For steel material minimum carbon percentage should be
- A.
0.1%
- B.
0.5%
- C.
0.2%
- D.
0.6%
Correct Answer
A. 0.1%Explanation
Steel is an alloy primarily composed of iron and carbon. The minimum carbon percentage required for steel material is 0.1%. This is because carbon plays a crucial role in the strength and hardness of steel. It helps to enhance the steel's ability to be heat-treated and provides it with the desired mechanical properties. A carbon percentage below 0.1% would result in a material that is not considered steel. Therefore, 0.1% is the minimum requirement for carbon content in steel.Rate this question:

All forward facing edges on the bodywork should have forward facing radii of at least:
- A.
38 mm
- B.
35 mm
- C.
30 mm
- D.
40 mm
Correct Answer
A. 38 mmExplanation
All forward-facing edges on the bodywork should have forward-facing radii of at least 38 mm. This means that the edges should have a smooth curve with a minimum radius of 38 mm when viewed from the front. This is important for safety reasons as sharp edges can cause injury in case of a collision. Additionally, a larger radius helps in reducing aerodynamic drag and improving the overall performance of the vehicle.Rate this question:

The side impact structures should consist of minimum ….. number of members:
- A.
Three (3)
- B.
Four (4)
- C.
Two (2)
- D.
Five (5)
Correct Answer
A. Three (3)Explanation
The side impact structures should consist of a minimum of three members. This is because having three members provides better structural integrity and stability during a side impact collision. With three members, the impact forces can be distributed more evenly, reducing the risk of intrusion into the passenger compartment and minimizing the potential for injuries. Having fewer than three members would compromise the effectiveness of the side impact structures in protecting the occupants of the vehicle.Rate this question:

With use of gussets or triangulations more impact zone members are allowed:
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The use of gussets or triangulations allows for more impact zone members because they provide additional support and reinforcement to the structure. By adding these elements, the load is distributed more evenly across the members, reducing the stress on each individual member and allowing for a greater number of members to be included in the impact zone. This helps to increase the overall strength and stability of the structure, making it more resistant to impact or external forces.Rate this question:

2 mm
- B.
1 mm
- C.
5 mm
- D.
1.5 mm
Correct Answer
D. 1.5 mmExplanation
The correct answer is 1.5 mm because the thickness of a firewall must be sufficient to provide adequate protection against the spread of fire. A firewall is a barrier designed to prevent the spread of flames and smoke from one area to another in case of a fire. A thickness of 1.5 mm would provide a suitable level of fire resistance, ensuring that the firewall can effectively contain the fire and protect adjacent areas.Rate this question:
-
- 38.
Multiple panels can be used to form the firewall:
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Multiple panels can be used to form the firewall. This means that instead of using a single panel, multiple panels can be joined together to create a firewall. This allows for flexibility in terms of size and shape, as well as ease of installation and maintenance. It also provides better protection against fire hazards by creating a stronger barrier. Therefore, the statement "True" is the correct answer.Rate this question:
