Answer:
70,900
Explanation:
Given :
True stress (psi) _____ True strain (psi)
48400 ______________ 0.11
60400 ______________ 0.19
Using ratio simplification :
Let :
s = True stress ; t = true strain
s1 = 48400
s2 = 60400
t1 = 0.11
t2 = 0.19
True stress, s0 ; needed to produce a True plastic strain, tp = 0.26
(s0 - s1) / (s2 - s1) = (tp - t1) / (t2 - t1)
(s0 - 48400)/(60400 - 48400) = (0.26 - 0.11)/(0.19 - 0.11)
(s0 - 48400)/12000 = 0.15/0.08
Cross multiply :
0.08(s0 - 48400) = 0.15 * 12000
0.08s0 - 3872 = 1800
0.08s0 = 1800 + 3872
0.08s0 = 5672
s0 = 5762 / 0.08
s0 = 70,900
The true stress required to produce a true plastic strain of 0.26 is 70,900
Answer:
- import java.util.Scanner;
- public class TryToParseDouble {
-
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- double num;
-
- try{
- System.out.print("Input a number: ");
- num = Double.parseDouble(input.nextLine());
-
- }catch(NumberFormatException e){
- num = 0;
- System.out.println("Invalid input! It should be a number in double type");
- }
- System.out.println(num);
- }
- }
Explanation:
Firstly, create a Scanner object to get user input (Line 5).
Next, create a try block and prompt user to input a number and use Double.parseDouble() method to convert the input to double type in the block (Line 8-10).
Next, create a catch block to catch a NumberFormatException. In the Catch block, set the num to zero and then print out a message to inform user about the invalid input (Line 12-14).
Lastly, display the number (Line 16).
Answer:
Explanation:
In electrical terms, is the ratio of time in which a load or circuit is ON compared to the time in which the load or circuit is OFF.
The duty cycle or power cycle, is expressed as a percentage of the activation time. For example, a 70% duty cycle is a signal that 70% of the time is activated and the other 30% disabled. Its equation can be expressed as:
