A cylindrical specimen of a brass alloy 8.3 mm (0.33 in.) in diameter and 76.7 mm (3.02 in.) long is pulled in tension with a force of 7360 N (1655 lbf); the force is subsequently released.
(a) Compute the final length of the specimen at this time. The tensile stress-strain behavior for this alloy is shown in Animated Figure 7.12.
(b) Compute the final specimen length when the load is increased to 20300 N (4563 lbf) and then released.

Why wont my java program print out anything past "please enter a group of at least 5 integers"?

import java.util.Scanner;

public class MyStatistics {

       Scanner sc=new Scanner(System.in);
       System.out.println("Please enter a group of at least 5 integers.");

       int[] int_array = new int[5];
       int sum_val = 0;
       int mean_val = 0;

The company publishes one regional magazine each in Upper North island (UN), Lower North island (LN), Upper South island (US), and Lower South island (LS). The company has 300,000 customers (subscribers) distributed throughout the four regions. On the first of each month, an annual subscription INVOICE is printed and sent to each customer whose subscription is due for renewal. The INVOICE entity contains a REGION attribute to indicate the customer’s region of residence (UN, LN, US, LS):

CUSTOMER (CUS_NUM, CUS_NAME, CUS_ADDRESS, CUS_CITY, CUS_REGION, CUS_SUBSDATE)

INVOICE (INV_NUM, INV_REGION, CUS_NUM, INV_DATE, INV_TOTAL)

The company is aware of the problems associated with centralized management and has decided that it is time to decentralize the management of the subscriptions in its four regional subsidiaries. Each subscription site will handle its own customer and invoice data. The management at company headquarters, however, will have access to customer and invoice data to generate annual reports and to issue ad hoc queries, such as:

•           List all current customers by region.

•           List all new customers by region.

•           Report all invoices by customer and by region.

Given these requirements, how must you partition the database? How many fragments will you create? Design the database fragments for the INVOICE table and show two rows of sample data for each fragment.

matching Document or do not document A)indicate whether or not you need to document in the following situation:you change a lot of the wording of a paragraph.B)indicate whether or not you need to document in the following situation: you list the birthplace of George Washington.C)indicate whether or not you need to document in the following situation: you use a sentence from a speech you got from an audio web site.D) indicate whether or not you need to document in the following situation: you're not sure whether you should document a source or not.

Hi it's the java stack to convert from infix to postfix

If I want to fix this code to calculate each numbers not just displaying the numbers what should I do?

Would you help me to fix the result?

//Function to return precedence

Real Shocks and the ‘Keynesian Cross’

Suppose the economy of Canada has reached the long-run equilibrium (i.e. full employment) and assume that the function of exports and imports are as follows:

(1) EX =α0 +α1q+α2(Y∗ −T∗)

(2) IMP =β0 −β1q+β2(Y −T)

where q is the real exchange rate between Canadian and US goods, Y − T is the Canadian disposable income, Y ∗ − T ∗ is the US disposable income, and the α’s and the β’s are positive parameters.

Assume that Prime Minister Trudeau decides to implements a temporary policy that convinces Canadians to buy less imported goods at any given real exchange rate and any given level of disposable income. In particular, assume that this policy lowers β0 in the import function shown above.

Explain how this temporary shock affects the level of output, consumption, investment, government expenditure, the nominal interest rate, the nominal and real exchange rates, and the level of prices in the short run. Use the AA-DD model to answer this question and do not forget to use a diagram to support your answer.

JAVA

Implement and test the following static recursive methods.

1) DigitCount – find the sum of the digits in an integer digitCount(12345) would be 5

2) Power2 - Efficiently compute exponentiation for non-negative exponents by the following recursive algorithm:

bx = 1 if x == 0

bx = (b(x/2))2 if x is even bx = b * (b(x-1)) if x is odd

3) Write a recursive method isBackwards that has two String parameters and returns true if the two Strings have the same sequence of characters but in the opposite order (ignoring white space and capitalization), and returns false otherwise. The method should throw an IllegalArgumentException if either String is null.

Test this method with following examples, isBackwards("Fried", "deirf") -> true isBackwards("Sit", "Toes") -> false isBackwards("", "") -> true

isBackwards("I madam", "mad am I") -> true
