Quiz „Electrical“
1. You have an electric car with these specifications:
How far can you drive with one load? Give answer to nearest whol number in km.
2. For this Wheatstone Bridge based NTC temperature measurement circuit, which is the lowest voltage measurement (VAB) that is possible to obtain at 60ºC? (NTC B: 3435 +/-1%) Give answer in Volts rounded to two decimal points.
3. Which of the following statements about the Tractive System Accumulator are wrong? (Multiple choice)
See FSG rules 2023. Correct answers:
4. Which statements about the travel of the driving pedal is correct
FSG Rules 2023: T11.8.1, T11.8.5
5. Which of the following statements is false regarding the difference between Lead-based batteries, Nickel-based batteries and Lithium-based batteries?
no solution currently
6. A capacitor with a capacitance of 100 μF is currently charged to a voltage of 199.8V. How much additional energy is needed to charge it to a voltage of 301.4V. Give answer to 4 significant figures in Joules
W = 0.5 * C * U^2
∆W = W_end – W_start = 0.5 * C ((U_end)^2 – (U_start)^2)
7. How long will it take to discharge C1 below 60V using the following constant current sink if it is initially charged at 565V? (MOSFET’s VGSth: 4V) Give answer to two decimal places in secs.
Circuit’s current: MOSFET will operate in linear zone, close to the activation voltage. Therefore, as VGSth is 4V, VS can be taken as 8V. From these 8V and the 47R current limiting resistor, the discharge current of the circuit will be 8/47->0,17A As the constant current discharge of a capacitor depends on capacity, as V=i·t/C-> t=V·C/i=(565-60)·0,0012/0,17=3,56s
8. Your BSPD has been triggered although the driver did not touch the driving pedal. What could have gone wrong? (multiple choice)
9. The previous season you could recuperate only 27% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 69% of the initially stored energy. Knowing that you had 6.3 kWh of energy in your accumulator during the last season, how much energy must your new accumulator have, if you assume, that it’s the same length and speed? Give answer in kWh
E_new = E_old * (1+0.27)/(1+0.69)

Quiz „General Engineering“
1. Calculate the maximum possible cornering speed (in kph) for the following FSAE car when going through a 20 m radius corner.
m = 260kg; cl *A * Rho = -6 kg/m; Tyre coefficient of friction = 1.5; g = 9.81 m/s^2.
The vehicle can be treated as a point mass, driving resistances neglected. Round to 1 decimal
2. You would like to drink a cup of very hot coffee with milk early in the morning, but you are in a hurry and have only 5 minutes until you have to leave for work. At which time after brewing should you add the cold milk to the coffee and stir in order to decrease the temperature of the mixture as much as possible: a) 0 minutes (immediately), b) 2 minutes, or c) 4 minutes? Suppose that the stirring can be done instantaneously and that you need the last one minute for drinking.
brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature 0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).
Please enter only the letter of the corresponding answer
The driving „force“ for the cooling of the coffee is the temperature difference between the warm coffee and the environment (room temperature), which leads to an exponential drop in coffee temperature. The temperature difference is greatest immediately after brewing. The later we stir in the milk, the lower the coffee temperature has already dropped. On the other hand, lowering the temperature by the milk becomes smaller the longer we wait. So we let the coffee cool down on its own for as long as possible in order to bring about the temperature reduction by the cold milk at the end. The greatest possible cooling is therefore achieved when the milk is added after 4 minutes.
3. Calculate the force Fc working at point C. Give answer in kN rounded to one decimal place.
Forces at point A: Rax = 3kN, Ray = 9kN, Ma = 10kN/m
Moment Equation around point D:
0 = -Fc x 1m – (60kN x 3m) x 4m + Ray x 5.5m – 10kN/m
Fc = -190 510 N
Fc = -190.5 kN
4. A 30 lbs model helicopter flying at 51 mph, calculate its kinetic energy. Answer in J to 3 significant figures.
KE=0,5 * m * v^2
5.
How high (in m) can a column of liquid be lifted by a reciprocating piston, neglecting leakage and losses, if the air pressure is 101300 Pa and the pressure p₁ approaches zero?
Example Input 14.3 (use a point, no unit)
6. The given gearbox consists of two gear sets with wheels 1, 2 and 3, 4 respectively. The wheels are fixed to their shafts. Calculate the drive speed (in rpm) of wheel 4?
Given: n1=600 rpm, z1=18, z2=90, z3=24, z4=120

8. An object is fired vertically upwards from the ground at time t = 0 s in still air at a speed of 9.6 m/s. On the way up, what is the height of the object above the ground when it has a speed of 1.9 m/s. At what time does it reach this height on the way down? Give both answers separated by a comma to one decimal place.
Possible solution:
9. A ball at a height of 20ft on Earth with a gravitational field strength of 9.81 N/kg, gained 284 J of gravitational potential energy. Calculate the mass of the ball. Give answer to two decimal place in kg.
E = m * g * h
10. A spring in a church clock has a spring constant of 10 N/m. What is its elastic potential energy store if it is stretched 8 m? Give answer in Joules to three significant figures.
