SCALE RATIO

 WHAT IS SCALE RATIO?


Scale ratio represents the proportional ratio of a linear dimension of  the model to the same feature of the original.This ratio  allows any researcher to compare the intervals or differences. 







THINK ON IT!

Scale drawing is a drawing that shows a real object with accurate sizes reduced or enlarged by a specific amount,this drawing is important because it is useful to plan,visualize and adjust landscape plans before breaking ground.Scale drawings is useful in real world scenarios to be used as an illustration of something that is drawn either smaller or larger than the original.For example,a scale drawing of a building would be drawn smaller than the original drawing,but in the same scale. One foot of the original building might be represented as one half-inch on the scale drawing.Scales used in drafting include mechanical engineer's scale,the civil engineer's scale, the architect's scale and the metric scale.Scale drawings show the actual size of an object.If the object is either too small or too large to draw full scale,the designer scales it up or down.Technical drawings are drawn to scale so that the engineer's, architect's and builders can create the objects in the drawing to exact specifications.

What is a Scale Ratio?

 A scale ratio, also known as a scale factor, refers a ratio between equivalent measurements of an object as well as an accurate depiction of said object. If the object is too large to draw on paper, scale ratios can be used to find a scaled-down, proportionate figure. Scale ratios can also be used on smaller objects to create a scaled-up drawing of it.

Why are scale drawings or models important?

Scale drawings/models are important as they are used as guides by those working within the creative fields (artists, designers, etc.) to create an object into a different size than it was originally. They are also used to provide a precise representation of a larger or smaller object in an accessible and less time-consuming way. For example, engineers can test a design concept by making a model instead of creating a life-sized prototype.

Scale drawings/models are useful in certain areas of work such as construction as it provides a way to communicate an exact plan for a design or look for an object in a visually pleasing manner.

Scale drawings and models are used by the following fields:


Why are they in important in these fields?

  • Architects & engineers- these professions utilize scaled technical drawings in order to communicate to the builder their design as well as the exact specifications & dimensions required.

  • Cartographers- Different varieties of scales such as bar scales, representative fractions (e.g., 1 / 600 000), or verbal wording (e.g., one inch to the mile) are used by cartographers to accurately describe & represent the size of geographic features on a map.

  •  Artists- Particularly painters or sculptors, use scale ratios to sketch temporary guides before starting a large or small scaled project. They also use scale in order to draw attention to their artwork as well as to make it aesthetically pleasing to the viewer.

 

SCALE RATIO

                                                                 Scale Ratio 


Scale ratio is the portrayal of a model that is being scaled down or up with the same features of the original model in that case it is a representation of that object.


A scale drawing helps you to see precisely how  everything will be and what kind of area you may have, each empty and filled. Whether you're addressing area concerns, including or rearranging additives or maybe operating on a couple of designs, scale will usually play a key function withinside the making plans of your project.


Scale drawing are useful in real world scenarios because according to if you want to see something scale down or up your will use a scale drawing eg. if you want to carry the Eiffel Tower to school for a project you can’t carry the real Tower so therefore you will need a scale down Eiffel Tower. 


It also allows you to see things easily, so that the scale drawings or models are made in the  context of real existence.as a scale drawing of an instance of something that is drawn both smaller or larger than the authentic. For example, a scale drawing of a construction could be drawn smaller than the authentic drawing, however at the equal scale. One foot of the authentic construction is probably represented as one-half-inch on the dimensions drawing.


How it It will translate in the real world or even if you wanted to add a playground

space for your kids a scale drawing can ensure that there's room for it to fit or

even show you how it will look in that space u desire to place it another benefit of

scale drawing is that you can make as many plans as you want ensuring that you

are mentally satisfied with the house or building that you want to achieve.




Many ask why scale drawings are important in these for (4) fields I have chosen


Construction- In the construction industry, a variety of scales are normally used relying on the character of the drawing.



