what are some of the key characteristics of an embedded os?

Hazard Rate is an analysis of the difference between the frequency of an event in one group and the frequency of the same event in another group over time. a) R(1)=0.998 b) t=6 Months

Hazard Rate , \(h(t)=\frac{f(t)}{R(t)}\)

There is a linear hazard rate for a component for t years,

λ(t)=0.4

(a)

The reliability function  R(t)=1−F(t)

Now,

\(F(t)=\int\limits^t_0 {λ(t)} \, dt \\ =\int\limits^t_0 {0.4tdt} \, \\ =0.4\int\limits^t_0 {tdt} \, dt\\ =0.4*[\frac{t^{2} }{2}] \\\\ =0.2t^{2}\)

Therefore, the Reliability function is  \(R(t)=1-0.2t^{2}\)

Now, for the reliability for the 1st month,

t=1 month= \(\frac{1}{2} years\)

therefore, the probability of a component failure within the first month of its operation is,

\(R(1)=1-0.2( \frac{1}{12}) ^{2} \\ =1-0.00138\\ =0.998\)

R(1)=0.998

(b)

Given that there is reliability of 0.95. that is,

R(t)=0.95

\(1-0.2t^{2} =0.95\\ 0.2t^{2} =1-0.95\\ t^{2} =\frac{0.05}{0.2}\\t=\sqrt{2.5} \\ t=0.5 years\)

Thus, for a reliability of 0.95, the design of life requires almost 6 months.

Answer:

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

Explanation:

From Heat Transfer we determine that heat transfer rate due to electromagnetic radiation (\(\dot Q\)), measured in BTU per hour, is represented by this formula:

\(\dot Q = \epsilon\cdot A\cdot \sigma \cdot (T_{s}^{4}-T_{b}^{4})\) (1)

Where:

\(\epsilon\) - Emissivity, dimensionless.

\(A\) - Surface area of the student, measured in square feet.

\(\sigma\) - Stefan-Boltzmann constant, measured in BTU per hour-square feet-quartic Rankine.

\(T_{s}\) - Temperature of the student, measured in Rankine.

\(T_{b}\) - Temperature of the bus, measured in Rankine.

If we know that \(\epsilon = 0.90\), \(A = 16.188\,ft^{2}\), \(\sigma = 1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}}\), \(T_{s} = 554.07\,R\) and \(T_{b} = 527.67\,R\), then the heat transfer rate due to electromagnetic radiation is:

\(\dot Q = (0.90)\cdot (16.188\,ft^{2})\cdot \left(1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}} \right)\cdot [(554.07\,R)^{4}-(527.67\,R)^{4}]\)

\(\dot Q = 417.492\,\frac{BTU}{h}\)

Under the consideration of steady heat transfer we find that the net energy transfer from the student's body during the 20 min-ride to school is:

\(Q = \dot Q \cdot \Delta t\) (2)

Where \(\Delta t\) is the heat transfer time, measured in hours.

If we know that \(\dot Q = 417.492\,\frac{BTU}{h}\) and \(\Delta t = \frac{1}{3}\,h\), then the net energy transfer is:

\(Q = \left(417.492\,\frac{BTU}{h} \right)\cdot \left(\frac{1}{3}\,h \right)\)

\(Q = 139.164\,BTU\)

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

When an ordinarily elastic material cracks brittlely, there is little or no outward trace of material deformation prior to failure.

The plastic deformation that occurs before failure is minimal or nonexistent in brittle fractures. Glasses, ceramics, as well as various polymers and metals, frequently fracture in a brittle way.

When a material is exposed to forces below its yield limit, brittle fractures take place. A ductile material is typically the foundation for machine design, and the design criteria are intended to prevent plastic and, in some circumstances, elastic deformations.

Material that has undergone either no plastic deformation or very little plastic deformation prior to fracture is said to have fractured with brittleness. Since they all share this quality, brittle materials include rock, concrete, glass, and cast iron.

Answer:

Most cylinder wear occurs at the top of ring travel.

Answer:

\(\triangle h=4.935m\)

Explanation:

From the question we are told that:

Liquid density \(\rho=800\)

Diameter of pipe \(d=4cm \approx 0.004m\)

Diameter of venture \(d=10cm \approx 0.010m\)

Specific weight of mercury P_mg \(133 kN/m^3\)

Flow rate \(r=0.05 m^3/s\)

Area A:

            \(A_1=\frac{\pi}{4}0.1^2\\A_1=0.00785m^2\\A_2=\frac{\pi}{4}0.04^2\\A_2=0.001256m^2\\\)

Generally the Bernoulli's equation is mathematically given by

\(\frac{P_1}{\rho_1g}+\frac{V_1^2}{2g}=\frac{P_2}{\rho g}+\frac{V_2^2}{2g}\\\)

Where

\(V_1=\frac{r}{A_1} \\\\ &V_1=\frac{r}{A_2}\)

Therefore

\(P_1-P_2=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)

Generally the equation for pressure difference b/w manometer fluid is given as

\(P_1-P_2=(p_mg-pg)\triangle h\)

Therefore

\((p_mg-pg)\triangle h=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)

