A specimen of a 4340 steel alloy has a plane-strain fracture toughness of 45 MPa√m. It is known that the largest surface crack in a plate of this specimen is 1.08 mm long. What is the maximum stress tensile normal to this crack that the specimen can tolerate without fracturing ? Assume that the geometric parameter Y has a value of 1.0. Answer Format: X (no decimal) Unit: MPa

answer:

constructing a building's framework requires a solid foundation

explanation:

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
