State the electrical ratings using voltage, phases, number of wires, current and frequency. (a) If you have single-phase electrical utilization equipment that can be powered from either 208 V or 240 V in North America, or 230 V in Europe, and draws 10 A, what would the electrical rating be? (b) Is it necessary to say the number of phases?

Long-Period Approximation of Longitudinal Motion
(Phugoid)Consider an example aircraft flying at low-speed:
ft/s2000=u, assuming unpowered (gliding)flight, and neglecting
compressibility effects, with 0.0061 / suX= − and 0.322 / suZ= −.
The long-period approximation of aircraft motion yields the
following equation:
Find the natural frequency and damping ratio of the system.
(note: for unit-consistency, you must expressg in ft/s2).

An aircraft system is modeled as being comprised of (3) independent subsystems - each critical - with reliability as follows : – Electrical => 15% probability of failure – Mechanical/Hydraulic => 10% probability of failure – Fuel/Powerplant => 5% probability of failure Question 1: What is the overall reliability of the aircraft system? Two identical Electrical subsystems are installed side-by-side in a hot-swap backup configuration. Question 2: Assuming all independent subsystem components have the same reliability as previously stated, what...

1. What is the relationship between angular speed, frequency, and period? 2. The generator equation is EMF = ωNBA sin(ωτ). In terms of this equation and your own observations, explain why the maximum induced EMF is + ωNBA. 3. Imagine that a not so benevolent dictator of a small nation has decided to increase his country’s electrical output by increasing the speed of the generators in its single electrical plant. Discuss the result in terms of the generator equation.
