Quiz „Electrical“

1 / 10

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

Calculate the gravitational potential energy of a 4 kg object at 15 m above Earth’s surface with gravitational field strength of 9.81 N/kg. Give answer to three significant figures in J.

2 / 10

The Wet Skid Pad World Record was set at FSN2019 by TU Delft. They managed to set a time of 4.901 for the left circle and a time of 5.031 for the right circle. Assume the run was completed perfectly along the center line of the circles. What was their average speed during this record run? Give answer to two decimal places in mph.

3 / 10

The kinetic energy of a 8 lbs 4 oz box as it was dropped reaching ground is 10125J. Determine the speed as it lands. Give answer to one decimal place in m/s.

4 / 10

in m, to decimal numbers seperated by a point (example: 150.00), no unit requirment for the solution

5 / 10

During last year acceleration a top speed of 100 km/h was reached. Due to big improvements in the new drivetrain, the new vehicle reaches a top speed of 120 km/h. The aerodynamics chief has some worries about the stability of the rear wing bracing due to the higher aerodynamics load. Given the geometry below, by how much % does the bearing force in point A change in comparison to last year? (The aerodynamic package did not change and therefore some values can be assumed for both vehicles). Give answer rounded to one decimal place.

CL=3.8     CD=1.2     A=1 m²     rho=1.1 kg/m³     L1=50 mm     L2= 100 mm     H1= 125 mm     H2= 165mm

An air stream dot{M}_L = 5.5  kg/s, cp_L=1 kJ/(kgK) is to be heated in a plate heat exchanger from θ_L′=20∘C ′ to θ_L′′=150∘C. For this purpose, a flue gas stream dot{M}_R = 7.22, cp_R=1.1 kJ/(kgK) with a temperature of θ_R′=300∘C is available. The overall heat transfer coefficient is k=15 W/(m^2*K).
What is the required heating surface AAA if the fluid streams are arranged in counterflow?
  • p2 = p1 * (V1/V2)^gamma
  • gamma= 1.4

7 / 10

An air as an ideal gas expands adiabatic from a volume of V1 = 1,00l with its pressure of p1 = 10^5 Pa to 1/10 of its original pressure. What volume V2 (in litres) does the gas reach after it’s expansion? Round to two decimal places

8 / 10

A spring in a car’s suspension has elastic potential energy store 226 J. If the spring constant is 8.1N/mm, find the extension. Give answer in meters to three significant figures.

10 / 10

Calculate the cornering speed during Skidpad (you can use the centerline radius in the rules) using following information:

μ_y = 1.4,  m = 240 kg,  c_L = 3.2,  A = 1 m^2,  ρ = 1.1  kg/m^3

It is assumed, that there is no weight transfer and all 4 tires are at the optimal grip level. Answer in m/s rounded to one decimal place.
