In the ungrounded electrical circuits or systems, the circuit is one that is not  or do not have the connection to the grounding electrode.

<h3>What is an ungrounded electrical system?</h3>

An ungrounded system is known to be defined as a system that is known to be one that do not have an intentional connection to ground, and it has an exception of possibly going through potential indication or other kinds of devices.

Note that The neutral of an ungrounded system is one that is seen to be under reasonably balanced load conditions and thus it is one that is usually near to ground potential.

Hence, In the ungrounded electrical circuits or systems, the circuit is one that is not  or do not have the connection to the grounding electrode.

A circular bar will be subjected to an axial force (P) of 2000 lbf. The bar will be made of material that has a strength (S) of
schepotkina [342]

Answer:

n = 2.36

Explanation:

The stress experimented by the circular bar is:

\sigma = \left[\frac{2000\, lbf}{\frac{\pi}{4}\cdot (0.5\,in)^{2}}\right]\cdot \left(\frac{1\,kpsi}{1000\,psi} \right)

\sigma = 10.186\,kpsi

The safety factor is:

n = \frac{24\,kpsi}{10.186\,kpsi}

n = 2.36

What are some aircraft aging problems? How can you as an Aviation Maintenance Manager monitor problems that relate to aircraft f
julia-pushkina [17]

Answer:

Answered

Explanation:

The two key processes that lead to aircraft ageing are fatigue and corrosion. These processes generally affect the aircraft structure, but can also affect wiring, flight controls, power plants, and other components. Fatigue and corrosion can work independently from one another, or they can interact. The interaction between fatigue and corrosion can increase the rate of ageing to a greater extent than that due to either process alone.

Fatigue predominately takes place in metal components, but it can also affect non-metallic materials. Fatigue occurs through cyclic loading patterns, where a component is repeatedly loaded. Bending a metal paper clip backwards and forwards is an example of fatigue; the paper clip will not break if only bent once, however, if it is repeatedly loaded, it will eventually break. Fatigue failures will often take place at loads much lower than the materials ultimate strength.

Generally, the initiation point for fatigue will be a microscopic crack that forms at a location of high stress, such as a hole, notch, or material imperfection. The crack will then grow as loads are repeatedly applied. If not detected and treated, the crack will eventually grow to a critical size and failure will occur at loads well below the original strength of the material.

The relationship between repetitive loading and fatigue crack growth, creates a link between fatigue related ageing, the number of flight cycles, and the number of flight hours that an aircraft has accumulated.

Aircraft components that are susceptible to fatigue include most structural components such as the wings, the fuselage, and the engine.

During initial manufacturing the research department is responsible for designing the aircraft to withstand fatigue. During operations the fatigue risk management of aviation maintenance will try to rectify the problems due to fatigue.

A velocity field is given by V=(2x)i + (yt)j m/s, where x and y are in meters and t is in seconds. Find the equation of the stre
lesya692 [45]

Answer:

Equation of the streamline V = 4i - 4j m/s

Unit Vector n = (4i+4j)/4√2

Explanation:

Parameters

x=2 and y=-1

V=(2x)i + (yt)j m/s

Substituting (x=2) and (y=-1) into the velocity field V

Therefore V = 4i - tj  where t=4s

Equation of the streamline

V = 4i - 4j m/s

Unit vector normal to the streamline n

Note V.n=0 and the velocity only have x- and y - components

Therefore

V.n=(4i - 4j).(nₓi+nyj)=0 or 4nₓ -  4ny = 0

The unit vector requires that nₓ^2+ny^2=1

Therefore n = (4i+4j)/4√2
