A) using singularity functions, write a single equation for m(x) along the beam. hint: use the constant ‘w’ for 30 lb/in and ‘ l’ for 120 in.; it will make the algebra in the next couple of parts much easier.
b) find the reactions at a and b.
c) find the deflection of the beam at x=120 in. if it is an s-beam (s24x80 structural steel; e = 29 x 106 psi; i = 2100 in4).

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

I would say until you turn pinK?? Also I hope your wood chuck is okay, I have essential oils if you want them!? July 4 should be on the 4th of July.
