Let’s assume a horizontal plate with length many times greater than width. Air is hitting at this plate with a speed of 48km/h. Air has ideal properties and a density of ρ=1.2kg/m^3 with μ=1.725*10^(-5) N*s/m^2 at the temperatures concidered. Assume that the air becomes turbulent for Re>5*10^5. Which is the thickness of the boundary layer at x=800mm? For turbulent boundary layer assume δ=0.37*x/Re^(0.2) while for laminar use the solution of Prandlt. Round to the nearest int in mm.

A rules compliant non-welded joint may be
A double-lug joint with each lug at least 3 mm thick and bolts being 10 mm metric grade 9.8 minimum.
A double-lug joint with each lug at least 4.5 mm thick and bolts being 10 mm metric grade 9.8 minimum. A double-lug joint with each lug at
A sleeved joint with minimum length of each sleeve 30 mm and 6 mm metric grade 8.8 minimum.
A sleeved joint with minimum length of each sleeve 30 mm and 6 mm metric grade 8.8 minimum.
Yo-yo is made from two uniform disks with mass m and radius R = 3cm, connected by a very light axle of radius b = 2cm. A light, thin string is wound several times around the axle and then held stationary while the yo-yo is released from the rest, dropping as the string unwinds. What is the linear acceleration of the yo-yo? Round to the nearest tenth. (m/s^2)
Which statement regarding the brake system are false
All parts of the brake pedal must be fabricated from steel or aluminum or machined from steel, aluminum or titanium
Brake by wire systems are prohibited in case the vehicle is driving autonomously
The vehicle must have effective braking on all four wheels
The brake system must be able to withstand a load of 1kN applied to the pedal
The first 90% of the brake value of the brake pressure sensor value may be used to regenerate brake energy without actuating the hydraulic brake system
Consider a Formula Student team with an accumulator container made of composite materials. The team uses LiPo cells with maximum voltage of 4.2V and nominal voltage of 3.7V. The configuration is 100s3p. The total capacitance of the bypass capacitors of the motor controllers is 910uF. What is the maximum resistance that can be measured between TS+ and TS- with the TS off. Round to the nearest int in kΩ
Which of the following statements about the Dynamic events are true?
During the electrical inspection, only four members except the ESO may be present at the inspection area.
A team may change a set of tires from the brake test to the acceleration event.
The acceleration track must be 5m wide
The straights at the endurance and autocross track are not longer than 75m
Overtaking a vehicle that is stopped on track, is allowed when there is no red flag from a track marshal, and only in passing zones.
During the driver change, if the second driver cannot enable the TS in two minutes from his first try, the team cannot score more than 575 points at the competition.
Assume a steal beam with square cross section under a point load at mid span. The length of the beam is 1m, the load is equal to 43kN and the maximum deflection of the loaded beam is 0.535mm. Also assume 210000 MPa as Young's Modulus for steel. Define the width of the cross section. (Round to the nearest int at mm)
Screenshot_2
An accumulator container consists of 6 stacks connected in series. Each stack has a 21s2p configuration. The maximum cell voltage is 4.2V, the nominal voltage is 3.75V and the minimum cell voltage is 3V while the nominal capacity of each cell is 6Ah. What is the max value that can be set for triggering the BSPD? (Round to the nearest tenth )
An EV team has qualified to the BP and Cost event finals. At the skidpad event, the team ran all four runs, where the corrected elapsed time of the best one was 5.10 seconds with one DOO, and the best corrected elapsed time was 4.86 seconds. For the rest events, the team scored the 71% of the maximum points it could. Which would be the overall place of the team, for the FSG 2018 EV class?
