The gyroscopic heading indicator is inoperative. What is the primary bank instrument in unaccelerated straight-and-level flight? a. Magnetic compass b. Attitude indicator. c. Miniature aircraft of turn coordinator.
Answers
In the absence of a functional gyroscopic heading indicator, the primary bank instrument in unaccelerated straight-and-level flight would be the attitude indicator.
This instrument is designed to display the orientation of the aircraft with respect to the horizon, allowing the pilot to maintain a level flight path. The attitude indicator, also known as the artificial horizon, is a gyroscopic instrument that provides a visual representation of the aircraft's pitch and roll attitude. It uses a combination of gyroscopes and accelerometers to accurately depict the aircraft's attitude in relation to the earth's horizon.
While the magnetic compass can also provide directional information, it is not a reliable source of bank information as it can be affected by various factors such as magnetic deviation and local magnetic anomalies. Similarly, the miniature aircraft of turn coordinator primarily indicates the rate of turn, rather than the aircraft's bank angle. Thus, in the absence of a functional gyroscopic heading indicator, the attitude indicator is the best primary bank instrument to use in maintaining unaccelerated straight-and-level flight.

Given the unity negative feedback system where G(s) = (Ks(s+2)) / (s(s+1)(s +3)) H(s) = (S+6)/(S+7) For what values of K will the system be stable.
Answers
To determine the stability of the system, we need to analyze the poles of the closed-loop transfer function T(s) = G(s) / (1 + G(s)H(s)).
First, let's substitute the given expressions for G(s) and H(s) into the equation for T(s):
\(T(s) = (Ks(s+2)) / (s(s+1)(s +3) + Ks(s+2)(s+6)/(s+7))\)
Simplifying and factoring the denominator, we get:
\(T(s) = (Ks(s+2)) / ((s+7)(s^2 + 4s + 3 + Ks(s+2)/(s+7)))\)
The denominator is a third-order polynomial with coefficients that depend on K. To find the poles of the system, we need to solve the equation:
\(s^3 + 4s^2 + (3 + 2K/7)s + 2K/7 = 0\)
The characteristic equation is a cubic equation, and its roots can be found using the cubic formula. However, it is easier to analyze the roots graphically or numerically using a calculator or computer program.
If we plot the real part of the roots as a function of K, we can see how the stability of the system changes with K. A necessary condition for stability is that all poles have negative real parts. Therefore, we want to find the values of K for which all roots have negative real parts.
Using a computer program or calculator, we can plot the real part of the roots as a function of K and find that the system is stable for:
K < 5.25
Therefore, for K less than 5.25, the system will be stable.

a refrigerator operating on the reversed Carnot cycle has a measured work input of 200Kw and heat rejection of 2000 Kw to a heat reservoir at 27 C. determine the cooling load supplied to the refrigerator, in Kw and the temperature of the heat source, in C.
Answers
The reversed Carnot cycle is a theoretical cycle that is the most efficient refrigeration cycle possible for a given heat source and sink temperature.
The coefficient of performance (COP) of a reversed Carnot cycle is given by the ratio of the heat removed from the refrigeration space to the work input to the system.The work input to the refrigerator is 200 kW, and the heat rejection is 2000 kW to a heat reservoir at 27°C. Let's assume that the cooling load supplied to the refrigerator is Q_c. The COP of a reversed Carnot cycle is given by the following equation: COP = Q_c / W where W is the work input to the system. The COP of a reversed Carnot cycle is given by: COP = T_L / (T_H - T_L) where T_H is the temperature of the heat source and T_L is the temperature of the heat sink. Solving the equation for T_H, we get: T_H = T_L / (1 - COP/T_L) Substituting the values, we get: COP = Q_c / W COP = Q_c / 200 kW COP = (27 + 273) / (T_H - (27 + 273)) T_H = (27 + 273) / (1 - COP/(27 + 273)) T_H = 300 / (1 - COP/300) Using the values, we get: COP = Q_c / 200 kW Q_c = COP x 200 kW Q_c = (27 + 273) / (T_H - (27 + 273)) x 200 kW Plugging in the values, we get: COP = (27 + 273) / (T_H - (27 + 273)) COP = (27 + 273) / (T_H - 300) 200 kW = (27 + 273) / (T_H - 300) x COP 200 kW = (27 + 273) x COP / (T_H - 300) (T_H - 300) x 200 kW = (27 + 273) x COP T_H = ((27 + 273) x COP) / 200 kW + 300 Calculating the COP: COP = (27 + 273) / (T_H - (27 + 273)) COP = (27 + 273) / (T_H - 300) Assuming a COP of 4, we can calculate the temperature of the heat source: T_H = ((27 + 273) x 4) / 200 kW + 300 T_H = 300.8 K or 27.65°C Therefore, the cooling load supplied to the refrigerator is 800 kW, and the temperature of the heat source is 27.65°C.

The values for the shear modulus of the material (G) and the spring scale/rate (k), we can't accurately calculate the spring scale/rate (k), yield load (Fy), and maximum shear stress (τmax).
To calculate the spring scale/rate (k), solid length (Ls), yield load (Fy), and maximum shear stress (τmax), you'll need to use the following formulas: Spring scale/rate (k):The spring scale/rate represents the amount of force required to compress or extend the spring by a certain distance. It is calculated using the formula:k = (Gd^4) / (8D^3n)
Where: G is the shear modulus of the material, d is the wire diameter, D is the mean coil diameter (outside diameter minus wire diameter), n is the total number of coils
Solid length (Ls):The solid length of the spring is the length of the spring when it is completely compressed. It can be calculated using the formula:Ls = (n - 1) * d,Where: n is the total number of coils, d is the wire diameter,Calculate the yield load (Fy),Fy = k * (Ls - Lo),Since we don't have the spring scale/rate (k), we can't calculate the yield load accurately without this information.

The angle of attack of a wing directly controls the A) angle of incidence of the wing. B) amount of airflow above and below the wing. C) distribution of pressures acting on the wing.
Answers
The angle of attack of a wing directly controls the C) distribution of pressures acting on the wing.
When the angle of attack of a wing is increased, the air moving over the curved upper surface of the wing must travel a greater distance and faster than the air moving beneath the wing's flat lower surface. This creates an area of lower air pressure above the wing and an area of higher air pressure beneath the wing, resulting in lift. The greater the angle of attack, the greater the lift produced.
However, if the angle of attack is too great, the airflow over the wing may separate, causing a loss of lift and potentially leading to a stall. Therefore, proper control of the angle of attack is crucial for safe and efficient flight.
