UnconsciousIncompetence = you don't know that you can't do it well.
ConsciousIncompetence = you know you can't do it well.
ConsciousCompetence = you do it well, and you think about the work as you do it.
UnconsciousCompetence = you're so successful it's "automatic" -- you do it well, without thinking about it.
Answer:
The solution code is written in Java.
- Scanner input = new Scanner(System.in);
- System.out.print("Enter operator: ");
- String operator = input.nextLine();
- System.out.print("Enter first integer: ");
- int num1 = input.nextInt();
- System.out.print("Enter second integer: ");
- int num2 = input.nextInt();
-
-
- int result = 0;
-
- switch(operator){
- case "+":
- result = num1 + num2;
- break;
- case "-":
- result = num1 - num2;
- break;
- case "*":
- result = num1 * num2;
- break;
- case "/":
- result = num1 / num2;
- break;
- default:
- System.out.println("Invalid operator");
-
- }
-
- System.out.println(result);
Explanation:
To ask for the user input for two whole numbers and an operator, we can use Java Scanner class object. Since the input operator is a string, we can use nextLine() method to get the operator string (Line 3). We use nextInt() method to get whole number input (Line 5 & 7).
Next we use the switch keyword and pass the operator into the switch structure to determine which case statement should be executed. For example, if the input operator is "*" the statement "<em>result = num1 * num2;</em>
" will run and multiply <em>num1</em> with <em>num2. </em>
In surface mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore quantity.

Explanation:
deflection=8P*DN/Gd^4
G(for steel)=70Gpa=70*10^9N/m^2=70KN/mm^2
for outer spring,
deflection=8*3*50^3*5/(70*9^4)=32.66mm
for inner spring
deflection=8*3*30^3*10/(70*5^4)=148.11mm
max stress=k*8*P*C/(3.14*d^2)
for outer spring
c=50/9=5.55
k=(4c-1/4c-4)+.615/c=1.2768
max stress=1.2768*8*3*5.55/(3.14*9^2=.66KN.mm^2
for inner spring
c=6
k=1.2525
max stress=2.29KN/mm^2
