which of the following would be a considered want than a rather need for most people

Answer:

a) The stress in the bar when F is 32,000 is approximately 7,100 psi

b) The load P that can be supported by the bar if the axial stress must not exceed is approximately 110,000 lb

Explanation:

The question topic relates to stresses in structures;

The given parameters of the steel bar are;

The width of the steel bar, W = 4.0 in.

The thickness of the steel bar, t = 1.125 in.

The formula for stress in a bar is given as follows;

\(Stress, \sigma = \dfrac{Force, F}{Area, A}\)

The cross sectional area of bar, A = W × t = 4.0 in. × 1.125 in. = 4.5 in.²

∴ The cross sectional area of bar, A = 4.5 in.²

a) The stress in the bar for F = 32,000 lb, is given as follows;

\(The \ stress \ in \ the \ bar , \sigma = \dfrac{ F}{A} = \dfrac{32,000 \ lb}{4.5 \ in.^2} = 7,111.\overline 1\)

The stress in the bar when F is 32,000 is σ = 7,111.\(\overline 1\) psi ≈ 7,100 psi

b) The load P that can be supported by the bar if the axial stress must not exceed, σ = 25,000 psi is given as follows;

\(\sigma = \dfrac{ P}{A}\)

Therefore;

P = σ × A = 25,000 psi × 4.5 in² = 112,500 lb

For the axial stress of 25,000 psi not to be exceeded, the maximum load that can be supported by the bar, P = 112,500 lb ≈ 110,000 lb.

Fast-moving particles assist in transferring thermal energy to a cup after hot tea is poured into by colliding with slow-moving particles.

Thermal energy is also referred to as heat and it can be defined as a form of energy that is transferred from one physical object to another, especially due to a difference in temperature.

During the process of heat conduction, thermal energy is primarily transferred between objects with different degrees of temperature and materials that are directly in contact with each other but differ in their ability to either accept or donate electrons.

Additionally, thermal energy is generally transferred from a hotter object (body) to a cooler one, provided that there is no external work done.

In conclusion, fast-moving particles assist in transferring thermal energy to a cup after hot tea is poured into by colliding with slow-moving particles.

What is Distance?

Distance is the sum of an object's movements, anyhow of direction. Distance can be defined as the quantum of space an object has covered, anyhow of its starting or ending position.

What is relegation?

The term" relegation" refers to a shift in an object's position. It's a vector volume with a magnitude and direction. The symbol for it's an arrow pointing from the original position to the ending place.

What is Velocity?

The primary index of an object's position and speed is its haste. It's the distance that an object peregrination in one unit of time. The relegation of the object in one unit of time is the description of haste.

What is average speed?

The overall distance the object covers in a given quantum of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.

To find the scale of your 3D model in relation to real life, you can use the following formula:

Scale = Real Life Size / Model Size

In your case, the real-life size of the bus shelter is given as 157 inches, and the model size is 14 inches. Plugging these values into the formula:

Scale = 157 inches / 14 inches

Scale ≈ 11.21

Therefore, the scale of your 3D model would be approximately 1:11.21. This means that one unit in your 3D model represents 11.21 units in real life. To convert any measurements from your 3D model to real-life measurements, you would multiply them by the scale factor.

Answer:

The outer tube of the pump is drawn with solid lines because it represents the visible edges of the object, which are the most important and prominent features of the drawing. Solid lines are used to indicate visible edges, while other types of lines such as dashed or dotted lines are used for hidden or construction lines that are not meant to be seen in the final drawing.

Explanation:

When drawing an object, it's important to distinguish between the visible edges and the hidden or construction lines. The visible edges are the lines that represent the outer contour or silhouette of the object, which define its shape and form. In the case of the bicycle pump, the outer tube is the most prominent and recognizable feature of the pump, so it's drawn with solid lines to emphasize its importance and to make it stand out from the other parts of the pump.

On the other hand, the hidden or construction lines are used to guide the drawing process, to show the internal structure or components of the object, or to indicate the position of other features that are not visible from the current viewpoint. These lines are usually drawn with dashed or dotted lines to distinguish them from the visible edges and to avoid confusion.

By using different types of lines, the artist can create a clear and accurate representation of the object, with all the relevant information conveyed in a concise and understandable way. This is especially important in technical or scientific drawings, where precision and clarity are essential for conveying complex ideas or designs.

Therefore, the information required is the volume of paint needed per unit area.

We can see here that the law of resistivity, also known as Ohm's law, states that the electrical resistance of a conductor is directly proportional to its resistivity and length, and inversely proportional to its cross-sectional area.

The Law of resistivity can be mathematically represented as:

R = ρ × (L / A)

Where:

R is the electrical resistance of the conductor,

ρ (rho) is the resistivity of the material,

L is the length of the conductor, and

A is the cross-sectional area of the conductor.

The resistivity (ρ) is a characteristic property of a material that quantifies its ability to resist the flow of electric current. It depends on the nature of the material, its temperature, and sometimes its purity. Resistivity is measured in ohm-meters (Ω·m).

Explanation:

A series RLC circuit containing a resistance of 12Ω, an inductive reactance of 47.13 Ω and a capacitive reactance of 31.83 Ω are connected in series across a 100V, 50Hz supply. Calculate the total circuit impedance, the circuits current, power factor

Given that:

R = 12 Ω, \(X_L=47.13\ ohm,\ X_C=31.83 \ ohm\), f = 50 Hz,  

A) Total circuit impedance (Z) is given by:

\(Z=\sqrt{R^2+(X_L-X_C)^2} =\sqrt{12^2+(47.13^2-31.83)^2} =\sqrt{378.09} =19.44\ ohm\)

B) the circuits current (I) is given by:

\(I=\frac{V}{Z}=\frac{100}{19.44}=5.14\ A\)

The voltage across the resistor (\(V_R\)) = IR= 5.14 × 12 = 61.68 V

The voltage across the inductor (\(V_L\)) = \(IX_L\) = 5.14 × 47.13 = 242.25 V

The voltage across the capacitor (\(V_c\)) = \(IX_C\) = 5.14 × 31.83 = 163.5 V

C) The power factor (Θ) is calculated as:

\(cos(\theta)=\frac{R}{Z}\\cos(\theta)=\frac{12}{19.44} =0.619\\\theta=cos^{-1}(0.6172)\\\theta=51.9^o\ laggin\)

Answer:

Explanation:

To find the width of the resulting fabric in centimeters, we need to first convert the width of a single strand from micrometers to centimeters.

1 micrometer (um) = 0.0001 cm.

So, the width of a single strand of fiber is:

19.2 um * 0.0001 cm/um = 0.00192 cm

If 1000 strands are adhered side by side, the width of the resulting fabric would be:

1000 * 0.00192 cm = 1.92 cm

So the width of the resulting fabric if 1000 strands are adhered side by side would be 1.92cm
