CIn a traction drive, a 1.4-in.-diameter cylindrical roller is preloaded against a 3.4-in. diameter cylindrical roller. The steel rollers are 3.7 in. wide and the preload force is 56 lb. The axes of the cylinders are parallel. Calculate the maximum contact pressure in ksi.

The maximum contact pressure is 12.658 ksi

Explanation:

The contact modulus is:

Δ = M

The radius of curvature is:

r1 = D1/2 = 1.4/2 = 0.7 in

r2 = D2/2 = 3.4/2 = 1.7 in

The maximum contact pressure is:

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
