The cars of a roller-coaster ride have a speed of 19.0 km/h as they pass over the top of the circular track. Neglect any friction and calculate their speed v when they reach the horizontal bottom position. At the top position, the radius of the circular path of their mass centers is 21 m, and all six cars have the same mass.V = -18 m What is v?X km/h

Answer:

\(v=23.6m/s\)

Explanation:

Velocity \(v_c=18.0km/h\)

Radius \(r=21m\)

initial velocity u\(u=19=>5.27778\)

Generally the equation for Angle is mathematically given by

\(\theta=\frac{v_c}{2r}\)

\(\theta=\frac{18}{2*21}\)

\(\theta=0.45\)

\(\theta=25.7831 \textdegree\)

Generally

Height of mass

\(h=\frac{rsin\theta}{\theta}\)

\(h=\frac{21sin25.78}{0.45}\)

\(h=20.3m\)

Generally the equation for Work Energy is mathematically given by

\(0.5mv_0^2+mgh=0.5mv^2\)

Therefore

\(v=\sqrt{u^2+2gh}\)

\(v=\sqrt{=5.27778^2+2*9.81*20.3}\)

\(v=23.6m/s\)

A net energy ratio (NER) of 0.2 implies that the energy resource in question requires a significant amount of energy to extract and produce, and that the energy output from the resource is relatively low.

This low NER suggests that the energy resource may not be a sustainable or efficient source of energy. Energy evaluators, who are responsible for assessing the viability and sustainability of energy resources, are likely to recommend against using this particular energy resource. This is because a low NER means that the energy resource is not efficient or cost-effective, and may not provide a significant energy output to meet energy demands.

Instead, energy evaluators may recommend investing in more sustainable and efficient energy resources, such as renewable energy sources like solar or wind power. These energy sources have higher NERs, meaning they provide a greater energy output relative to the energy input required for production. Additionally, renewable energy sources have a lower environmental impact compared to fossil fuels, which are often associated with high NERs.

In summary, a new energy resource with a net energy ratio of 0.2 is likely to be deemed inefficient and unsustainable by energy evaluators. As a result, investing in more sustainable and efficient energy resources, such as renewable energy sources, is recommended.

The molar volume of acetylene vapor at 247.1 K and 13.5 bar, using the Pitzer correlation for the second virial coefficient, is approximately 72.5 cm3/mol.

Explanation:

The Pitzer correlation can be used to estimate the second virial coefficient of a gas. The equation is given by B = (RTc)/(Pc) * (1 + m(1 - (T/Tc)^(0.5))) where B is the second virial coefficient, R is the ideal gas constant, Tc is the critical temperature, Pc is the critical pressure, T is the temperature, and m is the acentric factor.

Plugging in the given values and solving for B, we get B = -0.009413 m3/mol. Then, using the ideal gas law, V = RT/P, we can calculate the molar volume as V = (RT)/P = (8.314 J/mol-K * 247.1 K) / (13.5 bar * 10^5 Pa/bar) ≈ 0.0725 m3/mol ≈ 72.5 cm3/mol.

Answer:

  (x, y) = (5.76, 1 5/7)

Explanation:

The location of the centroid in the x-direction is the ratio of the first moment of area about the y-axis to the total area. Similarly, the y-coordinate of the centroid is the first moment of area about the x-axis, divided by the area.

For the moment about the y-axis, we can define a differential of area as ...

  dA = (y2 -y1)dx

where y2 = √(x/k2) and y1 = k1·x^3

The distance of that area from the y-axis is simply x.

So, the x-coordinate of the centroid is ...

  \(\displaystyle c_x=\frac{a_x}{a}=\frac{\int{x\cdot dA}}{\int{dA}}\\\\a_x=\int_0^{12}{x(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{5k_2^{1/2}}\cdot12^{5/2}-\frac{k_1}{5}12^5\\\\a=\int_0^{12}{(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{3k_2^{1/2}}\cdot12^{3/2}-\frac{k_1}{4}12^4\\\)

For k1 = 4/12^3 and k2=12/4^2, these evaluate to ...

  \(a_x=115.2\\a=20\\c_x=5.76\)

The y-coordinate of the centroid requires we find the distance of the differential of area from the x-axis. We can use (y2 +y1)/2 for that purpose. Then the y-coordinate is ...

