pet is a commonly used polymer for food and beverage containers. for a pet specimen that experiences cyclic loading with a mean stress of 25 mpa, what is the maximum cyclic tensile stress that the part can experience such that it survives at least 1 million cycles?

Answer:

From electrical energy to radiation

Explanation:

A light bulb converts electrical energy to light, which is nothing more than radiation. Don't regard radiation as a bad thing, this light is non-iodizing radiation, which does not have the possibility to alter our DNA, and thus it's safe.

The simplest example can be found in old lights (obsolete now because they are vastly inefficient). This lights were just resistors which turned electrical energy into heat. A very hot material reflects light in the form of radiation, as described above.

Technologies like LEDs are more complicated to explain.

There is no stress in the longitudinal direction since the pipe has no open ends.

What is longitudinal stress?

The tension that results from subjecting a pipe to internal pressure is known as longitudinal stress. A pipe's longitudinal stress acts in the direction of the pipe's length because it is parallel to the longitudinal axis of the pipe's centerline axis.

Tensile stress and compressive stress are two further subtypes of longitudinal stress. Tensile tension is the term for a type of stress that causes a body to grow longer.

Open ended pipe -longitudinal stress:

As we know if there are open ends there won't be any longitudinal stress

Hence, we can conclude that open pipes have no longitudinal stress

Explanation:

To derive the equation for the maximum angular speed of the output shaft, we need to know the input angular speed, gear ratio, and the maximum torque capacity of the system. The equation is as follows:

ω_out = (T_max / T_load) * (1 / i) * ω_in

Where ω_out is the maximum angular speed of the output shaft, T_max is the maximum torque capacity of the system, T_load is the load torque, i is the gear ratio, and ω_in is the input angular speed.

To calculate the misalignment angle, we need to know the distance between the input and output shafts and the amount of misalignment. The misalignment angle can be calculated using the following equation:

θ = tan⁻¹(d / r)

Where θ is the misalignment angle, d is the distance between the input and output shafts, and r is the radius of the shafts.


To derive the equation for the maximum angular speed of the output shaft and calculate the misalignment angle, we'll use the following terms:

1. Input shaft: The shaft that provides the initial rotational force.
2. Output shaft: The shaft that receives the rotational force from the input shaft and reaches the maximum angular speed.
3. Misalignment angle: The angle between the axes of the input and output shafts when they are not perfectly aligned.

The maximum angular speed (ω_max) of the output shaft can be found by considering the power transmitted through the shafts. Assuming there is no power loss, the power transmitted through the input and output shafts is equal:

P_in = P_out

Where P_in is the power of the input shaft, and P_out is the power of the output shaft.

The power of a rotating shaft is given by:

P = T * ω

Where T is the torque and ω is the angular speed.

Since there is no power loss, we can equate the input and output power:

T_in * ω_in = T_out * ω_max

To calculate the misalignment angle, we can use the geometry of the system (e.g., universal joints, gears, or couplings). The misalignment angle (θ) can be found by measuring the angle between the axes of the input and output shafts, typically using tools like a protractor or measuring software.

The maximum stress at the fixed end of a steel cantilever beam is 0.326 MPa with an uncertainty of 0.0033 MPa. This is determined by dividing the load (F) by the area of the beam, which is calculated by multiplying the length, width, and thickness of the beam.

The maximum stress at the fixed end of a steel cantilever beam is calculated by dividing the load (F) by the area of the beam. The load applied to the free end is 980 N with an uncertainty of 10 N. The beam is 100 mm long (l), 30 mm wide (w), and 10 mm thick (t). The area of the beam is calculated by multiplying the length by the width and thickness, which gives us 3000 mm2. Therefore, the maximum stress at the fixed end is 980 N / 3000 mm2 = 0.326 MPa. The uncertainty of the maximum stress can be calculated by taking the systematic error of 10 N divided by the area of the beam, which is 0.0033 MPa.

The Attendance at sports games decreased by 1,877 from 2011 to 2012, represented by the integer -1,877.

To numerically express the change in attendance, we can use an integer. In this case, attendance decreased by 1,877 from 2011 to 2012.

When attendance decreases, we use a negative integer to represent the change. The magnitude of the decrease is represented by the absolute value of the integer. In this scenario, attendance decreased by 1,877 individuals.

