Aline shaft rotating at 200 r. p.m. is to transmit 20 kw. the allowable shear stress for the material of the shaft is 42 mpa. if the shaft carries a central load of 900 n and is simply supported between bearing 3 metre apart, determine the diameter of the shaft. the maximum tensile or compressive stress is not to exceed 56 mpa.

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
