Here's what to expect:
- 10 thought-provoking questions
- Multiple choice and open-ended formats
- Engagement for both students and professionals
1) Find the value of resistor Rx in Ohms if the voltage difference at V+ and V- is 1.29V. Round to one decimal place.
2) There are 3 teams A,B and C. Team A run in acceleration at 4.02 , team B at 4.07 and team C at 4.05. In skidpad team A run at 5.01, team B at 5.07 +1 DOO and team C at 5 seconds. Team's A vehicle is at unfisnished state, team B delayed CRD, DSS and MU for 55080 seconds. Finally team C submited all documents at 9/5/2022 and received correction for VSV at 13/5/2022 and send it back correctly at 17/5/2022. If your points penalty are 44.61, which team are you?
A
B
C
3) An M14x2 hex bolt with nut is used to clamp together two 15mm steel plates of E=207GPa each. Determine the bolt stiffness ( write in kN/mm keeping one decimal).Note: Ιn total bolt's lenght round up in nearest 5mm
4) An automobile engine has a maximum power output of 75 hp, which occurs at an engine speed of 2200 rpm. A 10% power loss occurs through the transmission and differential. The rear wheels have a radius of 15 in. And the automobile is to have a maximum speed of 75 mph along a level road. At this speed, the power absorbed by the tires because of their continuous deformation is 27 hp. Find the maximum permissible drag coefficient for the automobile at this speed. The car’s frontalarea is 24 ft2. Answer with two decimals
5) A logic plan with the three logic valued inputs DG1, DG2, DG3 is shown in the picture. How many possible input combinations result in a logic true at the output?
6) The selected baud rate on a UART receiver is 115200 bits/sec. If the system’s crystal oscillates at a frequency of 50 MHz, the timing error of the UART sample signal is approximately (assuming clocks are in phase):
A. 1.256 ns
B. 0.556 ns
C. 5.241 ns
D. 0.011 ns
7) An airplane alloy is described by the conditional equation : σ = 100000 ε^0.55 (psi). Calculate the material's true and engineering UTS.
A. UTStrue = 8450psi UTSeng = 292bar
B. UTStrue =150*10^6 inH2O UTSeng = 41880psi
C. UTStrue = 4963bar UTSeng = 1.150*10^6 inH2O
D. UTStrue = 71982psi UTSeng = 45000psi
8) An engine generator rated 9000 kVA at 80 power factor, 3 phase, 4160 V has an effiency of 90%. If overall plant efficiency is 28%, what is the heat generated by the fuel?
A. 18,8000 KW
B. 7,500 KW
C. 28,8000 KW
D. 25,714 KW
9) Which statements are true according to the FS rules and the competition handbook?
A) The EI of the vertical side of the front bulkhead support structure must be equivalent to at least the EI of one baseline steel tube that it replaces.
B) At least two separate sensors must be used as APPSs. They may share supline lines but not signal lines
C) The circular restricting cross section may be movable
D) After technical inspection a team may replace their low voltage batteries
E) With a “reclined driving position”, in side view the lap belt must be between an angle of 60° and 80° to the horizontal.
F) A team which uploads a VSV with a previous year vehicle will get a 25 points penalty
G) Official announcements are considered part of the rules.
H) “Brake-by-wire” systems are prohibited.
I) All aerodynamic devices must not extend further rearward than 250mm from the rearmost part of the rear tires.
Ia) The NodeID has to be set to 0x011 at the competition
