The state of plane stress at a point on a body can be depicted by the mohr's circle below. point x has coordinates (−10,−21) mpa and point y has coordinates (25,21) mpa.
determine the normal and shear stresses associated with a rotation of the stress element θ=28°. remember that a negative sign indicates a clockwise rotation and a positive sign indicates a counter-clockwise rotation. note that you can use the mohr's circle to obtain your answers graphically or you can apply the stress transformation equations.
determine the σx′, σy′ , and τx′y′

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
