What is a Ramjet engine?

1 answer:

8 0

Hi,

A Ramjet engine is a type of jet engine. There are four kinds of jet engines: Rocket Jet, Ramjet, Pulsejet, and Turbine Jet.

By definition, a Ramjet engine is a type of jet engine in which the air drawn in for combustion is compressed solely by the forward motion of the aircraft.

A 450.0 N, uniform, 1.50 m bar is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tensi

bogdanovich [222]

Answer:

1) $W_{object} = 400 N$

2) x = 0.28 m from cable A.

Explanation:

1 ) Let's use the first Newton to find the , because bar is in equilibrium.

$\sum F_{Tot} = 0$

In this case we just have y-direction forces.

$\sum F_{Tot} = T_{A}+T_{B}-W_{bar}-W_{object} = 0$

Now, let's solve the equation for W(object).

$W_{object} = T_{A}+T_{B}-W_{bar} = 550 +300 - 450 = 400 N$

2 ) To find the position of the heaviest weight we need to use the torque definition.

$\sum \tau = 0$

The total torque is evaluated in the axes of the object.

Let's put the heaviest weight in a x distance from the cable A. We will call this point P for instance.

First let's find the positions from each force to the P point.

$L = 1.50 m$ ; total length of the bar.

$D_{AP} = x$ ; distance between Tension A and P point.

$D_{BP} = L-x$ ; distance between Tension B and P point.

$D_{W_{bar}P} = \frac{L}{2}-x$ ; distance between weight of the bar (middle of the bar) and P point.

Now, let's find the total torque in P point, assuming counterclockwise rotation as positive.

$\sum \tau = T_{B}(L-x)-T_{A}(x)-W_{bar}(\frac{L}{2}-x) = 0$

Finally we just need to solve it for x.

$x = \frac{T_{B}L-W_{bar}(L/2)}{T_{B}+W_{bar}+T_{A}}$

$x = 0.28 m$

So the distance is x = 0.28 m from cable A.

Hope it helps!

Have a nice day! :)

Um chuveiro C e um forno de micro-ondas M são ligados, como não há circuito a seguir.

uysha [10]

Responder:

50A

Explicación:

Dado que el Um chuveiro y el microondas están conectados en paralelo, el mismo voltaje fluirá a través de ellos.

La potencia total consumida por ambos aparatos = 4800W + 1200W

La potencia total consumida por ambos aparatos = 6000W

Para obtener el I actual, usaremos la fórmula;

P = IV

6000 = 120I

Yo = 6000/120

Yo = 50 A

Por lo tanto, la medición de corriente del amperímetro ideal A será 50A

umka21 [38]

Answer:

150N

Explanation:

To find the force applied remember that force equals to Mass multiply by the Acceleration.

F=Ma

=30*5

=150N
