Summarize the difference in hydraulic and pneumatic systems.

Engineering
1 answer:
Naily [24]2 years ago
7 0

Answer:

The main difference between a pneumatic system and a hydraulic system lies in how the energy necessary to make these systems work is generated: thus, while in the pneumatic system this energy is generated through the compression of gases, in the hydraulic system the energy is obtained Through the insertion of pressurized fluids, such as water.  Furthermore, hydraulic systems are closed circuits, where the water constantly circulates within the system; while in pneumatic systems the air that is compressed and used is constantly renewed.

The way most recursive functions are written, they seem to be circular at first glance, defining the solution of a problem in te
EastWind [94]

Question Continuation

int factorial(int n) {

if(n == 0)

return 1;

else

return n * factorial(n - 1);

}

Provide a brief explanation why this recursive function works.

Show all steps involved in calculating factorial(3) using the function defined.

Answer:

1. Brief explanation why this recursive function works.

First, the recursive method factorial is defined.

This is the means through with the machine identifies the method.

The method is defined as integer, the machine will regard it as integer.

When the factorial is called from anywhere that has access to it, which in this case is within the factorial class itself. This means you can call it from the main method, or you can call it from the factorial method itself. It's just a function call that, well, happens to call itself.

2. Steps to calculate factorial(3)

1 First, 3 is assigned to n.

2. At line 2, the machine checks if n equals 0

3. If yes, the machine prints 1

4. Else; it does the following from bottom to top

factorial(3):

return 3*factorial(2);

return 2*factorial(1):

return 1;

Which gives 3 * 2 * 1 = 6

5. Then it prints 6, which is the result of 3!
