Ensure that participants gain experience in producing business case and also balance potentially conflicting attributes.
- B.
Ensure that teams develop their own concept for the market strategies before vehicle launch

- D.
They must come up with separate approach for all the 3 static events to ensure the difference between all the static events.
Correct Answer
D. They must come up with separate approach for all the 3 static events to ensure the difference between all the static events.Explanation
The objective of coming up with a separate approach for all the 3 static events to ensure the difference between them is incorrect because it does not align with the purpose of a business logic case. A business logic case is meant to ensure that participants gain experience in producing a business case, develop market strategies, and understand concepts such as costing, profit, market attention, and sales volume for a new product launch. The objective of differentiating between static events does not contribute to these goals and is therefore incorrect.Rate this question:

Since composite can only be mechanically fastened and then bonded, how do we reduce the defects like delamination, resin corrosion, and fiber breakout? a. Aluminum is the best possible material option for fasteners b. Fasteners with large head for better stress distribution c. Contraction and expansion of fasteners can cause changes in clamping load d. Interference fit can be hazardous to the laminate e. Water absorption at exposed laminates can weaken it 1. Special sleeved fasteners can limit the chances of interference fit to some extent 2. Tailoring the lamina CTE in Quasi Isotropic laminates permits theoretical ‘zero CTE’ 3. Carbon-fiber composites may corrode galvanically if aluminum fasteners are used WHich of the following is incorrect?

A plate of mass M is placed on a horizontal frictionless surface and a body of mass m is placed on this plate, the coefficient of dynamic friction between this body and the plate is 'u'. if a force 2umg is been applied on the body of mass m along the horizontal direction the acceleration of the plate will be
- A.
(m/M)g
- B.
(m/(M+m))g
- C.
(2um/M)G
- D.
(2um/(m+M)))g
Correct Answer
A. (m/M)gExplanation
When a force is applied to the body of mass m, it will experience a friction force equal to umg in the opposite direction. According to Newton's third law, the plate will experience an equal and opposite force due to the friction between the body and the plate. This force will cause an acceleration on the plate. Since the mass of the plate is M, the acceleration of the plate can be calculated using Newton's second law, F = ma. Therefore, the acceleration of the plate will be (m/M)g.Rate this question:

A team installed an aerodynamic device on the car. During TI the wing of the car did not clear the height rule and so some adjustments were made to the wing mounts made of carbon fibre by cutting it as a result the pit was left dirty. Which of the following are false?
- A.
This is allowed but only in the pits
- B.
Is not allowed and team will incur penalties even if in pits
- C.
This is allowed only in a certain area under marshals
- D.
None of the above
Correct Answer
A. This is allowed but only in the pitsExplanation
Cutting the wing mounts made of carbon fiber to make adjustments is allowed, but only in the pits. This means that the team can make modifications to the aerodynamic device in the designated pit area without incurring any penalties. However, it is not allowed to make these adjustments outside of the pits or in any other area.Rate this question:

A team designs their steering system using steering stop made of nylon patches. The steering wheel when turns an angle of 32 degrees, the front right turns by an angle greater than 39 degrees and the rear left wheel turns an angle of 5.85 degrees which is actuated by electrical motors which are mounted to the rear of the rear bulkhead when seen from side view. How many rules are violated?
- A.
Equal to the minimum, modulus of difference of the outer diameter and inner diameter of a bar for mounting the shoulder harness divided by 2
- B.
Equal to the area of the sample test piece made for the 3-point bend test (ft2) divided by 0.74 (approx)
- C.
Both A and B
- D.
Neither A or B

Which of the following are true?
- A.
If a team uses electronically actuated Drag reduction system, then it is a part of LVS
- B.
Team GFR uses a restrictor of diameter 19mm and in order match their car's colour way, they decide to use orange colour wiring for the wiring in their ETC. They are allowed to do so.
- C.
The steering is allowed to have a hexagonal shape and a shutdown button with a 40mm diameter can be mounted behind the steering wheel.
- D.
All of the above
Correct Answer
A. If a team uses electronically actuated Drag reduction system, then it is a part of LVSExplanation
The given answer states that if a team uses an electronically actuated Drag reduction system, then it is a part of LVS. This means that if a team chooses to use this specific type of system, it is considered to be a part of the LVS (Low Voltage System). This implies that the LVS includes the electronically actuated Drag reduction system as one of its components.Rate this question:

A car is designed in such a way that the exhaust system and the filler neck are present on the same side of the car. the filler neck is present behind the main hoop. the exhaust system is been covered so that no person doesn't come in direct contact with it. how many rules are been broken?
- A.
0
- B.
1
- C.
2
- D.
Data no sufficient
Correct Answer
A. 0Explanation
The question states that the exhaust system and the filler neck are present on the same side of the car, and that the filler neck is located behind the main hoop. It also mentions that the exhaust system is covered to prevent direct contact with it. Based on this information, there are no rules being broken. The design of the car seems to be intentional and meets the requirements of keeping the exhaust system covered and preventing direct contact with it. Therefore, the correct answer is 0.Rate this question:

A team has designed their electrical system as such that, current from the battery goes to PMS-from, PMS it goes to starter relay which on starting of the car provides 12V to the dashboard, from which power is circulated to the rest of the car. Which of the following is true?
- A.
Indicators on the main power pcb are not allowed so TI won’t get cleared.
- B.
TI will get not get cleared.
- C.
TI will get cleared.
- D.
None of the above
Correct Answer
B. TI will get not get cleared.Explanation
The team has designed their electrical system in a way that the current from the battery goes to the PMS-from, then to the starter relay, which provides 12V to the dashboard upon starting the car. From the dashboard, power is distributed to the rest of the car. The indicators on the main power pcb are not allowed, so TI (presumably referring to Technical Inspection) will not get cleared.Rate this question:

A second-order all-pass filter can vary the output phase from
- A.
0 degrees to -360 degrees
- B.
-90 degrees to -360 degrees
- C.
180 degrees to 360 degrees
- D.
None of these
Correct Answer
A. 0 degrees to -360 degreesExplanation
A second-order all-pass filter is a type of electronic filter that allows all frequencies to pass through while changing the phase of the output signal. It can vary the output phase from 0 degrees to -360 degrees, which means it can shift the phase of the output signal by any value between 0 degrees and -360 degrees. This range of phase shift allows for a wide range of applications and flexibility in signal processing.Rate this question:

Technician A says turbulence causes the air-fuel mixture to burn more rapidly. Technician B says turbulence slows the spread of the flame so the mixture has more time to burn. Who is right?
- A.
A
- B.
B
- C.
Both A and B
- D.
Neither A nor B
Correct Answer
A. AExplanation
Technician A is correct. Turbulence in the air-fuel mixture causes it to burn more rapidly. This is because turbulence increases the mixing of fuel and air, resulting in a more even distribution and faster combustion. This increased turbulence can be achieved through various means, such as using turbulence-inducing devices in the combustion chamber or designing the intake and exhaust systems to promote turbulence. Technician B's statement is incorrect as turbulence actually accelerates the burning process rather than slowing it down.Rate this question:
