Question:
The schematic shows the front upright of a Formula Student car connected to the chassis by an upper and a lower suspension link at points E and G. During cornering, a lateral tire force Fw,y = 1 kN acts at ground level. The vertical distance between the lower joint G and the ground is b = 100 mm, and the vertical separation between the upper and lower joints is c = 200 mm.
Determine the reaction forces in the two suspension links, FE and FG.

Answer in kN and round to one decimal place.

Question:
Formula Student goes to Space!
What SpaceX can do, we can do too. We’re sending a Formula Student car into space.

Consider a rocket with a conical nose, diameter d and opening angle α, moving through the atmosphere with velocity v in air of density ρatm. The thermal motion of the air molecules can be neglected. Due to elastically assumed collisions with the air molecules, a drag force acts on the rocket.
The drag force changes during the flight. The figures show the rocket’s velocity as well as the atmospheric pressure as functions of altitude. The atmospheric temperature is assumed to be constant.
The Earth’s mass is given as ME = 5.97 × 1024 kg and the Earth’s radius as RE = 6.37 × 106 m.
Determine the minimum velocity the rocket must reach at engine cutoff in order to achieve a low Earth orbit. Also determine the orbital period.
Round to one decimal places. Answer in kilometres per second and minutes separated by a semicolon.

Question:
Unfortunately, the engine was switched off too late, and instead of an Earth orbit, we have now reached a solar orbit.

Assume now that the race car orbits the Sun along a path with a radius equal to the average Earth–Sun distance of approximately 1.5⋅10^11m. The race car is far away from the Earth and all other celestial bodies. The mass of the Sun is approximately mS=1.99⋅10^30kg, and the radius of the Sun can be assumed to be very small compared to the Earth–Sun distance.
Now we stop the race car completely relative to the Sun.

How long will it take for the race car to fall into the Sun?

Round to the nearest whole day.
