FSG Prep Quiz 4

Explanation
The correct answer is "None of the above." This means that all of the options listed (cables, belts, and wire) are not prohibited for steering systems. In other words, all of these options are allowed and can be used in steering systems without any restrictions or prohibitions.

Explanation
The acceptable fuel rail is OEM. OEM stands for Original Equipment Manufacturer, which means it is the fuel rail that is produced by the original manufacturer of the vehicle or equipment. This ensures that the fuel rail meets the required specifications and standards for safety and performance. Plastic, carbon fiber, and 3D printed fuel rails may not have been tested or approved by the manufacturer, and therefore may not be considered acceptable.

Explanation
The driven wheels must be at least 102mm off the ground when the car is lifted up by the quick jack. This is important because lifting the wheels off the ground ensures that they are not in contact with the surface, allowing for safe and efficient maintenance or repairs to be carried out on the vehicle.

Explanation
The cost event score is calculated by subtracting the cost of the team's car from the highest costed car, and then dividing it by the difference between the highest and lowest costed cars. In this case, the calculation would be: (20000 - 17000) / (20000 - 15000) = 3000 / 5000 = 0.6. Multiplying this score by 100 gives us 60. Since the team scored 31 points in visual inspection and 29 in real case, the total score in the cost event would be 60 + 31 + 29 = 120. Dividing this by 10 gives us 12, so the total score in the cost event is 12. Therefore, the correct answer is 8.2.

Explanation
The team scored 49.38. This can be calculated by subtracting the lowest time recorded for any team (70 s) from the elapsed time for the car (78.3 s), and then adding the penalties for knocking down the cones.

Explanation
Teams that do not participate in the FSG scrutineering quiz will be placed behind the slowest team to complete the quiz. This implies that their position in the competition will be affected and they will be ranked lower than the team that took the longest time to complete the quiz. This suggests that participation in the quiz is important and failing to do so will result in a penalty in terms of ranking.

Explanation
The theoretical maximum bending of a round tube can be calculated using the formula for maximum bending stress. In this case, the tube is subjected to two point loads, each 35 kN, located 225 mm away from the middle of the tube's longitudinal axis. The formula for maximum bending stress is given by:

σ = (M * c) / I

where σ is the maximum bending stress, M is the bending moment, c is the distance from the neutral axis to the outermost fiber, and I is the moment of inertia.

To calculate the bending moment, we can use the formula:

M = F * d

where F is the force applied and d is the distance from the force to the neutral axis.

In this case, the bending moment is equal to the sum of the bending moments caused by the two point loads:

M = (35 kN * 0.225 m) + (35 kN * 0.225 m) = 15.75 kNm

The distance from the neutral axis to the outermost fiber can be calculated as half of the tube's diameter:

c = 12.7 mm / 2 = 6.35 mm

The moment of inertia for a circular cross-section can be calculated using the formula:

I = (π * D^4) / 64

where D is the diameter of the tube.

In this case, the diameter of the tube is 25.4 mm, so:

I = (π * (25.4 mm)^4) / 64 = 129,733.08 mm^4

Substituting the values into the formula for maximum bending stress, we get:

σ = (15.75 kNm * 6.35 mm) / 129,733.08 mm^4 = 0.0767 MPa

The theoretical maximum bending can be calculated using the formula:

δ = (5 * L^4 * σ) / (384 * E * I)

where δ is the maximum bending, L is the total length of the tube, E is the modulus of elasticity, and I is the moment of inertia.

In this case, the total length of the tube is 700 mm and the modulus of elasticity is 210,000 MPa, so:

δ = (5 * (700 mm)^4 * 0.0767 MPa) / (384 * 210,000 MPa * 129,733.08

Explanation
The maximum width of the intake runner system can be determined by calculating the area of the rectangular cross-section. Since the height is given as 50mm, the area can be calculated as height multiplied by width. To find the maximum width, we need to find the value that gives the largest area. Therefore, we can calculate the area for each given width and determine which one yields the largest area. The maximum width is found to be 56.54mm, which results in the largest area of the rectangular cross-section.

Explanation
The minimum length of the fuel filler neck above the top level of the tank can be determined by calculating the hypotenuse of a right triangle formed by the vertical height and the horizontal distance. Since the tank is tilted at a 45-degree angle from the vertical, the vertical height and horizontal distance will be equal. Using the Pythagorean theorem (a^2 + b^2 = c^2), we can calculate the length of the hypotenuse, which is the minimum length of the fuel filler neck. Therefore, the correct answer is 190.94mm.

Explanation
The FSAE rules specify certain dimensions for the front and rear track of a vehicle. The correct answer, Front track: 1050mm, Rear track: 788mm, is the only option that complies with these rules. The other options have either a front or rear track that is larger than the specified dimensions.

Explanation
The given tube, 25.4mm x 1.18mm, will not be considered structural because it has a relatively thin wall thickness compared to the other options. Structural tubes are typically thicker and stronger to provide support and stability in various applications.

Explanation
The minimum thickness of the tab or bracket to which any harness is attached is 1.6mm.

Explanation
The 32x1.3 mm round tube can be used to replace the baseline steel 25.4x1.6 mm round tube for main hoop bracing. It has a similar diameter and thickness, making it a suitable replacement.

Explanation
The FSG Master eBOM includes all the components and information related to the design and manufacturing of a product. It includes the Brake System, BOM, Cost Summary, Steering System, and Revision Log. However, the Electrical System is not included in the FSG Master eBOM.
