None of these options

Which of the following is correct about the Driver's Harness Attachement?

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

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

Where lap belts and anti-submarine belts use the same attachement point, the tab or bracket to which they are attached, must have a minimum cross sectional area of 90mm^2 of steel to be sheared if failed in tension at any point of the tab

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

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

Systems are not part of the Detailed Bill of Material

Sub-assemblies are only part of the Detailed Bill of Material

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

Overhead costs must be taken into account in the Costed Bill of Material

0.69 m

0.87 m

1.17m

1.32 m

A team is competing in the Acceleration event at FSN. The car has a mass of 183kg. What is the work needed in order for the car to finish in 3.8 seconds with a speed of 133 km/h?

124.8 kW

32.8 kW

12.4 kW

38.3 kW

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

Yes, as long as the bolts exceed metric grade 8.8

Yes, as long as a minimum of two full threads project from the lock nut

Yes, unless the bolts are used in the brake system

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

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

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

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

From the driver's shoulders rearwards to the mounting point or structural guide, the shoulder harness is 8 degrees above the horizontal

A team is competing in the Skidpad Event at FSN. If the coefficient of friction is Uf=0.87 , what is the maximum velocity in order for the car to stay in track without losing contact with the ground? Assume that the car is racing in the centerline of the track width and g = 9,81 m/s^2

31.75 km/h

8.82 km/h

37.15 km/h

43.26 km/h
