Answer:

Beam of 25" depth and 12" width is sufficient.

I've attached a detailed section of the beam.

Explanation:

We are given;

Beam Span; L = 20 ft

Dead load; DL = 0.50 k/ft

Live load; LL = 0.65 k/ft.

Beam width; b = 12 inches

From ACI code, ultimate load is given as;

W_u = 1.2DL + 1.6LL

Thus;

W_u = 1.2(0.5) + 1.6(0.65)

W_u = 1.64 k/ft

Now, ultimate moment is given by the formula;

M_u = (W_u × L²)/8

M_u = (1.64 × 20²)/8

M_u = 82 k-ft

Since span is 20 ft, it's a bit larger than the average span beams, thus, let's try a depth of d = 25 inches.

Effective depth of a beam is given by the formula;

d_eff = d - clear cover - stirrup diameter - ½Main bar diameter

Now, let's adopt the following;

Clear cover = 1.5"

Stirrup diameter = 0.5"

Main bar diameter = 1"

Thus;

d_eff = 25" - 1.5" - 0.5" - ½(1")

d_eff = 22.5"

Now, let's find steel ratio(ρ) ;

ρ = Total A_s/(b × d_eff)

Now, A_s = ½ × area of main diameter bar

Thus, A_s = ½ × π × 1² = 0.785 in²

Let's use Nominal number of 3 bars as our main diameter bars.

Thus, total A_s = 3 × 0.785

Total A_s = 2.355 in²

Hence;

ρ = 2.355/(22.5 × 12)

ρ = 0.008722

Design moment Capacity is given;

M_n = Φ * ρ * Fy * b * d²[1 – (0.59ρfy/fc’)]/12

Φ is 0.9

f’c = 4,000 psi = 4 kpsi

fy = 60,000 psi = 60 kpsi

M_n = 0.9 × 0.008722 × 60 × 12 × 22.5²[1 - (0.59 × 0.008722 × 60/4)]/12

M_n = 220.03 k-ft

Thus: M_n > M_u

Thus, the beam of 25" depth and 12" width is sufficient.

This is an example of the conduction of electricity through metal. Free moving electrons on the car will conduct a electric field when a voltage is applied to the car;  in this case the transmission line, and would flow through the metal to the door handle causing electrocution.

Explanation:

1 meter ≈ 3.281 ft.

so,

1 m² = 1m×1m ≈ 3.281 × 3.281 = 10.764961 ft²

now we have 22.3 ft² of skin.

that would be then

22.3/10.764961 = 2.071535605 ≈ 2.1 m² or even more rounded ≈ 2 m²

The time (in seconds) required for the transformation in this new steel to reach 75% completion will be 90sec.

What is steel?

Steel is an iron alloy with additional carbon to increase its durability and fracture resistance when compared to other kinds of iron. Many other elements may exist or be added. Corrosion and oxidation-resistant stainless steels typically require an additional 11% chromium. Steel is utilised in structures, infrastructure, tools, ships, trains, cars, machinery, electrical appliances, weaponry, and rockets due to its great tensile strength and inexpensive cost.

By aurami relationship,

fβ(t) = 1-e(-kt⁴)

so, 0.95 = 1-e(-4.46×10⁻⁴× t⁴)

-0.05= -e(-4.46×10⁻⁴× t⁴)

ln(0.05)= -4.46×10⁻⁴× t⁴

-2.9957= -4.46×10⁻⁴× t⁴

0.6716×10⁻⁴ = t⁴

t= 0.905×10sec

=9.05sec

Explanation:

The type of data affects the type of analysis that can be conducted. Nominal data is data that is grouped into categories and cannot be ranked or ordered. Therefore, it is limited in terms of analysis that can be conducted.

Ordinal data is data that can be ranked or ordered but the differences between the categories are not equal. Therefore, ordinal data can be analyzed using non-parametric tests. Interval data is data that has equal intervals between categories but does not have a true zero point.

This type of data can be analyzed using parametric tests such as t-tests and ANOVA. Ratio data is data that has equal intervals between categories and a true zero point. This type of data can be analyzed using parametric tests and statistical modeling techniques.

In summary, the limits of what can be done to analyze the data based on the type of data depend on the characteristics of each data type. Nominal data has the most limited analysis capabilities, followed by ordinal data which can only be analyzed using non-parametric tests.

Current Gain when amplifier is common base and common emitter = -201 A

The formula used = IB+IE+IC=0

Think of current gain as the difference between the input and output current. The input current and output current in a common collector are the base current (IB and IE, respectively).

You should be able to determine all of this by using the formula IB+IE+IC=0, which states that the sum of all currents must be zero. Recognize that IE is negative if all currents are assumed to be positive entering the transistor; hence, the actual value of current gain is -201; nevertheless, we often just use the absolute amount.

Answer: Therefore, the annual depreciation for each year using the double-declining-balance method is $228,000 for the first three years, $194,000 for the fourth year, and $0 for the fifth year. The book value at the end of each year is as follows: $422,000 at the end of year 1, $194,000 at the end of year 2, $228,000 at the end of year 3, $0 at the end of year 4, and $80,000 at the end of year 5.

Explanation:  To calculate the annual depreciation using the double-declining-balance method, we first need to calculate the depreciation rate, which is double the straight-line depreciation rate. The straight-line depreciation rate is calculated as follows:

Depreciation rate = (Cost - Salvage value) / Useful life

Depreciation rate = ($650,000 - $80,000) / 5 years = $114,000 per year

Double-declining-balance depreciation rate = 2 x straight-line depreciation rate = 2 x $114,000 = $228,000 per year

Using this depreciation rate, we can calculate the annual depreciation and book value at the end of each year as follows:

Year 1:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 = $422,000

Year 2:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $228,000 = $194,000

Year 3:

Depreciation = $194,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 = $228,000

Year 4:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 - $228,000 = $0

Year 5:

Depreciation = $0

Book value = Salvage value = $80,000

Explanation:

From the given information:

Let the weight of the mix in the air be = \(W_{ma}\)

Let the weight of the mix in water be = \(W_{mw}\); &

the bulk specific gravity be = \(G_m\)

SO;

\(W_{mw} = W_{ma} - v \delta _{w} --- (1)\)

Also;

\(G_m = \dfrac{W_{mw}}{v \delta_w} --- (2)\)

From (2), make\(v \delta_w\) the subject:

\(v \delta_w = \dfrac{W_{ma}}{G_m}\)

Now, equation (1) can be rewritten as:

\(W_{mw} = W_{ma} - \dfrac{W_{ma}}{G_m}\)

\(G_m = \dfrac{W_{ma}}{W_{ma} - W_{mw}}\)

The angle of attack of a wing directly controls the C) distribution of pressures acting on the wing.

When the angle of attack of a wing is increased, the air moving over the curved upper surface of the wing must travel a greater distance and faster than the air moving beneath the wing's flat lower surface. This creates an area of lower air pressure above the wing and an area of higher air pressure beneath the wing, resulting in lift. The greater the angle of attack, the greater the lift produced.

However, if the angle of attack is too great, the airflow over the wing may separate, causing a loss of lift and potentially leading to a stall. Therefore, proper control of the angle of attack is crucial for safe and efficient flight.
