Answer:

1.) 103.23 degree centigrade

2.) 126.96 degree centigrade

Explanation:

Given that a transparent film is to be bonded onto the top surface of a solid plate inside a heated chamber. For the bond to cure properly, a temperature of 70°C is to be maintained at the bond, between the film and the solid plate. The transparent film has a thickness of 1 mm and thermal conductivity of 0.05 W/m·K, while the solid plate is 13 mm thick and has a thermal conductivity of 1.2 W/m·K. Inside the heated chamber, the convection heat transfer coefficient is 70 W/m2·K. If the bottom surface of the solid plate is maintained at 52°C.

To determine the temperature inside the heated Chamber, let us first calculate the heat transfer rate per unit area through the plate by using the formula

Heat transfer rate R = k( Tb - T2)/L

Where

k = 1.2 W/mA.K

Tb = 70 degree

T2 = 52 degree

L = 13mm = 13/1000 = 0.013m

substitute all the parameters into the formula above.

R = 1.2 x ( 70 - 52 )/ 0.013

R = 1.2 x (18/0.013)

R = 1661. 5 W/m^2

the surface temperature of the transparent film will be

Ts = Tb + (RLf/Kf)

Ts = 70 + (1661.5 x 0.001)/0.05

Ts = 70 + (1.6615)/0.05

Ts = 70 + 33.23

Ts = 103.23 degree centigrade

the temperature inside the heated Chamber will be calculated by using the formula

Ti = Ts + (R/h)

Ti = 103.23 + (1661.5/70)

Ti = 103.23 + 23.74

Ti = 126.97 degree centigrade

In computer science, the recurrence relation is used to calculate the time complexity of a recursive function. Here, we are to write a recurrence relation for the running time of the recursive version of Insertion sort.

Insertion sort can be expressed as a recursive procedure as follows:In order to sort A[1…n], we recursively sort A[1…n−1] and then insert A[n] into the sorted array A[n−1].Algorithm to insert A[n] into the sorted array A[1..n-1]:1. Recursive call to sort A[1..n-1].2. Put the last element in the correct position by shifting the array. Let's denote the time taken by the function as T(n).The worst-case scenario happens when the input array is sorted in decreasing order. In this case, each time we enter the loop and slide an element to the right, we must compare it to each element in the sorted sub-array. Therefore, the time complexity of the insertion sort algorithm in the worst-case is O(n2). The recurrence relation for the running time of the recursive version of insertion sort is given by:T(n) = T(n-1) + nwhere n is the input size, T(n-1) represents the time taken by the function to sort n-1 elements, and n is the time taken to sort n elements.The base case for this recurrence is when there is only one element, i.e., T(1) = 1.The time complexity of insertion sort can be determined using the recurrence relation. So, T(n) is given by:T(n) = T(n-1) + n= T(n-2) + (n-1) + n= T(n-3) + (n-2) + (n-1) + n= ........= T(1) + 2 + 3 + ... + (n-1) + n= n(n+1)/2= O(n2)In conclusion, we can say that the time complexity of the recursive version of insertion sort is O(n2).

Vast majority of automotive engine are mostly of the piston type, and not the rotary type engine that has long gone obsolete. The piston type engine has a longer life when compared to the rotary engine, and emission is less. The emission from the rotary engine was exacerbated by the fact that the lubricant was added with the fuel directly into the engine, whereas the piston type engine has a and separate channel for fuel and lubricant.  

Technician A is correct. Technician B is also correct that a Digital Multimeter (DMM) can be used, as it measures various electrical values like voltage, current, and resistance.

Both technicians are partially correct.
A logic probe can be used to test the primary circuit as it can detect and indicate the presence of logic signals, such as pulses or high/low voltages.
A DMM (digital multimeter) can also be used to test the primary circuit as it can measure voltage, current, and resistance. However, it may not be able to detect the presence of logic signals.
Therefore, it depends on the specific needs and requirements of the testing situation. If logic signals need to be detected, a logic probe would be more appropriate. If voltage, current, and resistance measurements are needed, a DMM would be more appropriate.

The expected stress that would correspond to a strain of 0.000250 is 182 MPa.

To determine the modulus of elasticity for the material, we need to find the slope of the stress-strain curve between the two given points (a and b).

The slope between points a and b can be calculated using the following equation:

slope = (strain_b - strain_a) / (stress_b - stress_a)

Substituting the values given in the problem, we get:

slope = (0.000630 - 0.000170) / (134 - 35) = 0.00364

Therefore, the modulus of elasticity can be calculated as the slope times the proportional limit, which is given as 200 MPa in the problem:

modulus of elasticity = slope * proportional limit = 0.00364 * 200 = 0.728 GPa

To calculate the expected stress that would correspond to a strain of 0.000250, we can use the following formula:

stress = strain * modulus of elasticity

Substituting the values we have calculated, we get:

stress = 0.000250 * 0.728 GPa = 182 MPa

Therefore, the expected stress that would correspond to a strain of 0.000250 is 182 MPa.

