𝑔=9.81 𝑚/sec2

A) 31.75km/h

B) 8.82km/h

C) 37.15km/h

D) 43.26km/h

2) A team is in the process of validating the compliance of the shoulder harness bar used in their car. Choose the part in which their configuration is incompliant:

A) The steel tube has a thickness of 2 mm, and a 0.26% in carbon and 1.7% manganese content.

B) The bar is bent (not straight) and the beam uses an analysis method of inducing 7kN to each attachment in the horizontal plain to prove compliance

C) The attachments are positioned 220 mm apart, measured center to center, and have a thickness of 1.7 mm

D) From the driver’s shoulders rearwards to the mounting point or structural guide, the shoulder harness is 8° above the horizontal

3) A team is evaluating if they can save weight by shortening some of their critical fasteners. Are you allowed to shorten bolts?

A) No

B) Yes, as long as the bolts exceed metric grade 8.8

C) Yes, as long as a minimum of two full threads project from tha lock nut

D) Yes, unless the bolts are used in the brake system

4) What is the minimum static ground clearance of a vehicle including a driver?

A) 25 mm

B) 30 mm

C) 40 mm

D) 50 mm

5) The weight distribution of a car is 44% to the front and 56% to the rear axle. The wheelbase of the car is 1570 𝑚𝑚. In what distance, measuring from the rear axle, is the CoG located?

A) 0.69 m

B) 0.87 m

C) 1.17 m

D) 1.32 m

6) What is true about the documentation for the Cost & Manufacturing event?

B) “Sub-assemblies” are only part of the Detailed Bill of Material

C) For every material in the Costed Bill of Material, a receipt is required

D) Overhead costs must be taken into account in the costed Bill of Material

7) Which of the following is correct about the Driver’s Harness Attachment?

A) A minimum cross-sectional area of 60 mm^2 of the same steel used in the car must be physically tested to prove structural rigidity.

B) A belt can be regionally exposed to the engine or any other significant heat source, as long as it is not passing through the firewall.

C) Where lap belts and anti-submarine belts use the same attachment point, the tab or bracket to which they are attached, must have a minimum cross sectional area of 90mm2 of steel to be sheared if failed in tension at any point of the tab

D) An attachment welded to a steel structure must be able to carry 13 kN for shoulder and lap belts, and 6.5 kN for anti-submarine belts

8) If a full cylinder has a Moment of Inertia of J = 1,08 kg/m^2, what is the Moment of Inertia of a full cylinder with the same mass but half the diameter?

A) 0.16 kg/m^2

B) 0.27 kg/m^2

C) 0.73 kg/m^2

D) 0.84 kg/m^2

9) Your team is at the design event during FSN2020 and it’s quite cold for this time of the year, 18 degrees C. To impress the judges, you decide to make some tea for them.

C) The fuel tank can be made of flexible material

D) The fuel tank must be made of a rigid material to prevent failure under loading.

11) Please read these two statements concerning the Fuel Filler Neck for CV Class at FSN2020.