\(\triangle h=\frac{\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})}{(p_mg-pg)}\)

\(\triangle h=\frac{\frac{(800)(0.05)^2}{2}(\frac{(0.1)^2-(0.4)^2}{(0.1)^2(0.04)^2})}{(1.33*10^3-800*9.81)}\)

\(\triangle h=4.935m\)

To express in numerical terms how hot or cold something is, the idea of temperature is used. Using a thermometer, one can gauge temperature. Different temperature scales, which historically relied on various reference points and thermometric materials for definition, are used to calibrate thermometers. The most popular scales are the Kelvin scale (K), which is mostly used for scientific reasons, the Fahrenheit scale (°F), and the Celsius scale, with the unit symbol °C (formerly known as centigrade). One of the International System of Units' seven base units is the kelvin (SI). The lowest temperature on the thermodynamic scale is absolute zero, or 0 kelvin, or 273.15 degrees Celsius. The third law of thermodynamics acknowledges that it can be experimentally approached extremely closely but never actually reached. At that temperature, it would be difficult to extract energy from a body in the form of heat. All branches of natural science, including physics, chemistry, Earth science, astronomy, biology, ecology, material science, metallurgy, mechanical engineering, and geography, as well as the majority of facets of daily living, depend on temperature.

Explanation:

To determine the water level (h) at which vapor cavities begin to form at the throat of the nozzle, we need to consider the conditions under which cavitation occurs. Cavitation takes place when the local pressure in a fluid falls below its vapor pressure, causing the liquid to vaporize.

In Fig. P3.133, the fluid flows through a converging nozzle, where the flow velocity increases, and the pressure decreases according to Bernoulli's equation:

P1 + 0.5ρV1² + ρgh = P2 + 0.5ρV2² + ρgh2

Since we are looking for the water level (h) where vapor cavities form at the throat of the nozzle, we can assume that the pressure at this point (P2) is equal to the vapor pressure of water (Pv). Also, let's assume that h1 = h and h2 = 0. The Bernoulli's equation can be simplified to:

P1 + ρgh = Pv + 0.5ρV2²

We are given that losses are neglected in the problem. Therefore, we can apply the continuity equation, which relates the velocity and the cross-sectional area of the fluid at different points along the nozzle:

A1V1 = A2V2

Now, we can solve for V2 in terms of V1 and the areas (A1 and A2) and substitute it into the Bernoulli's equation. After rearranging and solving for h, we obtain:

h = (Pv - P1) / ρg + 0.5(V1²)((A2/A1)² - 1) / g

By calculating the water level (h) using the given parameters and the above equation, we can determine at what height vapor cavities begin to form at the throat of the nozzle

In the Resource Conservation and Recovery Act (RCRA), generators, transporters, and Treatment, Storage, and Disposal Facilities (TSDFs) of hazardous waste are each required to comply with the hazardous waste manifest system. The specific provisions outlining these requirements can be found in different sections of RCRA.

Generators: The requirements for generators to comply with the hazardous waste manifest system are outlined in 40 CFR Part 262, specifically Subpart B - Pre-Transport Requirements. This section of RCRA details the responsibilities of generators in properly identifying, documenting, and packaging hazardous waste for transportation. Generators are required to prepare a manifest (EPA Form 8700-22) for each shipment of hazardous waste and provide copies of the manifest to the transporter and the designated TSDF.

Transporters: The requirements for transporters to comply with the hazardous waste manifest system can be found in 40 CFR Part 263, specifically Subpart C - Manifest System, and Subpart E - Transportation. These sections of RCRA outline the obligations of transporters in handling, transporting, and delivering hazardous waste. Transporters are responsible for ensuring that they have a properly completed manifest for each shipment of hazardous waste they transport, and they must sign the manifest to acknowledge receipt of the waste from the generator and provide a copy of the signed manifest to the designated TSDF.

TSDF Facilities: The requirements for TSDF facilities to comply with the hazardous waste manifest system are covered in 40 CFR Part 264 (for hazardous waste treatment, storage, and disposal facilities) and Part 265 (for interim status facilities). These sections of RCRA specify the obligations of TSDFs in receiving, managing, and documenting the hazardous waste they receive. TSDFs are required to sign the manifest upon receipt of the waste, verify the information, and keep a copy of the manifest as part of their records.

It's important to note that these are general references to the relevant sections of RCRA where the requirements for compliance with the hazardous waste manifest system can be found. The actual details and specific provisions may be subject to further interpretation and regulatory updates.

1.)Strain 2) Stress 3) elasticity 4)Toughness 5)Polymer.

The ability of a body to withstand a force that causes distortion and to regain its normal size and shape once the force has been withdrawn is known as elasticity. Solid objects will deform when sufficient loads are placed on them; if the material is elastic, the object will return to its original size and shape after the weights have been removed. Contrastingly, in the case of plasticity, the object is unable to do so and instead maintains its deformed state.

For various materials, the underlying physical causes of elastic behavior might differ significantly. When forces are applied to metals, the atomic lattice undergoes size and form changes (energy is added to the system). The lattice returns to its initial lower energy state after the application of forces.