Answer:

\(u = 260.22m/s\)

\(S_{max} = 1141.07ft\)

Explanation:

Given

\(S_0 = 89.6ft\) --- Initial altitude

\(S_{16.5} = 0ft\) -- Altitude after 16.5 seconds

\(a = -g = -32.2ft/s^2\) --- Acceleration (It is negative because it is an upward movement i.e. against gravity)

Solving (a): Final Speed of the rocket

To do this, we make use of:

\(S = ut + \frac{1}{2}at^2\)

The final altitude after 16.5 seconds is represented as:

\(S_{16.5} = S_0 + ut + \frac{1}{2}at^2\)

Substitute the following values:

\(S_0 = 89.6ft\)       \(S_{16.5} = 0ft\)     \(a = -g = -32.2ft/s^2\)    and \(t = 16.5\)

So, we have:

\(0 = 89.6 + u * 16.5 - \frac{1}{2} * 32.2 * 16.5^2\)

\(0 = 89.6 + u * 16.5 - \frac{1}{2} * 8766.45\)

\(0 = 89.6 + 16.5u- 4383.225\)

Collect Like Terms

\(16.5u = -89.6 +4383.225\)

\(16.5u = 4293.625\)

Make u the subject

\(u = \frac{4293.625}{16.5}\)

\(u = 260.21969697\)

\(u = 260.22m/s\)

Solving (b): The maximum height attained

First, we calculate the time taken to attain the maximum height.

Using:

\(v=u + at\)

At the maximum height:

\(v =0\) --- The final velocity

\(u = 260.22m/s\)

\(a = -g = -32.2ft/s^2\)

So, we have:

\(0 = 260.22 - 32.2t\)

Collect Like Terms

\(32.2t = 260.22\)

Make t the subject

\(t = \frac{260.22}{ 32.2}\)

\(t = 8.08s\)

The maximum height is then calculated as:

\(S_{max} = S_0 + ut + \frac{1}{2}at^2\)

This gives:

\(S_{max} = 89.6 + 260.22 * 8.08 - \frac{1}{2} * 32.2 * 8.08^2\)

\(S_{max} = 89.6 + 260.22 * 8.08 - \frac{1}{2} * 2102.22\)

\(S_{max} = 89.6 + 260.22 * 8.08 - 1051.11\)

\(S_{max} = 1141.0676\)

\(S_{max} = 1141.07ft\)

Hence, the maximum height is 1141.07ft

In this scenario, vehicles in three lanes are traveling at different speeds with a constant spacing between them.

By collecting spot speed data for 30 minutes as vehicles cross a specific observation point, we can calculate the time-mean speed and space-mean speed for the traffic stream.

To calculate the time-mean speed, we need to determine the average speed of all vehicles over the given time period. Since the speeds in each lane are constant, the time-mean speed will be the average of the speeds in each lane. In this case, lane 1 has vehicles traveling at 30 mph, lane 2 at 45 mph, and lane 3 at 60 mph. Thus, the time-mean speed can be calculated by taking the average of these speeds: (30 + 45 + 60) / 3 = 45 mph.

To calculate the space-mean speed, we need to consider the average speed of vehicles at a specific location along the roadway. In this scenario, the spacing between vehicles in each lane is constant at 0.5 mile. Therefore, the space-mean speed can be calculated by dividing the total distance traveled by all vehicles in the given time period by the total time taken. Since the vehicles maintain a constant speed, the total distance traveled will be the same as the time-mean speed. Hence, the space-mean speed in this case will also be 45 mph.

In summary, for the given traffic stream with different speeds in each lane and a constant spacing between vehicles, the time-mean speed and space-mean speed are both equal to 45 mph.

The engineering design process is a cyclical process, and the engineer may need to repeat steps or modify the design as new information is gathered or the requirements change. The process is iterative, meaning that the engineer may repeat the cycle of steps multiple times until a successful solution is developed.

The engineering design process is a systematic approach that engineers use to develop solutions to real-world problems. The process includes the following eight steps:
1. Define the Problem: In this step, the problem is identified and the purpose of the solution is established. Engineers consider factors such as the constraints, requirements, and objectives of the project.
2. Conduct Research: Once the problem is defined, engineers research existing solutions, materials, and technologies that may be useful in developing a solution.
3. Develop Requirements: Based on the research, the engineer develops a list of requirements that the solution must meet. These requirements may include constraints such as cost, size, weight, or environmental factors.
4. Brainstorm Possible Solutions: In this step, engineers use creative thinking techniques to develop multiple solutions to the problem.
5. Choose a Solution: After generating a list of possible solutions, the engineer evaluates each solution based on the requirements and selects the best solution.
6. Develop a Prototype: A prototype is a preliminary model of the solution. In this step, the engineer creates a physical or virtual model of the solution to test and refine it.
7. Test and Evaluate the Solution: In this step, the engineer tests the prototype to determine if it meets the requirements and solves the problem.
8. Refine the Solution: Based on the test results, the engineer refines the solution by making modifications to the design. This process may involve multiple iterations until the solution is fully developed.

Nested refers to a situation where one construct, such as a loop or conditional statement, is placed inside another construct of the same type. For example, a nested for loop is a loop within another loop, where the inner loop is executed multiple times for each iteration of the outer loop. Similarly, a nested if statement is an if statement within another if statement, where the inner if statement is only executed if the outer if statement evaluates to true. Nesting is a common programming technique used to solve complex problems by breaking them down into smaller, more manageable parts.

This program reads an integer inVal from input and then uses nested for loops to output each number from 0 to inVal, followed by a corresponding number of plus sign characters. The output for each number is ended with a newline character.

The outer for loop iterates from 0 to inVal, while the inner loop iterates from 0 to i - 1. For each iteration of the inner loop, a plus sign character is output, and after the inner loop, the current value of i is output on a new line. The number of plus sign characters output is determined by the current value of i, since the inner loop runs i times.

Therefore, the program outputs a sequence of numbers followed by a corresponding number of plus sign characters, where the number of plus sign characters for each number increases as the number increases.
