Which of the following objectives of the business logic case is incorrect?
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.

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?
Correct Answer
B. 1. It can be the solution to d. only

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
Correct Answer
A. (m/M)g
Explanation
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.

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?
Correct Answer
A. This is allowed but only in the pits
Explanation
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.

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?
Correct Answer
C. Both A and B
6.
Which of the following are true?
Correct Answer
A. If a team uses electronically actuated Drag reduction system, then it is a part of LVS
Explanation
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.

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?
Correct Answer
A. 0
Explanation
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.

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?
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.

A second-order all-pass filter can vary the output phase from
Correct Answer
A. 0 degrees to -360 degrees
Explanation
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.

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?
Correct Answer
A. A
Explanation
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.
