Understanding and Analysing Trusses. What is the first statement of the audio clip?
Trusses are everywhere.
They are used in bridges,
antenna towers,
cranes.
Even in parts of the International Space Station.
And for good reason.
They allow us to create strong structures while using materials in a very efficient
and cost-effective way.
