Answer:
One sheave means that you are using a single drum winder. They are the worst! Double drum winders control easier, brake better and are much more efficient. They save time ( two skips or cages) and can be clutched to perform faster shift transport. A single drum is slow, unbalanced and can be a nightmare if it trips out during hoisting. If the brake system is not perfect it can be a real hairy experience. For a runaway single drum, there is no counterbalance effect. It always runs to destruction. With a double drum, the driver still has a chance to control the winder to a certain extent and he has two sets of brakes to rely on. A single sheave could also mean a shaft with a single compartment. No second means of escape unless there are ladders or stairways. Not a very healthy situation.
Those are just a few points. I am sure much more can be said in favor of a double drum winder and two or more sheaves in the headgear. Most of the shafts I have worked at have multiple winders and up to ten compartments. They all have a small single drum service winder for emergencies and moves of personnel during shift times. They are referred to as the Mary - Annes. Apparently, the name originated in the U.K. where an aristocratic mine owner named the first such winder after his mistress.

Images help tell a story where describing with words is either too lengthy, or practically impossible. For instance, you could have a map of a location and various arrows and other markings to describe movements of troops during a battle of the civil war. This is one example of many that you could have as an image on a website. Describing the troop movements with words only may be really difficult to do. Plus many people are visually oriented learners, so they benefit with images every now and then. Of course, it's best not to overdo things and overload the site with too many images. A nice balance is needed.

Answer:
Following are the program to this question:
#include <iostream>//defining header file
using namespace std;
void squareOfAsterisks(int x) //defining method squareOfAsterisks
{
int i,j; //defining integer variable
for(i=1;i<=x;i++) //defining loop to print column value
{
for(j=1;j<=x;j++) //defining loop to print row value
{
cout<<"*"; //print value
}
cout<<endl; //for line break
}
}
int main() //defining main method
{
int x; //defining integer variable
cout<<"Enter any number: "; //print message
cin>>x; //input value from user
squareOfAsterisks(x); //calling the method and pass the value
return 0;
}
Output:
Enter any number: 4

Explanation:
The description of the above program can be given as follows:
- In the given program a method "squareOfAsterisks" is declared, that accepts an integer value "x" in its arguments, inside the method two integer variable I, j is used, that uses a to print the given pattern.
- In the main method, an integer variable x is declared, which takes input from the user end, and then calls the method, that is "squareOfAsterisks" and passes its value.
Answer:
It can be "ON" or "OFF". So it can store the numbers 1 and 0, but it certainly doesn't have the capacity to store a letter of the alphabet.
