In an orthogonal cutting operation, the rake angle = -8°, chip thickness before the cut = 0.22 mm and width of cut = 3.2 mm. the cutting force is 1750n and the thrust force is 1200n. the chip ratio = 0.42. determine: a-the chip thickness after the cut (b)-shear angle (c)-coefficient of friction (d)-friction angle (e)-shear strain.

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
