What is a mechanical gear and how does it work to create more power?

Neko [114]

Its a gear that is not turned manually and it can spin faster and longer than a manual gear.

The function of a start winding in a split-phase motor is to A. provide the starting torque. B. reduce the starting current. C.

gulaghasi [49]

The most appropriate answer is A, the the start winding on a split-phase motor is to provide a starting torque. A split-phase motor is a single phase electrical motor (common in many household applications such as washing machines and household fans), with two distinct windings on the stator coils, the start windings and the run windings, at 90 degrees apart. When the motor is energised the start coils acts like a second phase (2 phase motor) and helps provide the rotating magnetic field that is necessary to turn the rotor. Once moving, only the run winding (single phase) is required to keep the motor spinning.

The other answers are irrelevant for the starting of the motor.

Answer:

See explaination

Explanation:

// LetterCount.java

import java.io.File;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.NoSuchElementException;

import java.util.Scanner;

public class LetterCount {

public static void main(String[] args) {

// setting up a Scanner to read from keyboard

Scanner scanner = new Scanner(System.in);

try {

// asking and reading input file name

System.out.print("Enter name of input file: ");

String file = scanner.nextLine();

// reinitializing scanner to read from input file. this will throw

// file not found exception if file is not found.

scanner = new Scanner(new File(file));

// opening a file writer to create and write into output.txt file

PrintWriter writer = new PrintWriter(new File("output.txt"));

// creating a String containing all 26 alphabets

String alphabet = "abcdefghijklmnopqrstuvwxyz";

// creating an array containing 26 integers, all initialized to 0

int counts[] = new int[26];

// looping through the file

while (scanner.hasNext()) {

// reading next line, converting to lower case

String word = scanner.next().toLowerCase();

// looping through each character in current word

for (char c : word.toCharArray()) {

// finding index of c in alphabet

int index = alphabet.indexOf(c);

// if c is an alphabet, the index value will not be -1

if (index != -1) {

// incrementing counter at index position

counts[index]++;

}

// closing input file

scanner.close();

int largestCount = 0; // to store largest count of a character

String mostCommon = ""; // to store the character(s) that occur the

// most

// looping through counts array, finding the largest value

for (int i = 0; i < counts.length; i++) {

if (counts[i] > largestCount) {

// updating largestCount and mostCommon

largestCount = counts[i];

mostCommon = alphabet.charAt(i) + "";

} else if (counts[i] == largestCount) {

// same largest count, appending to mostCommon string

mostCommon += " " + alphabet.charAt(i);

}

// writing results to output file

writer.println("The most common letter(s): " + mostCommon);

writer.println("Count of occurrances: " + largestCount);

// closing file, saving changes, alerting user

writer.close();

System.out

.println("done! please check output.txt file for results.");

} catch (IOException e) {

// will be executed when the input/output file cant be opened or

// found, or if there is an error while reading the file

System.out.println(e.getMessage());

} catch (NoSuchElementException e) {

// will occur when there is no input provided for input file name.

System.out.println("No input!");

Design a RomanNumerals class that takes a number within 1 to 10 and display the Roman numeral version of that number (I, II, III

Alla [95]

Answer:

Explanation:

The following code is written in Java. It creates a RomanNumberals class with all of the requested methods, including a convertNum method and displayResults method. The user is then asked to input a number within the main method. A RomanNumeral object is created, passed the userInput and all of it's methods are called for testing. A test output can be seen in the attached image below.

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter a number: ");

int number = in.nextInt();

RomanNumerals romanNumeral1 = new RomanNumerals();

romanNumeral1.setNumber(number);

System.out.println("Test getNumber Method: " + romanNumeral1.getNumber());

romanNumeral1.convertNumber();

romanNumeral1.displayResult();

}

class RomanNumerals {

int number;

String romanNumeral;

public RomanNumerals() {

}

public int getNumber() {

return number;

}

public void setNumber(int number) {

this.number = number;

}

public void convertNumber() {

switch (this.number) {

case 1: romanNumeral = "I"; break;

case 2: romanNumeral = "II"; break;

case 3: romanNumeral = "III"; break;

case 4: romanNumeral = "IV"; break;

case 5: romanNumeral = "V"; break;

case 6: romanNumeral = "VI"; break;

case 7: romanNumeral = "VII"; break;

case 8: romanNumeral = "VIII"; break;

case 9: romanNumeral = "IX"; break;

case 10: romanNumeral = "X"; break;

default: System.out.println("Not a valid number"); break;

}

public void displayResult() {

System.out.println("Number " + this.number + " is represented as " + this.romanNumeral);

}
