Antilock brake systems are highly effective in stopping a vehicle driving over loose snow.A. TrueB. False

Answer:

R = 20Ω

L = 0.1 H

C = 1 × 10⁻⁵ F

Explanation:

Given the data in the question;

Vs = 10∠30°V   { peak value }

V"s\(_{rms\) = 10/√2 ∠30° V

resonance freq w₀ = 10³ rad/s

Average Power at resonance Power\(_{avg\)  = 2.5 W

Q = 5

values of R, L, and C = ?

We know that;

Power\(_{avg\) = |V"s\(_{rms\)|² / R

{ resonance circuit is purely resistive }

we substitute

2.5 = (10/√2)² × 1/R

2.5 = 50 × 1/R

R = 50 / 2.5

R = 20Ω

We also know that;

Q = w₀L / R

we substitute

5 = ( 10³ × L ) / 20

5 × 20 = 10³ × L

100 = 10³ × L

L = 100 / 10³

L = 0.1 H

Also;

w₀ = 1 / √LC

square both side

w₀² = 1 / LC

w₀²LC = 1

C = 1 / w₀²L

we substitute

C = 1 / [ (10³)² × 0.1 ]

C = 1 / [ 1000000 × 0.1 ]

C = 1 / [ 100000 ]

C = 0.00001 ≈ 1 × 10⁻⁵ F

Therefore;

R = 20Ω

L = 0.1 H

C = 1 × 10⁻⁵ F

The maximum pressure would be 1720 * 2 = 3440 pa (gage).

To determine the length of the clear plastic piping needed for your piezometer, you need to consider the maximum expected pressure and the normal operating pressure of the pipe. If the normal operating pressure is 1720 pa (gage), and you expect the maximum pressure to be double that value, then the maximum pressure would be 1720 * 2 = 3440 pa (gage). The length of the piping will depend on the pressure rating of the plastic piping, which should be specified by the manufacturer. If the plastic piping is rated for 3440 pa (gage), you would need a piece that is long enough to reach the desired measurement location. If the piping is not rated for 3440 pa (gage), you would need to use a higher-rated piping or add reinforcement to the piping to ensure it can handle the maximum expected pressure.

A large tower is to be supported by a series of steel wires. It is estimated that the load on each wire will be 11,100 N.

Determine the minimum required wire radius assuming a factor of safety of 3 and a yield strength of 1500 MPa.

answer in mm please

Answer:

the minimum required wire radius is 5.3166 mm

Explanation:

Given that;

Load F = 11100N

N = 3

∝y = 1500 MPa

∝workmg = ∝y / N = 1500 / 3 = 500 MPa

now stress of Wire:

∝w = F/A

500 × 10⁶ = 11100 / A

A = 22.2 × 10⁻⁶ m²

so

(π/4)d² = A

(π/4)d² = 22.2 × 10⁻⁶

d² = 2.8265 × 10⁻⁵

d = 5.3165 7 × 10⁻³ m³

now we convert to mm(millimeters)

d = 5.3166 mm

Therefore the minimum required wire radius is 5.3166 mm

If a standard-weight steel pipe of 12-in. nominal diameter carries water under a pressure of 440 psi then the maximum tensile stress in the pipe is 7040 psi.

To determine the maximum tensile stress in the steel pipe, we can use the formula for hoop stress in a cylindrical pressure vessel. The hoop stress (σ_h) is given by:

σ_h = P * D / (2 * t)

where:

P = Pressure inside the pipe

D = Inside diameter of the pipe

t = Wall thickness of the pipe

Given:

Pressure (P) = 440 psi

Inside diameter (D) = 12 inches

Wall thickness (t) = 0.375 inches

Converting the inside diameter to feet and the wall thickness to feet:

D = 12 inches = 1 foot

t = 0.375 inches = 0.03125 feet

Substituting the values into the formula:

σ_h = (440 psi) * (1 foot) / (2 * 0.03125 feet)

= 440 psi / 0.0625

= 7040 psi

Therefore, the maximum tensile stress in the steel pipe is 7040 psi.

Answer:

When are resistors in series? Resistors are in series whenever the flow of charge, called the current, must flow through devices sequentially. For example, if current flows through a person holding a screwdriver and into the Earth, then  

R

1

 in Figure 1(a) could be the resistance of the screwdriver’s shaft,  

R

2

 the resistance of its handle,  

R

3

 the person’s body resistance, and  

R

4

 the resistance of her shoes.

Figure 2 shows resistors in series connected to a voltage source. It seems reasonable that the total resistance is the sum of the individual resistances, considering that the current has to pass through each resistor in sequence. (This fact would be an advantage to a person wishing to avoid an electrical shock, who could reduce the current by wearing high-resistance rubber-soled shoes. It could be a disadvantage if one of the resistances were a faulty high-resistance cord to an appliance that would reduce the operating current.)

Two electrical circuits are compared. The first one has three resistors, R sub one, R sub two, and R sub three, connected in series with a voltage source V to form a closed circuit. The first circuit is equivalent to the second circuit, which has a single resistor R sub s connected to a voltage source V. Both circuits carry a current I, which starts from the positive end of the voltage source and moves in a clockwise direction around the circuit.

Figure 2. Three resistors connected in series to a battery (left) and the equivalent single or series resistance (right).

To verify that resistances in series do indeed add, let us consider the loss of electrical power, called a voltage drop, in each resistor in Figure 2.

According to Ohm’s law, the voltage drop,  

V

, across a resistor when a current flows through it is calculated using the equation  

V

=

I

R

, where  

I

 equals the current in amps (A) and  

R

 is the resistance in ohms  

(

Ω

)

. Another way to think of this is that  

V

 is the voltage necessary to make a current  

I

 flow through a resistance  

R

So the voltage drop across
