A start-up company wants to convert an ICE vehicle into an electric vehicle with the following specification.
Power: 250 (HP) horsepower, (note: 1HP = 745 W)
Range: 300-miles
Fuel economy: 33.5 kilometers per gallon of gasoline.
Efficiency of the ICE: 25%
Energy Conversion: One gallon of gasoline at 100% efficiency is equal to 33.5 kWh/gallon).
a)Calculate the EV consumption rate as Wh/km and find the total energy of the battery pack in KWh to replace the internal combustion engine.
b)Design an 8-module battery pack for this full electric vehicle without compromising its range and performance (power).
Use commercially available cylindrical cells lithium cell with 20Ah capacity and 3.125 V average voltage. Cell dimensions are 5cm diameter and 10 cm height. The electric motor requires 250 V input that will be provided directly from the battery pack, Report the configuration of each module in…

Consider three cases where the body rotates 1 rad/sec about each principal axis. Integrate the resulting motion and study the angular rates and the resulting attitude (use any attitude coordinates). For each principal axis case, assume first that a pure spin about the principal axis is performed, and then repeat the simulation where a small 0.1 rad/sec motion is present about another principal axis. Discuss the stability of each motion.
