Calculate the Normal force on the rear left tyre during the first skidpad lap. You can assume, that your vehicle is in a steady-state condition and that there is no longitudinal acceleration. Further it can be assumed, that all 4 wheels have a lateral grip coefficient of 1.4. You can use the centerline radius stated in the rules. Following information regarding the vehicle are given. Give answer to nearest whole number in Newtons.

 

m = 220 kg

Cl = 3.8

A = 1 m^2

Rho = 1.1 kg/m^3

Wheelbase: L = 1.53

Trackwidth:t = 1.2 m

Height of CG: h = 0.2 m

Weight distribution/COP: 50%

9 / 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.

10 / 10

The previous season you could recuperate only 25% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 63% of the initially stored energy.  Knowing that you had 9.6 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 to one decimal place.
