Answer:
The electrical power is 96.5 W/m^2
Explanation:
The energy balance is:
Ein-Eout=0

if:
Gsky=oTsky^4
Eb=oTs^4
qc=h(Ts-Tα)


if Gl≈El(l,5800)

lt= 2*5800=11600 um-K, at this value, F=0.941

The hemispherical emissivity is equal to:

lt=2*333=666 K, at this value, F=0

The hemispherical absorptivity is equal to:

Answer:
L= 50000 lb
D = 5000 lb
Explanation:
To maintain a level flight the lift must equal the weight in magnitude.
We know the weight is of 50000 lb, so the lift must be the same.
L = W = 50000 lb
The L/D ratio is 10 so
10 = L/D
D = L/10
D = 50000/10 = 5000 lb
To maintain steady speed the thrust must equal the drag, so
T = D = 5000 lb
A safety device called a cotter pin. The cotter pin fits through a hole in the bolt or part. This keeps the nut from turning and possibly coming off.
