SCALE RATIO BLOG: BY KHADIJA ALI

DEFINE IT.

A SCALE RATIO is a number by which the size of any geometrical figure or shape can be changed with respect to its original size. When things are too large, we use scale factors to calculate smaller, proportional measurements. It is used to compare two similar geometric figures.

THINK ON IT!!

WHY ARE SCALE DRAWINGS OR MODELS IMPORTANT?

Scale drawings allow us to accurately represent sites, spaces, buildings, and details to a smaller or more practical size than the original. A scale model provides a visual perspective that you can't achieve with blueprints and drawings.

HOW ARE THEY USEFUL IN REAL-WORLD SCENARIOS?

They are useful to create maps and other scale diagrams. Ratios are frequently used in our real world to simplify problems by expressing numbers in their correct perspective. We as humans never realize that we use it nearly every day because it allows us to measure and express quantities by making it much easier to understand in real-world scenarios. 

LIST FOUR FIELDS IN WHICH SCALE DRAWINGS OR MODELS ARE USED.

ARCHITECTURE,

MILITARY COMMAND,

ENGINEERING,

FILMMAKING.

WHY ARE THEY IMPORTANT IN THESE FIELDS?

ARCHITECTURE is both the process and the product of planning, designing, and constructing buildings or other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art.

MILITARY COMMAND is an organizational unit for which a military commander is responsible. A commander is normally specifically appointed to the role in order to provide a legal framework for the authority bestowed.

ENGINEERING is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering.

FILMMAKING is the process by which a motion picture is produced. Filmmaking involves a number of complex and discrete stages, including an initial story, idea, or commission.it then continues through screenwriting, casting, and pre-production.

SCALE DRAWINGS AN MODEL OF A BUTTERFLY.

ACTUAL BUTTERFLY- 6 cm in height

                                          9 cm in width

MODEL OF BUTTERFLY- 8 cm in height

                                              12 cm in width

     

SCALE DRAWINGS AN MODEL OF THE PARIS EIFFEL TOWER.

REAL EIFFEL TOWER- 30,000 cm in heigth

                                       - 1230 cm in width

MODEL OF PARIS EIFFEL TOWER- 20 cm in height

                                                             - 10 cm in width

SCALE DRAWINGS AN MODELS OF A CAR.

ACTUAL CAR- 149.5 cm in height

                         - 173.5 cm in width

MODEL OF THE CAR- 15 cm in height

                                      - 10 cm in width

PRINKLES PAN- 24 cm in height

                            - 8 cm in width

DRAWINGS OF PRINKLES PAN- 12 cm in height

                                                        -  4 cm in width

  

PRINKLES PAN SCALE RATIO WORKING:

 Height- 24 cm divide by 12 cm = 2

 Width- 8 cm divide by 4 cm = 2

SCALE RATIO IN 1 CENTIMETER FOR A PRINKLES PAN=1:2
