Which of the following communication protocols is faster (bytes/sec)?

What is the maximum lateral acceleration that can take a vehicle with the following characteristics? Track width= 0.8 m hCoG=0.3 m µ=1.4

1. Involute function of 10,6 degrees:

One Formula Student car with a track of 780 mm is taking a turn. To do the maneuver the angle rotated by the outer wheel is 0.2269 rad while the angle rotated of the inner wheel is 22/7 times the outer angle. What is the minimum wheelbase that has to have the car?

After a fluid mechanics class where it has been explained the movement of a fluid through a tube, a student interested in the subject decides to make an experiment at home. Therefore, by using the acquired knowledge, he decides to create a cannon where the projectile (ping-pong ball) is boosted by the force that causes the atmospheric pressure. To do it, he takes a PVC tube (Yield strength of 55 MPa) of 1.75 m of length and a section equal to the ball. He inserts the ball inside and seal the ends. The air is removed from the inside of the tube by connecting a vacuum pump. After he breaks the cover of the left end with a sharp object and the air penetrates into the tube and pushes the ball that moves along it until it reaches the other end, breaking the cover and leaving at high speed. The ball hits a small sculpture at a high speed and breaks it. He, curious about the result obtained, intends to apply his knowledge of engineering to find the speed at which the ball has been fired. The ping-pong ball has a mass m = 2.5 g and a diameter of 1.5 inch, the air density is ρ = 1.29 kg/m3 and the atmospheric pressure is p0 = 760 mm Hg.

Two cars are compared, one of 280 kg and another of 380 kg including the driver, regarding the lateral acceleration:

Which is the optimal damping ratio configuration of a shock absorber in the following situations. A: bump ; B: roll,dive. Note: High damping ratio around 0.7-0.8, Low damping ratio around 0.2-0.3.

Regarding the FSG 2018 Rules. Which statement is true?
