Question: find the propeller tip velocity in miles per hour if...

Question details
  1. Find the propeller tip velocity (in miles per hour) if the following parameters are used:
  • Propeller diameter = 9”
  • RPM = 8200

5. A 10 ohm resistor draws 2 amps. What power does the resistor dissipate?

  • 7. If a LiPo battery is labeled as a 4S 70C battery, which of the following would be true?
  • The maximum current is 4 Amps
  • The rated voltage is 14.8V
  • The maximum operating temperature is 70 degrees Celsius
  • The rated voltage is 4V

9. A plate with a surface area of 5” is secured to a table while 1 motor is attached uniformly to it. Once joined, the motor is activated, supplying its full thrust of 2300 Grams. Assuming the force of the motor’s thrust is uniformly distributed across chassis, what stress (pressure) does the frame experience in Pascals?

10. Some 4S LiPo batteries are connecting as shown below. For each setup answer

For the parallel battery configuration, what is the total net Voltage at the outputs (orange circles)?

Note: 4S = 14.8V

Answer:

For the series battery configuration, what is the total net Voltage at the outputs (blue circles)?

Note: 4S = 14.8V
