Answer: (b)
Explanation:
Given
Original length of the rod is
Strain experienced is
Strain is the ratio of the change in length to the original length
Therefore, new length is given by (Considering the load is tensile in nature)
Thus, option (b) is correct.
Answer:
Here is the JAVA program:
import java.util.Scanner; // to take input from user
public class VectorElementOperations {
public static void main(String[] args) {
final int NUM_VALS = 4; // size is fixed that is 4 and assigned to NUM_VALS
int[] origList = new int[NUM_VALS];
int[] offsetAmount = new int[NUM_VALS];
int i;
//two lists origList[] and offsetAmount[] are assigned values
origList[0] = 20;
origList[1] = 30;
origList[2] = 40;
origList[3] = 50;
offsetAmount[0] = 4;
offsetAmount[1] = 6;
offsetAmount[2] = 2;
offsetAmount[3] = 8;
String product=""; // product variable to store the product of 2 lists
for(i = 0; i <= origList.length - 1; i++){
/* loop starts with i at 0th position or index and ends when the end of the origList is reached */
/* multiples each element of origList to corresponding element of offsetAmount and stores result in the form of character string in product*/
product+= Integer.toString(origList[i] *= offsetAmount[i]) + " "; }
System.out.println(product); }} //displays the product of both lists
Output:
80 180 80 400
Explanation:
If you want to print the product of origList with corresponding value in offsetAmount in vertical form you can do this in the following way:
import java.util.Scanner;
public class VectorElementOperations {
public static void main(String[] args) {
final int NUM_VALS = 4;
int[] origList = new int[NUM_VALS];
int[] offsetAmount = new int[NUM_VALS];
int i;
origList[0] = 20;
origList[1] = 30;
origList[2] = 40;
origList[3] = 50;
offsetAmount[0] = 4;
offsetAmount[1] = 6;
offsetAmount[2] = 2;
offsetAmount[3] = 8;
for(i = 0; i <= origList.length - 1; i++){
origList[i] *= offsetAmount[i];
System.out.println(origList[i]); } }}
Output:
80
180
80
400
The program along with the output is attached as screenshot with the input given in the example.
