|Deforming a rectangle|
|Adding a cross brace to make triangles|
Then we had a look through our junk modelling box for more shapes. We reinforced a box with cross braces to make it stronger. They explored the strength of cylinders and found it depended on which way they were compressed. Next we will move onto a more scientific way of testing shapes (using weights) when we make some bridges.
|L can't compress the box as easily with the cross braces attached|
|R finds that a cylinder is very strong in this orientation|
