What can spaghetti tell you about engineering? Mechanical engineer Shanice O’Mara introduces how engineering enables different kinds of bridges to successfully distribute weight of their load throughout their structures.
“They must be able to manage the forces of compression and tension, which means pushing and pulling so they don’t buckle or break. This can be achieved using a range of shapes and components which can be seen in bridges around the world.”
She then meets with three Dyson engineers, each with a spaghetti bridge that is put to the test with a few bags of sugar. The largest bridge is a spaghetti replica of San Francisco’s Golden Gate Bridge.
Build your own spaghetti bridge next. You’ll need spaghetti, tape, rubber bands, and a bag of sugar (or something similar) to put your structure to the test.
