 47 options:
A) reducing the temperatures used in welding.
B) reducing the volume of weld metal from complete to partial
penetration.
C) changing the weld process used.
D) changing the base materials used. Answer: B) reducing the
volume of weld metal from complete to partial penetration.
Lamellar tearing in a welded connection can be mitigated by
reducing the volume of weld metal from complete to partial
penetration. This helps reduce the risk of lamellar tearing by
minimizing the stresses that can lead to this type of defect in the
welded joint.
, ◉ When a pressure vessel is made from formed plates, they are
usually arranged: (Multiple choice)
Question 48 options:
A) with the rolling direction around the circumference.
B) with the rolling direction in a pattern alternating between around
the circumference and along the length of the pipe.
C) with the rolling direction along the length of the pipe. Answer: C)
with the rolling direction along the length of the pipe.
◉ The ductility measured through the thickness of the plate is
usually the lowest of all. The welding of large heavily restrained T-
joints may therefore result in: (Multiple choice)
Question 49 options:
A) Ductile tearing.
B) Lamellar tearing.
C) Hydrogen tearing.
D) Brittle tearing. Answer: A) Ductile tearing.
The welding of large heavily restrained T-joints may result in ductile
tearing, particularly when the ductility through the thickness of the
plate is the lowest. Ductile tearing involves significant plastic
deformation before fracture occurs, which can occur in situations
where the material is heavily restrained and subjected to welding-
induced stresses.
