Problem 6.3 (dimensioning of a shaft under torsion and bending): consider a cylindrical, solid transmission shaft working in torsion coupled with bending. the most loaded cross-section is subjected to a couple m having components mt , 0, mb along principal axes with mt denoting the torque component and mb the bending component; the magnitude of the couple is m = 10 kn · m. the allowable stress is σa = 50 mpa and an equivalent (von mises) stress is defined as σeq = √ σ2 + 4τ 2 where σ and τ respectively refer to the normal stress and shear stress acting on the cross-section. dimension the radius r of the shaft.

update this is wrong answer idk the answer

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
