You are designing a highway to AASHTO guidelines on rolling terrain where the design speed will be 65 mi/h. At one section, a 1.25% grade and a -2.25% grade must be connected with an equal-tangent vertical curve. Determine the minimum length of curve to meet SSD requirements

Answers

Answer 1

The minimum length of the curve meeting the SSD requirements is 643.72 ft.

What is SSD?

The Stopping Sight Distance (SSD) is the smallest sight distance that is accessible to a driver on a highway at any location long enough to allow the driver to safely stop a vehicle driving at design speed without colliding with any other obstruction.It is a crucial component in traffic engineering.The formula for SSD is given as, [tex]SSD=vt+\frac{v^{2} }{2g(f \pm \frac{n}{100}) }[/tex]

From the given question, we have the grades, [tex]g_{1}=+1.25%[/tex], [tex]g_{2}=-2.25%[/tex], and the design speed, [tex]v=65[/tex] mi/h

So, [tex]SSD=vt+\frac{v^{2} }{2g(f \pm \frac{n}{100}) }\\\implies SSD=1.47(65)(2.5)+\frac{65^{2} }{30(0.347826 \pm \frac{1.25}{100}) }\\\implies SSD=630'[/tex]

The length of the vertical curve is given as, [tex]L=2(SSD)-\frac{2158}{A}[/tex]

When SSD>L, we have\

[tex]L=2(630)-\frac{2158}{-2.25-1.25}\\\implies L=1876.57 ft[/tex]

When SSD<L, we have

[tex]L=\frac{A(SSD)^{2} }{2158} \\\implies L=\frac{(-2.25-1.25)(630)^{2} }{2158} \\\implies L=643.72 ft[/tex]

Hence, the minimum length of the vertical curve is 643.721 ft.

Answers

Answer:

The correct answer will be "1477.84 N".

Explanation:

Given that,

Mass,

m = 1.6 mg

or,

   = 1600 kg

Initial velocity,

u = 72 km/h

  = [tex]72\times \frac{5}{18} \ m/s[/tex]

  = [tex]20 \ m/s[/tex]

Final velocity,

v = 18 km/h

  = [tex]18\times \frac{5}{18}[/tex]

  = [tex]5 \ m/s[/tex]

Covered distance,

s = 250 m

By using the below relation, we get

⇒  [tex]v^2=u^2+2as[/tex]

On putting the values, we get

⇒  [tex](5)^2=(20)^2+2\times a\times 250[/tex]

⇒      [tex]a=-0.75 \ m/s^2[/tex] (shows the deceleration)

Slope will be given as 1 in 25, then

⇒  [tex]Sin \theta=\frac{1}{25}[/tex]

           [tex]\theta=2.3^{\circ}[/tex]

hence,

As we know,

⇒  [tex]\Sigma F=ma[/tex]

or,

⇒  [tex]Braking \ force+350-mgSin\theta=ma[/tex]

⇒  [tex]Braking \ force=ma+mgSin\theta-350[/tex]

On substituting all the values, we get

⇒                           [tex]=1600(0.75+1600\times 9.81 Sin(2.3^{\circ})-350[/tex]

TMI Systems, a company that customizes software for construction cost estimates, repaid a loan obtained 5 years ago at 10% per year simple interest. If the amount that TMI repaid was $140,000, calculate the principal of the loan

Answers

The principal of the loan that TMI Systems repaid was $90,000.

The formula to calculate the principal of a loan is P = L + I, where P is the principal, L is the loan amount, and I is the total interest paid over the duration of the loan.

In this case, we are given that the loan amount was 10% per year simple interest, which can be calculated by multiplying the principal by the interest rate (0.1) and the duration of the loan (5 years). Therefore, the total interest paid over the duration of the loan is P x 0.1 x 5 = $50,000.

We are also given the total amount repaid, which is the sum of the principal and the total interest paid. Therefore, we can calculate the principal by subtracting the total interest paid from the total amount repaid.

This gives us $140,000 - $50,000 = $90,000. As the principal must be a positive value, the principal of the loan is $90,000.

Answers

The function that causes values of both x and to develop the highest feasible moment at A according to the provided suspended mass is written as 14715 Nm (clockwise).

What is mass ?

The quantity of matter or substance that makes up a thing is known as its mass. The unit of measurement is the kilogramme, abbreviated as kg. It's crucial to keep in mind that mass differs from weight. While weight varies with changes in gravity, mass never changes.

We have identified the following values,

adjust for any angle 00 ≤ θ ≤ 900 any extension 0 ≤ x ≤ 5 m.

So,

Let us consider an equation to calculate the moment using θ and x as variables around point A.

