Based on a mechanical analysis, and the situation described, when carburetor hunts and surges at idle and top no load but runs well under load. the probable cause is an issue with the fuel delivery system.

The fuel delivery system in a car is a mechanical term that defines the storage of fuel in a fuel tank and the fuel pump draws fuel from the tank, thereby making the fuel travels through the fuel lines and is delivered through a fuel filter to the fuel injectors, such as carburetors.

In old vehicles, however, the fuel injectors are throttle.

Generally, it is believed that when carburetor hunts and surges at idle and top no load but runs well under load there is a problem with the fuel delivery system.

Critical load Fcr or buckling load is the value of load that causes the phenomenon of change from stable to unstable equilibrium state.

With that beign said, first it is neessary to calculate the moment of inercia about the x-axis:

\(Ix= \frac{db^3}{12}\\ Ix = \frac{2.(4)^3}{12} = 10.667in\)

Then it is necessary to calculate the moment of inercia about the y-axis:

\(Iy = \frac{db^3}{12}\\ Iy = \frac{4.(2)^3}{12} = 2.662in\)

Comparing both moments of inercia it is possible to assume that the minimun moment of inercia is the y-axis, so the minimun moment of inercia is 2662in.

And so, it is possible to calculate the critical load:

\(Pc\gamma = \frac{2046\pi ^2E.I}{L^2} \\Pc\gamma= \frac{2046.\pi ^2.(1,6.10^3.10^3).2662}{(10.12)^2} \\Pc\gamma= 5983,9db\)

Answer:

In Java:

import java.util.Scanner;

import java.lang.Math;

public class MyClass {

   public static void main(String args[]) {

     Scanner input = new Scanner(System.in);

     float x, y, z;

     System.out.print("Enter three numbers: ");

     x = input.nextFloat();      y = input.nextFloat();      z = input.nextFloat();

     System.out.print("Square root of x: ");

     System.out.printf("%.2f",Math.sqrt(x));

     System.out.println();

         fact*=i;

     }

     System.out.print("Factorial of z: "+fact);    

   }

}

Explanation:

This line declares x, y and z as float

     float x, y, z;

This line prompts user for three numbers

     System.out.print("Enter three numbers: ");

The next line get input for x, y and z

     x = input.nextFloat();      y = input.nextFloat();      z = input.nextFloat();

The italicized prints the square root of x rounded to 2 decimal places

     System.out.print("Square root of x: ");

     System.out.printf("%.2f",Math.sqrt(x));

     System.out.println();

The italicized prints the absolute of y - z to 2 decimal places      

     System.out.print("Absolute of y - z: ");

     System.out.printf("%.2f",Math.abs(y - z));

     System.out.println();

This initializes fact to 1

int fact = 1;

The following iteration calculates the factorial of ceil z

     for(int i = 1;i<=(int)Math.ceil(z);i++){

Answer:

a) The operation of a heat pump involves the extraction of energy in the form of heat Q₁ from a cold source

b) The modifications required to convert a plant operating on an ideal Carnot cycle to a plant operating on a Rankine cycle involves

i) Complete condensation of the vapor at the condenser to saturated liquid for pumping to the boiler

ii) Heating of the pumped, pressurized water to the boiler pressure

Explanation:

a) 1 - 2. Wet vapor enters compressor where it undergoes isentropic compression to state 2 by work W₁₂  

2 - 3. The vapor enters the condenser at state 2 where it undergoes isobaric and isothermal condensation to a liquid with the evolution of heat  Q₂

3 - 4. The condensed liquid is expanded isentropically with the work done equal to W₃₋₄

4 - 1. At the state 4, with reduced pressure from the previous expansion, the liquid makes its way to the evaporator where it absorbs heat, Q₁, from the body to be cooled.

b. i) Complete condensation of the vapor at the condenser to saturated liquid for pumping to the boiler

Here the condensation process is modified from partial condensation to complete condensation at the same temperature which reduces the size of the pump required to pump the liquid water as opposed to pumping steam plus liquid

ii) Heating of the pumped, pressurized water to the boiler pressure

The pumped water at state 4 will be required to be heated to saturated water temperature equivalent to the boiler pressure, hence heat will need to be added at state.

The statement, "Slope length is generally of greater significance in determining water erosion rate than is steepness of slope." is false.

