Select a chain drive to transmit 2.5Kw from a gearbox running at 130 rev/min and driven by a direction on line electric motor to a uniformly loaded conveyor drive shaft which is required to run at approximately 60 rev/min for 16hours per day , gearbox output shaft is 45mm and the head shaft is 75mm diameter

can you make it more obvious. i can't see it properly

answer:

i am not 100% sure but i think it is a.)

dont take my word for it

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
