A)A
B)B
C)SAME
3.Which of the following is true:
A) People in the dynamic area may wear closed-toe shoes
B) Alluminium wheel nuts may be hard anodized and in pristine condition, in order to be used.
C) The IA must be at least 3.94in high and 0.66ft wide for a minimum distance of 0.22yds forward of the front bulkhead.
D) Scatter shields must be constructed of perforated 2mm steel or 3mm alluminium alloy 6061-T6.
4. Which of the following could be the distribution of temperature in boundary layer?
A

D
5. If the volume of the plenum is 5% larger than the volume of the air intake runner system, can it be placed anywhere upstream the throttle body:

6.A machine needs a damping machine to minimize the vibrations transferred to the ground of the workshop. Initially they wanted to design the system with frequency ratio equal to three. They estimated that the induction frequency to be equal to 25 Hz, however after the first tests they found out the frequency ratio was 1.2. The only choice they had was to select the damping coefficient to be equal to 0.4*natural frequency. Determine the value of C of the system. Consider the machine as a single degree of freedom with mass m=20kg. (Round up in two decimals, g=9.81m/s^2, use “.” as decimal separator)
7.If an object has a weight of 10 lbf on the moon, what would the same object weigh on Jupiter?
A) 139lbf
B) 137lbf
C) 61 kg
D) 62 kg
8. An inventor claims to have invented a device which absorbs 2500 Btu of heat and produces 2000 Btu of work. If the heat sink for the device is ice water (32 F), what would be the minimum source temperature?
A) 2005 (F)
B) 2020 (F)
C) 1093.33 (C)
D) 1090.24 (K)
9. Below you can see a front wing. What would be the rotation of the endplate vortex?
A. Clockwise
B. Counter-clockwise
10. Find current I in the circuit. Give your answer on A and to 3rd decimal (DONT ROUND your answer)
12. For a neutral suspension design, what would be the effect of the aerodynamic package?
A. Oversteer
B. Understeer

C) After leaving the track the vehicle should be powered down.
D) If a puncture occurs on the endurance event due to severe loss of air in the tyre the vehicle will be scored DNF.
15. Which of the following magnitudes is plotted? Consider only the rear wing and the endplates.
A. Static pressure (Red max, Blue min)
B. Dynamic pressure (Blue max, Red min)
C. Z velocity (Blue max, Red min)
D. Total pressure (Red max, Blue min)
16.Which of the following is not true:
A) All aerodynamic devices rearward of a vertical plane through the rearmost portion of the front face of the driver head restraint support, excluding any padding, set to its most rearward position must be lower than 1,2m from the ground, without the driver.
B) Positive locking mechanisms can include nylon lock nuts of ISO10512 and locking plates.
C) The background shape of the vehicle number can be square or rectangular.
D) The application of absorbent materials on the outside of the exhaust manifold is not permitted.
