Truss Bridge

In room7 we are learning about bridges. Katherine and I did a Truss bridge. We made our bridge out of string, cardboard,newspaper and lots and lots of cello-tape. To make our bridge we firstly made the frame and the hardest part was to get it even. After that we put two bits of newspaper(one on the top one on the bottom) across to connects one frame to another. Next we put the string on to make a triangle shape. The last part we did was putting the cardboard on for the road.

Turss Bridge

Did you know that there are five different types of a Truss bridge. Here they are.

• Warren Truss Bow String


• King Post Crver Chord

Most Truss Bridges have triangles to support the beams and icreas the rigidity.

The Truss bridge got its name from the peson called Warren Truss. He designed the first ever Truss bridge.

Maths

I am learning to solve addition problems by going back through the tens.
34-7=47 (34-4+30-3=47)
65-8=57 (65-5=60-3=57)
72-9=63 (72-2=70-7=63
83-8=75 (83-3=80-5=75)
132-7=125 (132-2=130-5=125)
271-8=263 (271-1=270-7=263)
393-6=387 (393-3=390-3=387)

I solved these problems by going back to a tidy ten.Then I took away the one that I had left.

Solar Ovens