⇒ ((9−1.5) + x) (cosθ) (120) (9.81)

When we are simplifying the given equation gives us:

⇒ MA ​= (7.5+x) 1177.2 cosθ

Here the maximum moment will develop if θ = 0 and x=5 m.

Then, by substituting these values gives us:

⇒ MA​=(7.5+x)1177.2cosθ

⇒ MA​=(7.5+5)1177.2cos00

Thus, the value of MA is written as, 14715 Nm (clockwise)

A portable x-ray unit has a transformer, the 120V input of which is transformed to the 100kV output needed by the x-ray tube. The primary has 50 loops and draws a current of 10A when in use. What is ratio of the number of loops in the secondary to the number of loops in the primary

Answers

Answer:

2500 : 3

Explanation:

To solve this, let's build some relationships among the power, voltage, current and number of loops in an ideal transformer.

For an ideal transformer, the powers generated by the primary and secondary coils are the same. In other words, the input power and output power remain the same.

Input power = Output power

Where;

Input power = [tex]V_{p}[/tex] x [tex]I_p[/tex]

Output power = [tex]V_{s}[/tex] x [tex]I_s[/tex]

=> [tex]V_{p}[/tex] x [tex]I_p[/tex] = [tex]V_{s}[/tex] x [tex]I_s[/tex]

This can be re-written as:

[tex]\frac{V_p}{V_s}[/tex] = [tex]\frac{I_s}{I_p}[/tex]             ------------------(i)

Also, the transformer turns ratio (r) is the quotient of the number of turns/loops in the primary coil and the number of turns/loops in the secondary coil. i.e

r = [tex]\frac{N_p}{N_s}[/tex]

This ratio is equal to the ratio given in equation (i) i.e

r = [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex] = [tex]\frac{I_s}{I_p}[/tex]

=> r = [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex]

=> [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex]

This can be re-written as

=> [tex]\frac{N_s}{N_p}[/tex] = [tex]\frac{V_s}{V_p}[/tex]       -----------(ii)

From the question,

[tex]V_{p}[/tex] = 120V

[tex]V_{s}[/tex] = 100kV = 100000V

Substitute these values into equation (ii) as follows;

[tex]\frac{N_s}{N_p}[/tex] = [tex]\frac{100000}{120}[/tex]

[tex]\frac{N_s}{N_p}[/tex] =  [tex]\frac{10000}{12}[/tex]

[tex]\frac{N_s}{N_p}[/tex] =  [tex]\frac{2500}{3}[/tex]

Therefore, the ratio of the number of loops in the secondary to the number of loops in the primary is 2500 : 3

Answers

The shear plane angle is calculated as 49.4 degrees while the shear strain is given as 1.17

What is Shear Strain

Shear strain is a measure of deformation resulting from an applied force that is parallel to the surface of an object. It is usually expressed as a fractional change in the length of the object. Shear strain is a measure of the displacement of the surface points of an object in the direction perpendicular to the direction of the applied force.

The shear plane angle is the angle between the plane of shear stress and the normal to the plane of shear. It is typically measured in degrees and can range from 0 to 90 degrees.

(a) Shear plane angle = tan⁻¹((0.65-0.30)/0.30) = 49.4°

[tex]\frac{1}{R_T}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+\frac{1}{R_4}\\\\But\ R_1=R_2=R_3=R_4=8\ ohm\\\\\frac{1}{R_T} =\frac{1}{8} +\frac{1}{8} +\frac{1}{8} +\frac{1}{8} \\\\\frac{1}{R_T} =\frac{1+1+1+1}{8} \\\\\frac{1}{R_T} =\frac{4}{8} \\\\R_T=\frac{8}{4} \\\\R_T=2\ ohm[/tex]

The current flowing through the amplifier (I) is:

I = V / [tex]R_T[/tex] = 15 / 2 = 7.5 A

The audio power (P) when outputting this maximum voltage is given by:

P = V² / [tex]R_T[/tex] = I²[tex]R_T[/tex]. Therefore:

P = V² / [tex]R_T[/tex] = 15² / [tex]R_T[/tex] = 112.5 watts

So i have a Question so if you have somebody in your family and you dont share nothing with that person what do that person feel like so if they dont do nothing how would you feel.

The procedure is as follows in C++: double base calcPyramidVolume. Length, two bases. Double pyramid, width, Height.

The parameter variable for the following function prototype has a data type of double. Using the C double data type, high-precision floating-point data or integers are saved (up to 15 to 17 digits). There are large decimal number values recorded. In comparison to float data, values data may store twice as much information. As a result, it is referred to as a double data type. The double data type of the C programming language is used to store high-precision floating-point data or integers in computer memory. The double data type is so named because it can hold data that is twice as large as the float data type. Eight bytes, or 64 bits, make up a double.