  \(\displaystyle c_y=\frac{a_y}{a}\\\\a_y=\int_0^{12}{(\frac{y_2+y_1}{2}(y_2-y_1))}\,dx=\frac{1}{2}\int_0^{12}{(\frac{x}{k_2}-(k_1x^3)^2)}\,dx\\\\a_y=\frac{12^2}{4k_2}-\frac{k_1^212^7}{14}=\frac{240}{7}\\\\c_y=\frac{12}{7}\approx1.7143\)

The answer to this question as a percentage is 240%

Answer:

n

Explanation:

Answer:

First we determine the tensile strength using the equation;

Tₓ (MPa) = 3.45 × HB

{ Tₓ is tensile strength, HB is Brinell hardness = 225 }

therefore

Tₓ = 3.45 × 225

Tₓ = 775 Mpa

From Conclusions, It is stated that in order to achieve a tensile strength of 775 MPa for a steel, the percentage of the cold work should be 10

When the percentage of cold work for steel is up to 10,the ductility is 16% EL.

And 16% EL is greater than 12% EL

Therefore, it is possible to cold work steel to a given minimum Brinell hardness of 225 and at the same time a ductility of at least 12% EL

Answer:

"192.3 watt" is the right answer.

Explanation:

Given:

Efficient amplifier,

= 65%

or,

= 0.65

Power,

\(P_c=250 \ watt\)

As we know,

⇒ \(P_t=P_c(1+\frac{\mu^2}{2} )\)

By putting the values, we get

        \(=P_c(1+\frac{1}{2} )\)

        \(=1.5 \ P_c\)

Now,

⇒ \(P_i=(P_t-P_c)\)

        \(=1.5 \ P_c-P_c\)

        \(=\frac{P_c}{2}\)

DC input (0.65) will be equal to "\((\frac{P_c}{2} )\)".

hence,

The DC input power will be:

= \(\frac{250}{2}\times \frac{1}{0.65}\)

= \(\frac{125}{0.65}\)

= \(192.3 \ watt\)

Answer:

a) 764.45K

b) 210.48 kJ/kg

c) 30.14%

Explanation:

pressure ratio = 10

minimum temperature = 295 k

maximum temperature = 1240 k

isentropic efficiency for compressor = 83%

Isentropic efficiency for turbine = 87%

a) Air temperature at turbine exit

we can achieve this by interpolating for enthalpy

h4 = 783.05 kJ/kg ( calculated in the background ) at state 4 using Table A-17  for  Ideal gas properties of air

T4 ( temperature at Turbine exit ) = 760 + ( 780 - 760 ) \((\frac{783.05-778.18}{800.13-778.18} )\) = 764.45K

b) The net work output

first we determine the actual work input to compressor

Wc = h2 - h1  ( calculated values )

     = 626.57 - 295.17 =  331.4 kJ/kg

next determine the actual work done by Turbine

Wt = h3 - h4  ( calculated values )

     = 1324.93 - 783.05 = 541.88 kJ/kg

finally determine the network output of the cycle

Wnet = Wt - Wc

         = 541.88 - 331.4  = 210.48 kJ/kg

c) determine thermal efficiency

лth = Wnet / qin  ------ ( 1 )

where ; qin = h3 - h2

equation 1 becomes

лth = Wnet / ( h3 - h2 )

      = 210.48 / ( 1324.93 - 626.57 )

      = 0.3014  =  30.14%

The force reaction at support C is -24 kip (downward). Reactions at Support A: -13.5 kip (upward). Reactions at Support B: 27 kip (upward). Reactions at Support C: -24 kip (downward)

To determine the reactions at supports A, B, and C in the given structure, we need to analyze the equilibrium of forces and moments.

Given:

P = 13.5 kip (applied load)

EI is constant (flexural rigidity of the beam)

Force unit: kip (kips)

Distance unit: ft (feet)

Part A: Reactions at Support A

To find the force reaction at support A, we need to consider the equilibrium of forces and moments about point A. Since the beam is in equilibrium, the sum of vertical forces must be zero.

Sum of vertical forces = 0

RA + P = 0

RA = -P

Substituting the given value:

RA = -13.5 kip (upward)

Therefore, the force reaction at support A is -13.5 kip (upward).

Part B: Reactions at Support B

To find the force reaction at support B, we need to consider the equilibrium of forces and moments about point B.

Sum of vertical forces = 0

RA + RB - P = 0

RB = P - RA

RB = P - (-13.5)

RB = P + 13.5

Substituting the given value:

RB = 13.5 kip + 13.5 kip = 27 kip (upward)

Therefore, the force reaction at support B is 27 kip (upward).

Part C: Reactions at Support C

To find the force reaction at support C, we need to consider the equilibrium of forces and moments about point C.

Sum of vertical forces = 0

RB + RC - 3 (length of the beam in ft) = 0

RC = 3 - RB

Substituting the given value:

RC = 3 - 27 kip

RC = -24 kip (downward)

Therefore, the force reaction at support C is -24 kip (downward).

In summary:

Reactions at Support A: -13.5 kip (upward)

Reactions at Support B: 27 kip (upward)

Reactions at Support C: -24 kip (downward)
