Bridge Reflection:

A horizontal rigid bar ABC is pinned at end A and supported by two cables at points B and C. A vertical load P 5 10 kN acts at e

BARSIC [14]

Answer:

vertical load = 10 kN

Modulus of elasticity = 200GPa

Yield stress on the cable = 400 MPa

Safety factor = 2.0

Explanation:

Data

let L = $\sqrt{(1.5)^{2} + (1.5)^{2} }$

= 3.35 m

substituting 1.5 m for h and 3 m for the tern (a + b)

$\theta$ = tan⁻¹( $\frac{1.5}{1.5}$ )

= 45⁰

substituting 1.5 for h and 3 m for (a+ b) yields:

$\theta$ ₂ = tan⁻¹ ( $\frac{1}{3}$ )

=25.56⁰

checking all the forces, they add up to zero. This means that the system is balanced and there is no resultant force.

Question 3. Assign boston_under_10 and manila_under_10 to the percentage of rides that are less than 10 minutes in their respect

Sever21 [200]

Answer:

Enter the following code to get the required conditions for the answer.

boston_under_5_height = 1.2

manila_under_5_height = 0.6

boston_5_to_under_10_height = 3.2

manila_5_to_under_10_height = 1.4

boston_under_10 = boston_under_10 = 5*boston_under_5_height + 5*boston_5_to _under_10_height

manila_under_10 = manila_under_10 = 5*manila_under_5_height + 5*manila_5_to _under_10_height

Explanation:

Kindly note that question in complete as it belong to the topic of table manipulation and visualization topic. The question asks about the company called Uber and their data extraction from the website called movements.uber.com where data was extracted for 200,000 weekdays in the respective cities of Manila, Philippines and Boston, Massachusetts. Images attached contains the histograms generated for the rides in manila and boston.

import java.util.*;

import java.lang.*;

import java.io.*;

public class Linc

{

static int size=4;

static int numBoxes = 1; // one row.

static int height =(int) Math.pow(size, 2); //Just how many | will it have.

static int width = 2; // two boxes in a row

public static void main (String[] args) throws java.lang.Exception

{

top();

printHeight();

}

public static void top(){

for(int i = 0; i <= numBoxes*width;i++)

{

if(i%width == 0) {//When this happens we're in a new box.

System.out.print(" ");

System.out.print("____________");

}

else

System.out.print(" ");

}

System.out.println(); //Move to next line.

}

public static void printHeight(){

for(int j = 0; j < height;j++){

for(int i = 0; i <= numBoxes*width;i++)

{

if(i%width == 0) {

System.out.print("|"); //Whenever this happens we're in a new box.

System.out.print("____________");

}

else

System.out.print(" ");

}

System.out.print("|");