Since the attendance went from 45,015 in 2011 to 43,138 in 2012, we can calculate the change by subtracting the attendance in 2012 from the attendance in 2011. The result is -1,877, where the negative sign indicates a decrease.

Thus, the integer representing the attendance change from 2011 to 2012 is -1,877. This means that attendance decreased by 1,877 individuals during that period, resulting in a total attendance of 43,138 in 2012 when starting from 45,015 in 2011.

The number of possible schedules increases rapidly as the number of processes to be scheduled increases. For example, if we have four processes to be scheduled, there are 4! = 24 possible schedules.

There are several CPU scheduling algorithms available in computer science that determine the order of execution of processes scheduled on a processor. When given n processes to be scheduled on a single processor, the number of different schedules that can be created is calculated using the formula.



To understand this, let's consider a simple example where we have three processes to be scheduled: P1, P2, and P3. To calculate the number of possible schedules, we need to find the factorial of 3, which is: 3! = 3 x 2 x 1 = 6
Therefore, there are six possible schedules for three processes to be scheduled on a single processor. These schedules can be listed as follows: P1 P2 P3 P1 P3 P2 P2 P1 P3 P2 P3 P1 P3 P1 P2 P3 P2 P1.

The formula for the total number of possible schedules is given by n factorial, or n!Where n represents the number of processes to be scheduled on a single processor.

A CPU-scheduling algorithm determines an order for the execution of its scheduled processes. The CPU executes each process according to its order in the queue.

The CPU scheduler selects a process from the ready queue and dispatches it to the CPU for execution.The number of possible schedules for n processes on a single processor is calculated by the factorial function. The factorial function is a mathematical function that multiplies a number by all the positive integers less than it.

Mathematically, we can represent the factorial of n as n! and it can be computed as:n! = n * (n - 1) * (n - 2) * ... * 3 * 2 * 1

Therefore, the total number of possible schedules for n processes on a single processor is given by n factorial or n!.

i] To determine the density of the pellet, we can use the formula:

Density = Mass / Volume

Given that the mass of the pellet is 3.15 g and the volume is 3.22cm^{3}, we can calculate the density as follows:

Density = 3.15 g / 3.22 cm^{3}≈ 0.977 \(g/cm^{3\)

ii] The macropore volume in cm3/g can be calculated by dividing the macropore volume of the pellet (0.645 cm3) by the mass of the pellet (3.15 g):

Macropore volume = 0.645 cm^{3} / 3.15 g ≈ 0.205 \(cm^{3} /g\)

iii] The macropore void fraction in the pellet can be calculated using the formula:

Macropore void fraction = Macropore volume / Total volume of the pellet

Total volume of the pellet = Volume - Macropore volume = 3.22 cm^{3}- 0.645 cm^{3} = 2.575 cm^{3}

Macropore void fraction = 0.645 cm^{3} / 2.575 \(cm^{3}\)≈ 0.251 or 25.1%

iv] The micropore void fraction in the pellet can be calculated using the given micropore volume of the particles (0.40 cm^{3} /g) and the mass of the pellet (3.15 g):

Micropore volume in the pellet = Micropore volume/g x Mass

Micropore volume in the pellet = 0.40 \(cm^{3} /g\) x 3.15 g = 1.26 cm3

Micropore void fraction = Micropore volume in the pellet / Total volume of the pellet

Micropore void fraction = 1.26 \(cm^{3}\) / 2.575 \(cm^{3}\) ≈ 0.490 or 49.0%

v] The solid fraction of the pellet can be calculated by subtracting the sum of macropore and micropore void fractions from 1:

Solid fraction = 1 - (Macropore void fraction + Micropore void fraction)

Solid fraction = 1 - (0.251 + 0.490) ≈ 0.259 or 25.9%

vi] The density of the particles can be determined using the mass of the pellet (3.15 g) and the total volume of the particles:

Total volume of the particles = Volume - Macropore volume = 3.22 \(cm^{3}\)- 0.645 \(cm^{3}\) = 2.575\(cm^{3}\)

Density of the particles = Mass / Total volume of the particles

Density of the particles = 3.15 g / 2.575\(cm^{3}\) ≈ 1.222 \(g/cm^{3}\)
