if the state of stress at a point is given by determien the stress vector and the magnitude of the normal and shear stress acting on the plane.
T=σ(x)n(x), where σ is the stress tensor and n is the outward unit normal to the surface at x, gives the stress vector t operating on a surface at a point x.
What do you mean by stress tensor?
The stress tensor, also known as the Cauchy stress tensor σ, genuine stress tensor, or simply the stress tensor in continuum mechanics, is made up of nine elements σ[tex]_{ij}[/tex] that collectively characterize the state of stress at a point inside a material that is in a deformed condition, location, or configuration. The stress tensor and traction vector have the SI unit, which corresponds to the stress scalar, N/m2. A unit vector has no dimensions.
Continued Answer:
The stress tensor σ and unit normal n are constant for all x on the plane, as you have already noticed. The tension vector t is therefore given by
t=σn= [tex]\left[\begin{array}{ccc}1&1&0\\1&1&1\\0&1&1\end{array}\right] \left[\begin{array}{ccc}\frac{1}{\sqrt{3}} \\ \frac{1}{\sqrt{3}} \\\frac{1}{\sqrt{3}} \end{array}\right] = \left[\begin{array}{ccc}\frac{2}{\sqrt{3}} \\\frac{2}{\sqrt{3}}\\\frac{2}{\sqrt{3}}\end{array}\right][/tex]
Since n has magnitude 1, the component of t that is perpendicular to the plane, c, can be calculated by
[tex]c = (t . n)n = \frac{7}{3}n[/tex]
The angle θ between the stress vector and the plane's normal is finally given by:
θ = [tex]cosx^{-1} (\frac{t . n}{|t| . |n|}) = cos^{-1}(\frac{7/3}{\sqrt{17}/\sqrt{3}})[/tex]

Land subsidence is worsened by the cessation of groundwater pumping, because the additional water that is retained underground weakens the rock, making it subside more easily. (False)
What is land subsidence?Land subsidence happens when a lot of groundwater has been taken out of particular kinds of rocks, like fine-grained sediments. Because water helps to hold the ground up in part, the rock compacts. The rocks collapse when the water is turned off.
Due to the fact that land subsidence can happen over wide areas as opposed to a single small area, like a sinkhole, you might not notice it too much. However, this does not imply that subsidence is not a significant occurrence; over the years, states like California, Texas, and Florida have sustained losses totaling hundreds of millions of dollars.

considering the physical channel structure, why does friction increase or decrease as the wetted perimeter increases?
Friction increase with increasing wetted perimeter. This is because increase in wetted perimeter means more water is coming in contact with surface. This increase the friction. If wetted perimeter is less, only a small portion of the water will come in to contact with surface. This will reduce friction.
What is friction?Friction is experienced by every moving object. Friction is the force preventing an object from sliding against another. Things move more slowly due to friction before coming to a complete stop. Friction makes it possible to move against a surface while driving or walking, which isn't always a bad thing. Friction is a necessary component of movement on Earth.
Applying an equal force in the opposite direction of the object's motion produces friction. The friction is moving against the push force, as shown in the diagram. The friction will cause the book to move more slowly before finally stopping it.

where a grounding electrode conductor or bonding conductor for a radio antenna system is installed in a metal raceway, the contained grounding electrode conductor is not required to be bonded to both ends of the raceway.
Both ends of the raceway shall be bonded to the contained conductor.
Where is the grounding conductor installed?On the supply side of the disconnecting method, a grounding electrode conductor must be attached to one or more of the following, depending on the situation, in a wireway or other accessible enclosure: Equipment grounding conductor(s) attached with the feeder. Grounded service conductor(s). Jumper supply-side bonding.
A conductive object that creates a direct connection to the earth or ground is what a grounding electrode essentially is. The fact that a grounding electrode is in direct touch with ground is crucial. A structure contains many conductive items, but not all of them establish a straight connection to ground.
If exposed to physical harm, a copper or aluminum grounding electrode conductor of 4 AWG or larger must be shielded.

Create a numpy array of sequential numbers from 0 to and including 99. Ensure the sequential numbers you have created are stored in a numpy multidimensional array of 2 numpy dimensions with a corresponding numpy shape of 20 by 5 elements. You must use the numpy features mentioned in this question to receive credit for this question. Submit your Python script according to the guidelines in this document as a .PY file with the following naming convention: ‘Q5-[ASURITE Id].py', where according to your ASU credentials, you will replace the text [ASURITE Id] in the above naming convention with your ASURITE id credential.
Numerous mathematical operations can be carried out on arrays with NumPy.
It provides a vast library of high-level mathematical functions that work on these arrays and matrices, as well as strong data structures that ensure efficient calculations with arrays and matrices. Shape, an attribute of NumPy arrays, returns a tuple containing the number of corresponding elements for each index. The bincount(arr) method in the numpy module of Python returns a count of the number of times each value in an array of non-negative ints has occurred. Every element in a NumPy array has the same data type. itemsize gives the size of each element of a NumPy array in bytes. For instance, the itemsize for this NumPy array [[3,4,6], [0,8,1]]

the fraction recrystallized-time data for the recrystallization at 350 of a previously defomred aluminim are tabulated here.
The fraction recrystallized after a total time of 116.8 min is 0.66.
What is recrystallization?The process of recrystallizing an impure compound in a solvent is also referred to as fractional crystallization. Based on the idea that most solids become more soluble at higher temperatures, the purification process was developed. The amount of solute that can dissolve in a solvent increases as temperature rises, according to this.
On the basis of the information provided in the problem, we will set up two simultaneous equations with two unknowns:
[tex]1n(1n - \frac{1}{1-0.3} ) = 1nk + n 1n \ 95.2[/tex]
[tex]1n(1n - \frac{1}{1-0.8} ) = 1nk + n 1n \ 126.6[/tex]
Using your calculator you should get values of n = 5.3 and
k = 1.2 × 10⁻¹¹
From these values we can now solve for the fraction recrystallization from:
[tex]y = 1 - e^{kt^n}[/tex]
[tex]= 1 - e^{-1.2\times 10^{-11}\times (116.8)^{5.3}[/tex]
= 0.66

Create Pipe. c class THis is c language programming!(1) main() function must1. create two pipes and make them global.2. create two child processes. Each child process will call one of the functions defined in (2) and (3) below.3. wait() for a child process to end. Then, send the SIGUSR1 signal to the (2) process before ending.(2) One function should have an integer variable that starts at 0. It should print ping: {value} then increment the value. It should write that value to a pipe and read the value back from the other pipe until the value is greater than or equal to 100. It should call exit() when complete.(3) The other function should set up a signal handler for SIGUSR1 to call a function (defined in (4) below) when it receives that signal. It should then loop forever: read from a pipe, print pong-{value}, increment the value and write the value to the other pipe. These pipes must be opposite from the function in (2): the pipe you write to in (2) must be the pipe that you read from in (3) and vice versa.(4) Create a function for the signal handler that should print pong quittingand then exit().
Put together Pipe. The two pipes are created using c program language , and they are made global.
