The permeability of different concrete designs varies. Permeable concrete is a type of concrete that is porous and allows water to pass through it. We recently used this on a project where traffic was driving over an area with drainage issues.

What exactly is porosity, and how does it relate to concrete permeability?

The volume of voids in concrete is measured by porosity. The rate of moisture flow through concrete under a pressure gradient is defined as permeability.

Moisture must be able to move through voids that are interconnected and of a certain size. Moisture flow is slowed by discontinuous pores and pores with narrow entrances. Permeability is low in a mature, well-cured, well-proportioned paste (low w/cm), even if porosity is high. Permeability is increased in porous concrete.

According to the question of tensile stress, 5.66 kips is required to stretch them the required amount and 0.0015 in deflection is require.

What is tensile stress?
Tensile stress is a physical force exerted on a material in opposing directions along its length. It is a measure of the amount of force necessary to pull a material apart, or to cause a fracture. Tensile stress occurs when a material is placed under load and the load is applied in a way that causes the material to elongate. When a material is subjected to tensile stress, the molecules of the material become stretched and the material's shape is changed.

The required force is calculated by multiplying the area of the rod by the desired stress:

F = A * σ = π/4 * (0.75 in)^2 * 30 ksi = 5.66 kips

The required deflection is determined by multiplying the required force by the length of the rod and then dividing by the modulus of elasticity (E) and the area of the rod:

δ = FL/EA = 5.66 kips * 30 ft / (30,000 ksi * π/4 * (0.75 in)2) = 0.0015 in

Therefore, the required force is 5.66 kips and the required deflection is 0.0015 in.

The influence of an ion's nucleus on its electron cloud extends outward to a distance called the ionic radius.

When an atom loses or gains an electron, an ion is created. A cation is formed when an atom loses an electron, and an anion is formed when an atom gains an electron. The ionic radius is the furthest point away from the ion's nucleus that its outermost shell can extend.

A cation's atomic size will be lower than that of its parent atom. Compared to its parent atom, an anion is comparatively large. That's because the net effective nuclear charge gets drowned out by the repulsion between electrons caused by an atom gaining electrons.

Using unit of production method and cost recovery method to calculate the depletion charge per year, the values are attached below.

Depletion charge is a non-cash expense on an income statement that is used to allocate the cost of a natural resource, such as timber or minerals, over its estimated useful life. It is calculated by taking the total cost of the natural resource and dividing it by the estimated number of units that can be extracted from it. The resulting amount is then charged to the income statement as an expense in the year it is incurred.

(a)

a) Using the Units of Production Method:

Year 1: Depletion Charge = (2.5 million tons x $30) x 5% = $37,500

Year 2: Depletion Charge = (2 million tons x $25) x 5% = $25,000

Year 3: Depletion Charge = (1.5 million tons x $35) x 5% = $26,250

Year 4: Depletion Charge = (1 million tons x $35) x 5% = $17,500

Year 5: Depletion Charge = (0.5 million tons x $40) x 5% = $10,000

Total Depletion Charge = $106,250

b) Using the Cost Recovery Method:

Year 1: Depletion Charge = ($1.5 million x 50%) x (60,000/2.5 million) = $18000

Year 2: Depletion Charge = ($1.5 million x 50%) x (50,000/2.5 million) = $15000

The statements below that refer to the design and operation of the power sub-system on a spacecraft is option

      7. For a spacecraft in planetary orbit, power for the eclipse period is commonly provided by a battery as a secondary power source, and an increased solar array area to give extra power to charge the batteries whilst not in eclipse.

Radioisotope Thermoelectric Generators (RTGS) are commonly applied to earth-orbiting spacecraft to provide power for the eclipse period when the solar panels are ineffective.

This is because RTGS use the heat generated by the decay of a radioactive material to generate electricity, which allows them to continue to produce power even when the solar panels are not receiving sunlight.

Therefore, Jupiter is considered the approximate limit for solar-powered orbital missions; missions to planets beyond this will require Radioisotope Thermoelectric Generators (RTGS). This is because as you move farther away from the sun, the amount of sunlight received by the solar panels decreases, making it difficult to generate enough power to operate the spacecraft. RTGS are a more reliable power source for missions to these outer planets because they do not rely on sunlight to generate power.

The velocity of the cylinder when it moves downward s = 0.2m from its equilibrium position is; 1.55 m/s

At the equilibrium position, since;

F_sp = kx₀

We are given kAB = 120. Thus;

F_sp = 120x₀

Resolving forces about the y-axis gives;

∑f_y = 0, we have;

120x₀  - 4(9.81) = 0

x₀ = (6 * 9.81)/120

x₀ = 0.4905 m

Thus, when the 60 N force is applied, the compression of the spring is;

x = s + 0.4905 m

Thus;

F_sp = 120(s + 0.4905 m)

Then balancing of upward and downward forces gives us;

120(s + 0.4905) − 60 − 6(9.81) = 6(−a)

120s - 60 = -6a

a = 10 - 20s

At the initial condition v=0 at s = 0, we integrate to get the velocity;

v²/2 = 10s - 20s²

v = √(20s - 40s²)

At s = 0.2 m, we have;

The size of the THHN feeder conductor required for two 230 VAC, 7.5 HP motors, one 115 VAC, 1.5 HP short time motor and one 230 VAC, 0.75 HP motor is 3 AWG.

To calculate the size of the THHN feeder conductor, we first need to calculate the total load current for all the motors. To do that, we will use the following formula: I = (HP x 745.7) / (V x 1.73).

For the two 7.5 HP motors, the total load current is (7.5 x 745.7) / (230 x 1.73) = 29.7 A. For the 1.5 HP short-time motor, the total load current is (1.5 x 745.7) / (115 x 1.73) = 8.85 A. For the 0.75 HP motor, the total load current is (0.75 x 745.7) / (230 x 1.73) = 4.41 A.

Adding all the load currents yields a total load current of 42.96 A. Then we can refer to the NEC Table 310.15(B)(16) to determine the minimum THHN feeder conductor size. At 42.96 A, the minimum THHN feeder conductor size is 3 AW.

The wind force on the screen is approximately 5,341.5936 [tex]lb_f[/tex]

Explanation:

The speed of the wind, v = 36 mph

The width of the outdoor movie, w = 70 ft. wide

The height of the outdoor movie, h = 20 ft. tall

The drag coefficient, Cd = 1.15

We have;

[tex]C_d = \dfrac{F}{\dfrac{\rho \cdot v^2 \cdot A}{2} }[/tex]

From which we have;

The wind force, F = 0.00256·[tex]C_d[/tex]·v²·A

Where;

A = The cross sectional area of the rectangular outdoor movie screen, A = w × h

∴ A = 70 ft. × 20 ft. = 1,400 ft.²

The wind force, F = 0.00256 × 1.15 × (36 mph)² × 1,400 ft.² = 5,341.5936 [tex]lb_f[/tex]

The wind force on the screen, F = 5,341.5936 [tex]lb_f[/tex].

The wind force on the outdoor movie screen is;

F = 23437.26 N

We are given;

Wind speed; v = 36 mph = 16.0934 m/s

Width of screen; w = 70 ft = 21.336 m

Height of screen; h = 20 ft = 6.096 m

Drag coefficient; Cd = 1.15

Now formula for the drag force is;

F = ½•C_d•ρ•A•v²

Where;

F is drag force

C_d is drag coefficient

ρ is density of object

v is speed of object

A is area

Let us use density as 1.21 kg/m³

Area; A = wh = (21.336 × 6.096)

Thus;

F = ½ × 1.15 × 1.21 × (21.336 × 6.096) × 16.0934²
