FSG Preparation
1. You built a cannon to impress your friends with a basketball trickshot. It has a railgun-style accelerator with a length / of 1 m. Your cannon is tilted upwards by an angle a of 77.25° and is placed as depicted with the lower part in the origin of the coordinate system. The cannonball has a mass m of 0.567 kg. Assume that the capacitors have a total capacity C of 33 mF, that the standard acceleration due to gravity 9, is 980.665 cm/s^2 and that there is no friction and no energy loss. What voltage do you need to charge the capacitors supplying the railgun to, in order to hit the basket at (4.191 m, 3.05 m). Round to the nearest one.
2. For the shown drive train, the input rotational speed is 3600 min-1, and the number of teeth of the sprocket is z1 = 20. ease note: n2 = n3, n4 = n5, n6 = n7. The number of teeth of the sprockets are: z1 = 20, z2 = 45, z3 = 24, z4 = 55, z5 = 30, z6 = 43, z7 = 15, z8 = 53 Calculate the rotational speed in min^-1 for the final sprocket z8 where the driveshafts are mounted. Round to one decimal.
The figure shows a simplified quarter vehicle modal. The drive torque T(M) is the input, the wheel speed W is the output of the system. The torque due to the acceleration of the vehicle is modelled by the constant disturbance d. I models the inertia of the wheel and s is the complex variable of the Laplace transform.
Which statements are correct? Mark all correct answers.
4. Fred, the racing alpaca, challenges Coco, the 3-leged cat, to an acceleration event according to D 5.1.1. Being very confident, Fred gives Coco a head start h of 14 m infront of the start line. Both start the same time t=0 s having an initial speed V0 of 0m/s as shown in the figure. Coco accelerates with 6m/s^2. Assume that both are not limited by speed and have a constant acceleraton over the full acceleration event.

5. Consider a digital LVTTL signal from your pedalbox to your main control unit. The length / of the cable inbetween is 5m. Your motor controllers introduce a noise of 0.15 V per meter cable. To correct for that noise, you introduce 74LVC1G34, non-inverting buffers into the cable. The purpose of the buffer is to take a signal, to which a certain amount of noise has been added so that it would no longer meet the input specification of the static discipline, and clean it up so that it once again meets the output specification of the static discipline. The non-inverting LVTTL buffers, as well as the gates shown, obey the following static discipline:

1. Which of the following requirements of the brake light assembly must be met to be rules compliant? (multiple choice)
See FSG rules 2023: T6.3
2. A thin circular, isolated wire made of copper with radius R lies on a table with its ends connected to a Volt meter. Another, straight wire lies exactly along a diameter of the circular wire, connected to an alternate current source i(t) = I0 sin(wt). The experimental setup is shown in the following Figure:
Which effective voltage Ueff does the Volt meter display? R = 10 cm, maximum current I0 = 1 A, f = 50 Hz. Give your answer in Volts with three decimal places
The magnetic field lines H around the straight, current-carrying wire run in concentric circles, with their centres lying on the wire axis. The field lines thus enter the wire perpendicularly in one half of the circle and leave it perpendicularly in the opposite half. This means that one semicircle of the induction loop is penetrated by the time-varying magnetic flux (t), while the opposite semicircle is penetrated by exactly the opposite flux -(t) for reasons of symmetry. The total flux at any time is zero at all times, which means that no induction voltage and thus no effective voltage Ueff is indicated at any time. The specification of the data in the task was therefore completely superfluous.

9. You would like to drink a cup of very hot coffee with milk early in the morning, but you are in a hurry and have only 5 minutes until you have to leave for work. At which time after brewing should you add the cold milk to the coffee and stir in order to decrease the temperature of the mixture as much as possible: a) 0 minutes (immediately), b) 2 minutes, or c) 4 minutes? Suppose that the stirring can be done instantaneously and that you need the last one minute for drinking.
brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature 0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).
Please enter only the letter of the corresponding answer
The driving „force“ for the cooling of the coffee is the temperature difference between the warm coffee and the environment (room temperature), which leads to an exponential drop in coffee temperature. The temperature difference is greatest immediately after brewing. The later we stir in the milk, the lower the coffee temperature has already dropped. On the other hand, lowering the temperature by the milk becomes smaller the longer we wait. So we let the coffee cool down on its own for as long as possible in order to bring about the temperature reduction by the cold milk at the end. The greatest possible cooling is therefore achieved when the milk is added after 4 minutes.
