When installing subfloor plywood or OSB panels, the dimension of the panel needs to run perpendicular to the floor joist framing is the "Longer Dimension".

Oriented strand board (OSB) is a type of engineered wood that is similar to particle board in that it is made by applying adhesives and then compressing layers of wood strands in certain orientations. Armin Elmendorf created it in California in 1963.

Historically, the main advantage of OSB has been its lower production cost. It is rated comparable to plywood for most applications such as subflooring and wall sheathing. However, its effectiveness in damp regions is uncertain, as it is prone to retaining moisture, which can cause the board's edges to swell.

Answer:

Induced draft is a mechanical draft created by air pulled through the boiler firebox by a blower located in the breaching after the boiler.

Explanation:

A light weight vehicle traveling 50 mph can stop in approximately 200 feet.

The break system of a car is composed by several items that are always working together to slow down and bring a vehicle to a complete stop. It also has the function of keeping the car stationary when it is parked. In general, this system has two manual activation modes: the lever and the pedal, with the exception of vehicles adapted for people with disabilities.

Most vehicles today use the disc brake system. Disc brakes work by using pads, which are held inside a hydraulic caliper, receiving pressure to brake. Such pads generate friction on a disc, which makes the vehicle stop permanently.

The drum brake is another type, being older and dependent on the famous linings to cause friction in the wheel and stop the vehicle. A hydraulic cylinder makes the plies move inside the drum, which is a hollow part fastened with screws and attached to the wheels. This type of brake is on the rear wheels, for the most common models.

(a) The height of the cliff is 80.5 m

(b) The final velocity of the stone before it strikes A is 26.22 m/s

(c) The maximum height reached by the stone is 88.67 m

Velocity may be defined as the rate at which an object moves in a certain direction. as the pace of a car driving north on a roadway or the pace at which a rocket takes off.

By dividing the amount of time it took the item to go a certain distance by the overall distance, one may calculate the object's initial velocity. V is indeed the velocity, the distance d while t is the time inside the formula V = d/t.

(a) Using the same coordinate system assumed in Eq. , we solve for y=h:

h=y₀+v₀sinθ₀t−1/2gt²

which yields h=80.5m for y₀=0, v₀=46.0m/s, θ₀=65.0°, and t=5.54s.

(b) The horizontal motion is steady, sovₓ =v₀ₓ =v₀cosθ₀ but the vertical component of velocity varies according to Eq. . Thus, the speed at impact is

v=√(v₀ cos₀)²+(v₀ sinθ₀− gt)²=26.22m/s

Explanation:

Los seres humanos siempre han tenido la necesidad de explicar y comprender los hechos sobre el mundo, ellos mismos y la naturaleza. La religión se configura como un conjunto de creencias comunes a una comunidad, que busca conectar al hombre con una fe en una divinidad superior que explique una visión y construcción del mundo. En sentido antropológico, la religión es una construcción evolutiva de parámetros sociales y dogmáticos como búsqueda de la creación de un sentido de pertenencia social, además de la búsqueda de la comprensión de uno mismo y del desarrollo espiritual.

La biología y la filosofía surgen como conceptos amplios que buscan explicar otros conceptos sobre la ciencia de manera sistemática, diferente a buscar una comprensión del mundo a través de la religión. La filosofía como concepto de que el hombre puede comprender el mundo a través de sus propias visiones y descubrimientos, desarrollando el pensamiento crítico y la búsqueda del conocimiento, que desarrolló las ciencias, entre ellas la biología que ayudó en la comprensión de parámetros esenciales para la calidad de vida humana, como la medicina por ejemplo.

Entonces hay una convergencia de los conceptos de religión, biología y filosofía, y es posible que el hombre crea en cada uno sin que el otro concepto se vea afectado.

Given data:

Diameter of the copper cylindrical rod = 16 mm

Yield strength  = 250 MPa

Calculating the percent cold work

\($\text{Percentage Cold Work} = \frac{\pi\left(\frac{d_0}{2}\right)^2-\pi\left(\frac{d_d}{2}\right)^2}{\pi\left(\frac{d_0}{2}}\right)^2} \times 100$\)

                                  \($ = \frac{\pi\left(\frac{16}{2}\right)^2-\pi\left(\frac{11.3}{2}\right)^2}{\pi\left(\frac{16}{2}}\right)^2} \times 100$\)

                                  = 50% CW

Therefore, at \(50\% \ CW\), the yield strength of copper will be of the order of 330 MPa.

The ductility will be 4% elongation (EL).

Rather than performing drawing in single operation, we draw some of the fraction of total deformation, and then the anneal them to recrystallize and also finally w do cold work on the material  for the second time to achieve its final diameter, ductility and yield strength.

