A free-piston linear generator consists of two opposite pistons that drive a small magnet through a 100-turn coil with a radius of 10cm that acts as the stator. If the Magnetic Flux Density of the moving part of the generator is given as 𝝵(𝑟,𝑡)=45∗𝑟∗cos(𝑡) where r is the distance from the generator axis, calculate the RMS value of the EMF that is induced on the coil that surrounds the magnets. Answer is rounded up to the second decimal. The device depicted is for reference only.

The AIP Test for anything else than 4.0mm aluminum or 1.5mm steel must be proven by a physical test which requires the AIP to be attached to a test fixture that has geometry, stiffness and strength representative of the intended chassis.
If the front hoop is inclined more than 20° to the rear, additional braces extending rearwards are required.
A composite panel with fiberglass reinforcement can only be used in the TS Accumulator if its matrix is a UL94V0 compliant polymer.
The principle of dynamically induced emf is utilized in an electric generator.
A car and a truck are both travelling with a constant speed of 25 m/s on a narrow road. The car is 15m behind the truck. The truck driver suddenly applies his brakes, causing the truck to decelerate at a constant rate of 3m/s^2. Two seconds later the driver of the car applies his brakes and marginally manages to avoid a rear-end collision. What is the constant deceleration of the car? Answer is rounded to the first decimal.
3.33 m/s^2
2 m/s^2
4 m/s^2
4.33 m/s^2
Sand is continuously thrown into a moving plane as shown in the picture. The plane has a constant speed u as force F is applied to keep it constant. Calculate the power dW/dt , where W is the work from force F when dK/dt=2565 J/s.

Choose the true statements.
Opening of the SDC must be done without the influence of any programmable logic in case of an insulation failure and must be reset manually by the ESO.
All electrical safety items must have a withstand voltage of at least the max TS voltage.
If the front wing's main flap is wider than the front track, it's max cord length is 62.5 cm when placed at a null angle of attack.
All holes and cuts on the chassis must be taken into account for the 2020 SES.
The ballistic pendulum is a device for measuring the velocity u of a bullet of mass m. It consists of a large wooden block of mass M which is supported by two vertical cords. When the bullet is fired at the block, it is dislodged and the block is set in motion reaching maximum height h. If M=6 Kg , m=1 Kg , h=35 cm calculate the speed of the bullet in m/s.
