ENGINEERING BTEC LEVEL 2 UNIT 1 EXAM FULLY SOLVED #5
2025-26
Aerospace engineering - correct answer Construction, testing, design and development
of aeronautical and astronautical engineering.
Automotive engineering - correct answer Design, manufacture and operations of
motorcycles, automobiles, buses and trucks and their respective engineering
subsystems.
Communications engineering - correct answer Brings together electrical engineering
with computer science to enhance telecommunications systems. Overlaps with
broadcast engineering.
Electrical engineering - correct answer A field of engineering that generally deals with
the study and application of electricity, electronics, and electromagnetism.
Mechanical engineering - correct answer A discipline of engineering that applies the
principles of Physics and materials for analysis, design, manufacturing and
maintenance of mechanical systems.
Biomedical engineering - correct answer The application of engineering principles and
design concepts to medicine and biology for health care purposes. This field seeks to
close the gap between engineering and medicine.
Chemical engineering - correct answer Branch of engineering that applies physical
sciences and chemistry and physics and life sciences (biology) together with maths to
convert raw materials or chemicals into more useful or valuable forms.
MIG Welding - correct answer Uses electricity to generate heat required to weld
materials.
Suitable for large scale production. Varying thickness of materials can be joined.
Reduced cost due to the production of neat and clean metal deposits on the workpiece
means there is no need for extra cleaning.
Name some PPE - correct answer Some pretty cute options here
Advantages and Disadvantages of Drilling Machines - correct answer Advantage:
Accurate precision drilling
Drill a variety of diameters
Disadvantage: Must be operated by a skilled worker
Not portable (??????????????????)
Advantages and Disadvantages of a miling Machine - correct answer Advantage: The
table of the machine can be moved to an accuracy of 0.02mm
, Special attachments can be mounted on the machine to perform operations that are
performed in other machine tools
Disadvantage: Too many fking parts to label
The cost of the milling machine is high
Uses a lot of electricity
What the hell does a Turning Machine do?? - correct answer Turning is a form of
machining, a material removal process, which is used to create rotational parts by
cutting away unwanted material.
Describe the process of Sand Casting plz m8 - correct answer
Two freaking H&S issues with sand casting - correct answer Be cautious and pay
attention to your surroundings.
Wear PPE
2 advantages and disadvantages of sand casting :D - correct answer Advantage: Low
cost
Can produce large castings
Disadvantage: Bad surface finish (due to sand indentation)
Many defects arise in the casting (no good control on the process, die casting is much
better)
What is MIG Welding? - correct answer Metal inert gas (MIG) welding is a welding
process in which an electric arc forms between a consumable wire electrode and the
workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.
2 advantages and disadvantages of MIG welding please - correct answer Advantage:
Creates a clean join
Suitable for large scale production
Disadvantage: High initial set up cost
Requires a skilled welder
What is TIG Welding? NOT MIG WELDING, TIG!!!!!! - correct answer Tungsten inert
gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten
electrode to produce the weld.
2 advantages and disadvantages of TIG welding ;) - correct answer Advantage: High
quality and strong welding achieved by TIG
Non-corrosive and ductile joints
Disadvantages: They are slower than any other welding process. Lower filler deposition
rate.
High initial cost.
What is oxyacetylene welding (gas welding) ?? - correct answer A process that uses
fuel gases and oxygen to weld and cut metals.