Baking - Bakers use measurements in place of scale drawing when they are baking different sizes  of stuff e.g a 6 inch cake and a 24 inch cake.



Architecture - Architects use scale drawings because it enables them to recognize the relationship between a  physical design and the reality of its real world size. It is very rare an architectural drawing is not shown, without a blueprint, it would be really hard to construct a building. 



Fashion Designing -  Designers use scale drawing because in society everyone is not the same size so therefore that needs to be done to accommodate everyone.





Scale ratio= Dimensions of the model  ÷ by Dimensions of original object


Actual Rapunzel tower = 20 m

Model Rapunzel tower = 4 cm


Therefore every 1 cm in the model tower is equal 

to 5 m  in the actual tower

.Scale ratio: 1:5





Scale ratio= Dimensions of the model ÷ By Dimension of the original object

 Short Cup = 8 oz 

Grande Cup = 16 oz Therefore every 1 oz in the short cup

 is 2 oz in the grande cup 


Scale ratio: 1:2








Scale ratio= Dimensions of the model ÷

By Dimension of the original object


Large Dress = 120 cm

Small Dress = 3 cm


Therefore every 1 cm on the small

Dress is 4 cm on the large dress


scale ratio: 1:4




Scale ratio = Dimensions of the model  ÷

by Dimensions of the original object.


Actual Perfume Bottle = 12 cm

Model of Perfume Bottle = 6 cm


Scale ratio: 1:2

Scale Ratio



Mathematics: Scale Ratio


 Define It: 

The scale ratio of a model exemplifies the proportional ratio of a linear dimension of the model to the same feature of the original. The ratio scale refers to the position of measurement in which the attributes composing variables are measured on specific numerical scores or values that have equal distances between attributes or points along the scale. Examples such as a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. The scale can be stated in four words such as a ratio, lexical scale, a fraction and as bar scale. 

 

                                        

 

Think On It:

A scale drawing is a diagram of an object that is drawn either smaller or larger than the original. The use of similarity in scale drawings and models is elemental to creating products that are both useful and pleasing to the eye. Scale models also allow designers to make changes at a much smaller cost instead of showing the clients the final vision. If a drawing isn't to scale, there's no guarantee that each object will fit into the real area. A scale drawing lets you see exactly how each element will fit and how much space you will have, both empty and full, the designer scales it down. All the measurements in the drawing must correspond to the measurements of the actual object by the same scale 

 

 

 

 How Scale Drawings Are Used In The Real World:

They are used to create maps and other scale diagrams, when things are too big to draw on paper, scale factors are used to calculate smaller, proportional measurements, Scale drawings are a useful tool for any designer, because they can be used to plan, visualize and adjust landscape plans before breaking grounds or begin any construction. Scale drawings assign each object the same scale compared to the actual objects. 

 

Architecture- When an architect or a designer is building for a client, they must often create to the clients’ exact description. Scale drawings allow each object the same scale compared to the actual objects. When designing a landscape, one of the most important considerations are how it will translate to the real world. 

 

Chemistry-The scale allows the physicists to figure out the particles' level and also the burden of those particles. 

 

Art- As with elements such as unity and balance, artists use scale and proportion to carry their unique observation to the viewer. When an artist or designer chooses to make particular objects oversized or diminutive, it is often to emphasize their importance or encourage a new perspective. 

Carpenters- It is important that the scale used is noted on the drawing, because of the ease of reproducing, printing and altering drawings, it is important to note the original sheet size that the scale was drawn at.

Create It:

I used a model of Optimus Prime as an example to show how scale ratio is used in the real world. 

 

Model of Optimus Prime 

Height – 10cm 

Width – 3cm 

Length – 4cm 

 

Real Optimus Prime 

Height – 5m 

Width - 18m 

Length - 36m 

 

Scale Ratio Working: 

Height – 10/5 = 5 

Width – 8/3 = 6 

Length – 36/4 = 9                              

 

Scale Ratio: 

Height – 1:5 

Width - 1:6 

Length – 1:9
