1. Your head of powertrain has found a battery cell with excellent specifications and yet cheap. He decides upon a 142s2p accumulator configuration using the cells with a capacity of 5.8 Ah. The manufacturer specifies an internal impedance of 1.5 mOhm. However, after a while you notice the cells are of horrible quality and their real capacity varies significantly leading to an unbalanced accumulator.

He performed experiements to find an approximation of the cells SoC relation to their open-circuit voltage (EMF) as shown in the following figure:

Assume due to imbalance, exactly half of the accumulators cells are at 40% SoC and half at 80% SoC. What current will be drawn at the maximum allowed power usage? Give answer in Amps to nearest whole number

Quiz „General Engineering“

1.

A metal piece heated to θ_1,M=1000∘C with a mass of M_M=6.5 kg was cooled in a completely heat-insulated iron container filled with water. The mass of the water in the container is M_W=10 kg and the mass of the container is M_B=2 kg. The initial temperatures of the water and the container were the same and amounted to θ_1,W=10∘C. After complete thermal equilibrium between the immersed metal piece, the water, and the container, a temperature of θ2=80∘C was established.
What is the average specific heat capacity of the metal piece cc in the temperature range between 80∘C and 1000∘C?

Input the result in kJ/(kg*K), round to 3 decimal numbers sperated by a point (example: 0.136).

2 / 10

2. For a horizontally positioned, non-insulated steam pipe with a length of l=3 m and a diameter of d_a=0.1 the convective heat loss Q_point is to be calculated. The temperature of the surrounding air is θ_f=30∘C and that of the outer wall surface is θ_w=170∘C.

Input the result in kW and round to two decimal numbers seperated by a point without thr unit (example: 145.35)

3. A helicopter of mass 4200 kg is carrying a crate using a light extensible rope. The crate has a total mass of 800 kg, including its contents. The helicopter and crate are accelerating upwards at 2.0 ms^-2. What is the tension in the rope? Use gravititational field strength g is 9,81 N/kg. Air resistance can be ignored. Give answer to nearest whole number in Newtons

4 / 10

4. A racing car rolls to a stop on a horizontal course with an initial speed of v. It decelerates
only by friction with a rolling resistance of μF, which is supposed to be independent of
the current velocity.
What is the distance s the car needs to stop?
v = 300 km/h, μF = 0.15, g = 9.81 m/s2.
Give your answer in meters, rounded to four significant places.

5 / 10

5. The previous season you could recuperate only 25% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 63% of the initially stored energy.  Knowing that you had 9.6 kWh of energy in your accumulator during the last season, how much energy must your new accumulator have, if you assume, that it’s the same length and speed? Give answer in kWh to one decimal place.

10. During last year acceleration a top speed of 100 km/h was reached. Due to big improvements in the new drivetrain, the new vehicle reaches a top speed of 120 km/h. The aerodynamics chief has some worries about the stability of the rear wing bracing due to the higher aerodynamics load. Given the geometry below, by how much % does the bearing force in point A change in comparison to last year? (The aerodynamic package did not change and therefore some values can be assumed for both vehicles). Give answer rounded to one decimal place.

CL=3.8     CD=1.2     A=1 m²     rho=1.1 kg/m³     L1=50 mm     L2= 100 mm     H1= 125 mm     H2= 165mm
