By driving a truck over a scale, it was determined that the loads on the front and rear axles are 18 kn and 12 kn, respectively, when the truck is empty. determine the weight and the location of the heaviest load that the truck can carry if the load on each axle is not to exceed 40 kn. three forces and a couple act on crank abc. determine the value of d so that the given system of forces is equivalent to zero at (a) point b, (b) point d.

answer: a

a is the answer

answer:

i am.. love turtles

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
