A jet transport has a weight of 1.87 x 10⁶ N and is at rest on the runway. The two rear wheels are 16.0 m behind the front wheel

qwelly [4]

Answer:

a) R(fw) = 46.75*10⁶ (N)

b) R(rwi) = 70.125*10⁶ [N]

Explanation: See Attached file (the rectangle stands for a jet)

The diagram shows forces acting on the jet

Let R(fw) Reaction of front wheels and

R(rw) Reaction of rear wheels

Now we apply the Stevin relation, for R(fw) and a jet weight as follows

R(fw)/ 4 = 187*10⁶ / 16

Then :

R(fw) = ( 1/4) *187*10⁶ ⇒ R(fw) = 46.75*10⁶ (N)

And e do the same for the reaction on rear wheels

R(rw) / 12 = 187*10⁶ /16 ⇒ R(rw) =(3/4)*187*10⁶

R(rw) = 140,25*10⁶ [N]

The last expression is for the whole reaction, and must be devide by 2

because that force is exerted for two wheels, therefore on each of the two rear wheels the reaction will be:

R(rwi) = 70.125*10⁶ [N]

The earth rotates once per day about an axis passing through the north and south poles. True or False

alexandr402 [8]

Answer: False.

Explanation: The Earth rotates once per day in direction from East to West. The rotation of the Earth daily is responsible for day and night experienced, the areas of the Earth facing the Sun experiences day time while the areas of the Earth away from the Sun in the Earth's shadow experiences night time.

While the revolution of the Earth around the gives rise to a year, as it takes 365 days for the Earth to go round the sun.

an electric device is plugged into a 110v wall socket. if the device consumes 500 w of power, what is the resistance of the devi

andreev551 [17]

Answer: R=24.2Ω

Explanation: Power is rate of work being done in an electric circuit. It relates to voltage, current and resistance through the following formulas:

P=V.i

P=R.i²

$P=\frac{V^{2}}{R}$

The resistance of the system is:

$P=\frac{V^{2}}{R}$

$R=\frac{V^{2}}{P}$

$R=\frac{110^{2}}{500}$

R = 24.2Ω

For the device, resistance is 24.2Ω.
