Question 32
Ben is testing different rulers. He wants to find out which ruler is the most flexible. He bends each ruler upwards and uses a stack of bricks to measure the height of the raised end. More bricks means a greater bend in this test. These are his results.
| Ruler | Number of bricks |
|---|---|
|Wooden ruler|2|
|Thin plastic ruler|7|
|Thick plastic ruler|5|
|Metal ruler|3|
Refer to Ben’s results in the Focus exercise.
Two of the rulers were plastic. Why did they not bend by the same amount?
