softwood and hardwood- the names of these types of timber can be misleading as it does not refer to the density of the wood (e.g balsa wood is a hardwood). Softwood trees are gymnosperms which means they produce seeds with no covering. Hardwoods are angiosperms meaning they produce seeds with coverings (like an acorn).!
Steel! ub- universal beam! uc- universal column!
!
pfc- parallel flange channel!
tfc- tapered flange channel!
!
chs- circular hollow section! rhs- rectangular hollow section! shs- square hollow section!
!
flange and web- both are elements of the ‘I’ beam, also known as a universal beam. The horizontal elements are known as the flange and the vertical elements known as the web.!

CLASSROOM ACTIVITY ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! The purpose of this activity was to build the tallest structure out of the provided material while trying to use the least amount possible. The structure also needed to house a dinosaur so there needed to be an opening.!
!
It became apparent that different structures were going to be more structurally sound and stable than others due to their design. Our tower took an efficient method but lacked execution. The tallest in the class was similar to ours but executed effectively. !
!
A few other groups failed. I believe this is because of their design not allowing the load to properly travel to the ground or their design wasn’t stable enough.! ! !
