The scale drawing length of 4 centimetres represents the corresponding length of 5 metres on the real object. Work out the scale that has been used and write it in its simplest form. Write...
In order to interpret and produce scale drawings, you need to know the scale factor and the actual lengths of the object. For example, below is a scale drawing of a rectangular pool with a scale of 1 \, cm \, \text{:} \, 2 \, m or 1 \, \text{:} \, 200.
It is worth noting that scale drawings represent the same units. So, if a drawing is at 1:50 in cm, 1 cm in the drawing will be equal to 50 cm in real life. Similarly, if a drawing is in mm, at 1:200 – a 1 mm unit in the drawing will represent 200 mm in real life.
15 sie 2020 · The new scale drawing should be 30 cm by 12 cm, because \(3\cdot 10=30\) and \(3\cdot 4=12\). Since the length and width are 3 times as long, the area of the new scale drawing will be 9 times as large as the area of the original scale drawing, because \(3^{2}=9\).
A four-bevel scale has four scale ratios; two are on each side. A triangle scale can have the largest scale ratio range because it has three sides, and each side can have up to two scale ratios. SCALE NOTATION. The scale of a drawing denotes its size relationship to the object it is representing.
Measurement using a vernier. For taking reading using a vernier scale note the division on the vernier scale that coincides with some division of the main scale. Multiply this number of vernier division with the vernier constant. This is the vernier scale reading.
In this lesson, they extend this work in two ways: They compare areas of scale drawings of the same object with different scales. They examine how much area, on the actual object, is represented by 1 square centimeter on the scale drawing. For example, if the scale is 1 cm to 50 m, then 1 cm\(^2\) represents \(50\cdot50\), or 2,500 m\(^2\).
