Machine with a natural frequency of 4.2 hz is subjected to a rotating imbalance force at afrequency of 4 hz and amplitude of 20 n. design a suitable dynamic vibration absorber for themachine, assuming that the available clearance for the motion of the absorber is 15 mm andthat the absorber uses up the entire clearance

oil flow is a highly convective flow compared to water flow at normal temperature and pressure.

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
