To become familiar with the general equations of plane strain used for determining in-plane principal strain, maximum in-plane s
hear strain, and average normal strain. The state of strain at a point has components of ϵx=380.0×(10−6), ϵy=−250.0×(10−6), and γxy=180.0×(10−6).a. Equivalent in-plane strains on the oriented element Determine the equivalent in-plane strains on an element rotated counterclockwise at an angle of θ = 60.0 ∘ . Find ϵx',ϵy', γxy' Express your answers, separated by commas, to three significant figures.b. In-plane principal strains on the oriented element Determine the in-plane principal strains on the oriented element. Find ϵ1, ϵ2. Express your answers, separated by a comma, to three significant figures.c. Maximum in-plane shear strain and average normal strain on the oriented element Determine the maximum in-plane shear strain and the average normal strain on the oriented element. Express your answers, separated by a comma, to three significant figures.

Answer:
// Scanner class is imported to allow program
// receive input
import java.util.Scanner;
// RomanNumerals class is defined
public class RomanNumerals {
// main method that signify beginning of program execution
public static void main(String args[]) {
// Scanner object scan is created
// it receive input via keyboard
Scanner scan = new Scanner(System.in);
// Prompt is display asking the user to enter number
System.out.println("Enter your number: ");
// the user input is stored at numberOfOrder
int number = scan.nextInt();
// switch statement which takes number as argument
// the switch statement output the correct roman numeral
// depending on user input
switch(number){
case 1:
System.out.println("I");
break;
case 2:
System.out.println("II");
break;
case 3:
System.out.println("III");
break;
case 4:
System.out.println("IV");
break;
case 5:
System.out.println("V");
break;
case 6:
System.out.println("VI");
break;
case 7:
System.out.println("VII");
break;
case 8:
System.out.println("VIII");
break;
case 9:
System.out.println("IX");
break;
case 10:
System.out.println("X");
break;
// this part is executed if user input is not between 1 to 10
default:
System.out.println("Error. Number must be between 1 - 10.");
}
}
}
Explanation:
The program is well commented. A sample image of program output is attached.
The switch statement takes the user input (number) as argument as it goes through each case block in the switch statement and match with the corresponding case to output the roman version of that number. If the number is greater 10 or less than 1; the default block is executed and it display an error message telling the user that number must be between 1 - 10.
