Answer:

Option A

Chemical engineering

Explanation:

Chemical engineering mainly encompass the study of behavior of different particles such as petroleum, water, drugs and other products. When Anne is involved in a study with engineers who study flow of particles, the flow, viscosity and other properties are among the behavior that chemical engineers are involved in.

Write a simple calculator program. Your program should ask for three things two whole numbers and an operator in the form of an
vekshin1

Answer:

The solution code is written in Java.

  1.        Scanner input = new Scanner(System.in);
  2.        System.out.print("Enter operator: ");
  3.        String operator = input.nextLine();
  4.        System.out.print("Enter first integer: ");
  5.        int num1 = input.nextInt();
  6.        System.out.print("Enter second integer: ");
  7.        int num2 = input.nextInt();
  8.        int result = 0;
  9.        switch(operator){
  10.            case "+":
  11.               result = num1 + num2;
  12.               break;
  13.            case "-":
  14.                result = num1 - num2;
  15.                break;
  16.            case "*":
  17.                result = num1 * num2;
  18.                break;
  19.            case "/":
  20.                result = num1 / num2;
  21.                break;
  22.            default:
  23.                System.out.println("Invalid operator");
  24.        }
  25.        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>

A square plate of titanium is 12cm along the top, 12cm on the right side, and 5mm thick. A normal tensile force of 15kN is appli
lukranit [14]

Answer:

For the Top Side

- Strain ε  = 0.00021739

- Elongation is 0.00260868 cm

For The Right side

- Strain ε  = 0.00021739

-Elongation is 0.00347826 cm

Explanation:

Given the data in the question;

Length of the squared titanium plate = 12 cm by 12 cm = 0.12 m by 0.12 m

Thickness = 5 mm = 0.005 m

Force to the Top F_t = 15 kN = 15000 Newton

Force to the right F_r = 20 kN = 20000 Newton

elastic modulus, E = 115 GPa = 115 × 10⁹ pascal

Now, For the Top Side;

- Strain = σ/E = F_t  / AE

we substitute

= 15000 / ( 0.12 × 0.005 × (115 × 10⁹) )

= 15000 / 69000000

Strain ε  = 0.00021739

- Elongation

Δl = ε × l

we substitute

Δl = 0.00021739 ×  12 cm

Δl = 0.00260868 cm

Hence, Elongation is 0.00260868 cm

For The Right side

- Strain = σ/E = F_r  / AE

we substitute

Strain = 20000 / ( 0.12 × 0.005 × (115 × 10⁹) )

= 20000 / 69000000

Strain ε = 0.000289855

- Elongation

Δl = ε × l

we substitute

Δl = 0.000289855×  12 cm

Δl = 0.00347826 cm

Hence, Elongation is 0.00347826 cm
