If you use 256cels with a configuration of 64s4p of Sodium-sulfur cells, how many temperature sensors are required:

Imagine you build a car with m = 1500 kg, Af · cd = 0.7 m2 , cr = 0.012. For a speed v = 120 km/h and an acceleration a = 0.027 g, calculate the traction torque required at the wheels and the corresponding rotational speed level (tires 195/65/15T). Calculate the road slope that is equivalent to that acceleration.

What is the penalty attributed to a team who uploads their SESA at 2018-04-14 12:00 CEST?

Your self-developed electronic control module needs 200ms to safely shut down and write back data into nonvolatile memory. How big would the power regulator output capacitance need to be at least to do that in the event of a unexpected shutdown (GLV Master switch turn-off), given that: + The device needs a constant current of 120mA + The regulated voltage is 5V + The CPU will brown-out at 3.8V + There is no reverse-flow back into the supply

Imagine you are working with an EPROM. You have a 4 bit bandwith for adresses and 20 bit words. Which will be the minimum normalized dimension for the EPROM?

A car with 300 kg has a tire longitudinal coefficient of friction given by μx(Fz) = 2,4 – 0,0011Fz, a Cl = 2, frontal area of 1.5m^2 and the air density is 1,225 kg/m^3. In a straight, there is a certain velocity for which ignoring aerodynamic effects is equal to considering them. If this velocity is 25m/s, what is the Cd? (performance always limited by the tire and ignore load transfers)

The IA assembly decelerates the vehicle at constant acceleration, when mounted on a vehicle of 300kg and impacting a barrier at 7m/s. What is the minimum deformation of the IA (plastic deformation only)?

What happens if the driver does an incorrect number of laps in the skidpad event?

If the track conditions change to dry during the skidpad event, a team may change to dry tires. This sentence is:

While simulating a scruteneering, the members of a FS team find out that the their front wing is defleting more than the rules allow. Therefore, the aerodynamics department, without performing any study/simulation, come up with a solution, with horizontal edges, that fixes the problem, but, due to the design of the bodywork, can contact with pedestrians. What should be the minimum radius of this solution?

Your electric motor is capable of 6W at 5000rpm. The output shaft of the motor is connected to a 13 teeth spur gear which is in contact with an output gear with 47teeth. What will be the output speed and output torque? (Your system has 100% efficiency)

Calculate the Tension Safety factor if your accumulator floor walls have the same inner and outer skin thickness = 0.2mm. Consider also that if it holds a maximum force of 6,5KN and 5KN max in the linear domain. Assume a minimum 10mm core thickness.

A car having a mass of 2 Mg strikes a smooth, rigid sign post with an initial speed of 30 km/h. To stop the car, the front end horizontally deforms 0.2 m. If the car is free to roll during the collision, determine the average horizontal collision force causing the deformation.

An accelerometer has a proof mass of 0.001kg and a spring with a constant of 5 x 10^3 N/m. Assume that the maximum displacement of the spring is ± 0.1mm. What is the maximum acceleration which can be measured?

Imagine a system with a mass, a damper and a spring. If m=200kg and K=1000N/m, what must be the damping constant C for the system to reach 2% of it's final position, when excited, in one second?