In determining water erosion rate, the steepness of the slope is generally of greater significance than the slope length.

The steepness of a slope, also known as its gradient or slope angle, plays a crucial role in water erosion.

A steeper slope increases the velocity and energy of flowing water, leading to a higher potential for erosion.

As water flows down a steep slope, it gains more force and can carry more sediment, resulting in greater erosion.

While slope length can also influence water erosion to some extent, it is generally considered of lesser significance compared to slope steepness.

A longer slope provides a longer distance for water to flow and erode the soil, but if the slope is not steep, the velocity and erosive power of the water may be reduced.

Steeper slopes, even with shorter lengths, can accelerate the erosive effects of water.

Therefore, the steepness of the slope is generally more significant in determining water erosion rate than the slope length.

Answer:

1. 1111.5MPa

2. 56.1GPa

Explanation:

1. Longitudinal tensile stress can be obtained by obtaining the strength and volume of the fiber reinforcement. The derived formula is given by;

σcl = σm (1 - Vf) + σfVf

Substituting the figures, we will have;

45(1 - 0.30) + 3600(0.30)

45(0.70) + 1080

31.5 + 1080

= 1111.5MPa

2. Longitudinal modulus of elasticity or Young's modulus is the ability of an object to resist deformation. The derived formula is given by;

Ecl = EmVm + EfVf

Substituting the formula gives;

= 2.4 (1 - 0.30) + 131 (0.30)

= 2.4(0.70) + 39.3

= 16.8 + 39.3

= 56.1GPa

Using the appropriate relation, the longitudinal tensile stress and the longitudinal modulus are 1111.50 and 56.10 respectively.

Longitudinal tensile stress can be obtained using the relation :

Substituting the values into the relation:

45(1 - 0.30) + 3600(0.30)

45 × 0.70 + 1080

31.5 + 1080

= 1111.50 MPa

2.)

Longitudinal modulus of elasticity is obtained using the relation :

Substituting the values thus :

2.4 (1 - 0.30) + 131 (0.30)

= 2.4 × 0.70 + 39.3

= 16.8 + 39.3

= 56.10 GPa

Hence, the longitudinal tensile stress and the longitudinal modulus are 1111.50 and 56.10 respectively.

The velocity when the cable becomes taut can be obtained by assuming

that the tugboat collides with a barge moving in the same direction.

Response (approximate value):

Weight of the tugboat, m₁ = 240–ton

Speed of the tugboat, v₁ = 6 ft./s

Weight of the barge, m₂ = 100–ton

Rate at which the towing cable is being unwound, v₂ = 5.4 ft./s

Required:

Velocity of the tugboat after the cable becomes taut.

Solution:

m₁ = 240 ton = 240,000 kg

m₂ = 100 ton = 100,000 kg

The velocity of the barge at rest is assumed to be the rate at which the cable is being unwound, and in the direction of the tugboat.

According to the law of conservation of linear momentum, we have;

m₁ × v₁ + m₂ × v₂ = (m₁ + m₂) × v₃

Which gives;

240 × 6 + 100 × 5.4 = (240 + 100) × v₃

1980 = 340 × v₃

Which gives;

\(v_3 = \dfrac{1980}{340} = \dfrac{99}{17} = 5\frac{14}{17} \approx \mathbf{ 5.824}\)

Sodium hydroxide, NaOH, is a very useful compound in the chemical industry. Sodium hydroxide is used to make soap, detergent, paper, and many other products. It is also used to clean drains, dissolve grease, and other materials.

For commercial convenience, one form of sodium hydroxide that is sold commercially is the saturated solution. This solution is M, which is approximately by mass sodium hydroxide.

To prepare L of M solution, we must first find the number of moles of NaOH that will be required.

Then we will find the volume of the saturated solution that is required to make this solution.
To find the number of moles of NaOH that will be required, we will use the formula:

\(N = C x V\)Where, N = number of moles of NaOH, C = concentration of the solution, and V = volume of the solution.

In this case, C = M, which is the concentration of the solution that we want to make. And V = L, which is the volume of the solution that we want to make.

So,

\(N = M x LV = N / MC = 40% = 40 / 100 = 0.4 M\)

Volume of the saturated solution required to prepare the M solution:

\(V = N / MV = 4.69 L\)

We will require approximately \(4.69 L\)of the saturated solution to prepare L of M solution.
