Q.2: Python: Classes

a) Moment of Inertia

Can you come up with centroid calculation that it includes the calculation of the two moments of inertia, Ix, and Iy.

b) Centroid

Please to write a centroid program which should ask the user to input a user-defined number of rectangles and calculate the centroid of the compound shape. Also, draw the rectangles using "turtle" so you can see if it is doing what you wanted.

c) Rectangle Class

Create a class to describe a rectangle. It doesn't have to be an actual Python class - you can just describe the important elements of the class.

Explanation / Answer

2a)    def momentOfInertia():
       ix = breadth * math.pow(length, 3)/12
       iy = length * math.pow(breadth, 3)/12

2b)

import turtle

# Rectangle class with length and breadth

class Rectangle(object):
   #constructor
   def __init__(self, length, breadth):
       self.length = length
       self.breadth = breadth
       #draw thw rectangle
       turtle.forward(self.breadth)
       turtle.left(90)
       turtle.forward(self.length)
       turtle.left(90)
       turtle.forward(self.breadth)
       turtle.left(90)
       turtle.forward(self.length)
       turtle.left(90)
   #calculating area  
   def getArea(self):
       return self.length*self.breadth
   #returns the objects of the class as a string
   def __str__(self):
       return length + " " + breadth
   def calculateCentroid():
       x = breadth/2;
       y = length/2;
       print("centroid: " + x + "," + y);
      
while(True):
   choice = input("1. Enter rectangle values 2. Exit)
   if choice == 1:
       len = int(input('Enter length: '));
       bre = int(input('Enter breadth: ));
       rec = Rectangle(len , bre);
       rec.calculateCentroid();
   elif:
       break;

2c)

# Rectangle class with length and breadth

class Rectangle(object):
   #constructor
   def __init__(self, length, breadth):
       self.length = length
       self.breadth = breadth
   #calculating area  
   def getArea(self):
       return self.length*self.breadth
   #returns the objects of the class as a string
   def __str__(self):
       return length + " " + breadth
