A four-lane freeway is located on rolling rural terrain and has two 12-ft lanes in each direction and no lateral obstructions within 8 ft of the right-hand lane. The traffic stream consists of cars and trucks. A peak-hour volume of 3600 vehicles is observed in the major direction, with 1000 arriving in the most congested 15-min period. TRD=0.24 ramps/mi. If any data are missing, adopt default values from Table 3.3 a. What is the PHF?
b. What is the density of the peak hour traffic?
c. At what level of service is the freeway operating?
d. Ifa level of service no worse than C is desired, how many lanes are needed in each direction?

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

answer:

constructing a building's framework requires a solid foundation

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
