Practice Questions

Question 1

Which of the following is the primary function of brake ducts in performance braking systems?

Question 2

If a brake rotor has a mass of 8 kg with specific heat capacity $c=500\ \mathrm{J/(kg\cdot K)}$ and it absorbs 0.8 MJ of heat, what is the approximate temperature rise $\Delta T$?

Question 3

For a vehicle with mass 1200 kg, center-of-gravity height 0.55 m, wheelbase 2.5 m, and deceleration $a=8\ \mathrm{m/s^2}$, what is the dynamic load transferred to the front axle?

Question 4
