Consider a light, single-engine airplane such as the Piper Super Cub. If the maximum gross weight of the airplane is 7780 N, the

wing area is 16.6 m2, and the maximum lift coefficient is 2.1 with flaps down, calculate the stalling speed at sea level?

Answer:

V=19.08 m/s

Explanation:

Airplane gross weight w=7780 N

Airplane wing area S=16.6 m²

Air density p=1.2250 kg/m³

Maximum lift coefficient CL=2.1

To find

Stalling Speed

Solution

The equation to find stalling speed is given below

W=(1/2)S_{area}(V_{Stalling-speed} )^{2} (P_{Air-density} )(C_{Lmax} )\\ so\\V_{Stalling-speed}=\sqrt{\frac{2W}{S_{area}*(P_{Air-density} )(C_{Lmax} )} }\\V_{Stalling-speed}=\sqrt{\frac{2*7780}{16.6*2.1*1.225} }\\  V_{Stalling-speed}=19.08 m/s

As more and more bulbs are connected in series to a flashlight battery, what happens to the brightness of each bulb? Assuming th
balu736 [363]

Answer:

P_1 = P_2 = \frac{P}{2}

so each bulb brightness becomes half of its given or indicated power

P_1 = P_2 = \frac{V^2}{R}

so both bulb will glow same power as indicated

Explanation:

Let the indicated power on the bulbs is given as P and its rated voltage is V

so here resistance of each bulb is given as

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

now if the two bulbs are connected in series so we will have

R_{eq} = R_1 + R_2

R_{eq} = 2\frac{V^2}{P}

now the current in the circuit is given as

i = \frac{V}{R_{eq}

i = \frac{P}{2V}

now brightness of each bulb is given as

P_1 = P_2 = i^2 R

P_1 = P_2 = \frac{P}{2}

so each bulb brightness becomes half of its given or indicated power

Now if the two bulbs are connected in parallel

then the net voltage across each bulb is "V"

so we will have

P_1 = P_2 = \frac{V^2}{R}

so both bulb will glow same power as indicated

A hydraulic jack has a small piston area A1 = 2 m^2 and the large piston area A2 = 20 m^2. A 1500 Kg car needs to be lifted. a)
Alex777 [14]

Answer:

1471.5 Newton

10

Explanation:

Small piston area = A₁ = 2 m²

Large piston area A₂ = 20 m

m = Mass of car = 1500 kg

g = Acceleration due to gravity = 9.81 m/s²

Force

F = mg = 1500×9.81 = 14715 N

Force applied by car is 14715 N

a) Pascal's law

\frac{F_1}{A_1}=\frac{F_2}{A_2}\\\Rightarrow F_1=F_2\frac{A_1}{A_2}\\\Rightarrow F_1=14715\frac{2}{20}=1471.5

Force required is 1471.5 Newton

b) Mechanical advantage

\frac{F_2}{F_1}=\frac{14715}{1471.5}=10

Mechanical advantage is 10
