Ahelical compression spring is to be made of oil-tempered wire of 4-mm diameter with a spring index of c = 10. the spring is to operate inside a hole, so buckling is not a problem and the ends can be left plain. the free length of the spring should be 80 mm. a force of 50 n should deflect the spring 15 mm. (a) determine the spring rate. (b) determine the minimum hole diameter for the spring to operate in. (c) determine the total number of coils needed. (d) determine the solid length. (e) determine a static factor of safety based on the yielding of the spring if it is compressed to its solid length.

answer:

yes that is right have a good day

answer:

my guess it 8 i'm probably wrong

answer:

a

explanation:

it a unlucky day

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