\(21\% \ CW\)is required for a yield strength of \(250 \ MPa\). Similarly, a maximum of \(23\% \ CW\) is required for\(12\% \ EL\).

The average of the two values is \(22\% \ CW\). To achieve both the \(\text{specified yield strength and ductility,}\) the copper should be deformed to\(22\% \ CW\). The\(\text{ final diameter}\) after the first drawing and the initial diameter for the second drawing is \($d_0'$\) , then

\($22\% \ CW = \frac{\pi\left(\frac{d_0'}{2}\right)^2-\pi\left(\frac{11.3}{2}\right)^2}{\pi\left(\frac{d_0'}{2}}\right)^2} \times 100$\)

\($d_0'=\frac{11.3}{\sqrt{1-\frac{22\% \ CW}{100}}}$\)

This question is incomplete, the complete question is;

For a steel alloy it has been determined that a carburizing heat treatment of 11.3 h duration at Temperature T1 will raise the carbon concentration to 0.44 wt% at a point 1.8 mm from the surface. A separate experiment is performed at T2 that doubles the diffusion coefficient for carbon in steel.

Estimate the time necessary to achieve the same concentration at a 4.9 mm position for an identical steel and at the same carburizing temperature T2.

Answer:

the required time to achieve the same concentration at a 4.9 is 83.733 hrs

Explanation:

Given the data in the question;

treatment time t₁ = 11.3 hours

Carbon concentration = 0.444 wt%

thickness at surface x₁ = 1.8 mm = 0.0018 m

thickness at identical steel x₂ = 4.9 mm = 0.0049 m

Now, Using Fick's second law inform of diffusion

\(x^2\) / Dt = constant

where D is constant

then

\(x^2\) / t = constant

\(x^2_1\) / t₁ = \(x^2_2\) / t₂

\(x^2_1\) t₂ = t₁\(x^2_2\)

t₂ = t₁\(x^2_2\) / \(x^2_1\)

t₂ = (\(x^2_2\) / \(x^2_1\))t₁

t₂ = \((\) \(x_2\) / \(x_1\) \()^2\) × t₁

so we substitute

t₂ = \((\) 0.0049  / 0.0018  \()^2\) × 11.3 hrs

t₂ = 7.41 × 11.3 hrs

t₂ = 83.733 hrs

Therefore, the required time to achieve the same concentration at a 4.9 is 83.733 hrs

Given:

kg (glass) = 0.78 W/m⋅K, ka (air) = 0.026 W/m⋅K, h1 = 10 W/m2⋅K, h2 = 25 W/m2⋅K, glass length = Lg = 3 mm = 0.003 m, Lo = 3 mm = 0.003 m, La = 12 mm = 0.012 Height = 1.5 m, width = 2.4 m, room temperature = T = 20°C. Therefore:

Total resistance per unit area is given as:

\(R"=\frac{1}{h_1}+\frac{L_g}{k_g}+\frac{L_a}{k_a} +\frac{L_o}{k_g}+\frac{1}{h_2} \\\\R"=\frac{1}{10}+\frac{0.003}{0.78}+\frac{0.012}{0.026} +\frac{0.003}{0.78}+\frac{1}{25} \\\\R"=0.1+0.00385+0.46154+0.00385+0.04\\\\R"=0.60924\ K.m^2/W\)

Area = A = height * width = 1.5 m × 2.4 m = 3.6 m²

The change in temperature = ΔT = 20 °C - (-5 °C) = 25 °C

The rate of heat loss is given as:

\(\dot {Q}=A*\frac{\Delta T}{R"}= 3.6*\frac{25}{0.60924}\\ \\\dot {Q}=147.73\ W\)

The inner surface temperature (Ti) is given as:

Technician A is correct in stating that tire pressure will drop 1 PSI for every 10 degrees drop in temperature. However, Technician B's statement that tire pressure will increase as the vehicle is being driven is not entirely accurate.

Technician A's statement regarding the relationship between tire pressure and temperature is accurate. As temperature decreases, the air inside the tire contracts, causing a drop in pressure. This phenomenon is known as the ideal gas law, which states that pressure and temperature are inversely proportional when the volume and amount of gas are constant.

Technician B's statement about tire pressure increasing as the vehicle is being driven is not entirely correct. While tire pressure can increase during driving due to factors like friction and heat generation, it is not a consistent or significant increase. The primary reason for any pressure increase during driving is the heat generated by the tire's contact with the road, which can cause a temporary rise in pressure. However, this increase is typically minimal and is not a continuous or significant change.

Overall, Technician A's statement about the relationship between tire pressure and temperature is accurate, while Technician B's statement about tire pressure increasing as the vehicle is being driven is not entirely correct.
