A manufacturer of pressure vessels is worried about his steel fracturing abruptly as the chambers are loaded to high pressures because the steel is heavily cold-rolled with a very high yield strength (σy > 1 GPa). He decides to measure the fracture toughness of his steel using a thick-compact tension sample (Y = 1.12). He puts a 100 µm crack in the specimen, loads it in tension, and measures a fracture toughness of 10 MPa m^1/2.
a. What was the fracture stress during this experiment?

answer:

design model: consists of design geometry; can be 2d or 3d; typically has a black background.

design files: drawing created with microsoft expression design, a drawing and design program for windows; may contain both vector and raster graphics; can also include multiple layers and various image effects.

elements: an element is a single part of a larger group.

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
