TRANSCRIPT
Bharpak, NepalGetting crops to a market is slow and difficult in the mountains
It can take over 6 hours on foot!!
Bharpak, Nepal
Engineers have designed a GRAVITY ROPEWAY to make the journey easier…
Bharpak, Nepal
Bharpak, NepalThe journey now takes 10 minutes!!
And the villagers can sell more, fresher crops
=
The whole village is prospering!!

Let’s look at another example..
Kibera slum, NairobiKibera is the largest slum in Africa
Half the residents are under 15Most live on £1 or £2 a day
Yuk!
Kibera slum, NairobiChildren would have to cross this to get to school!
Kibera slum, NairobiThis is where we need engineers!
Kibera slum, Nairobi
The final bridge!!
LET’S PLAY A GAME!
You’re going to build a bridge..
Bridge buildingThere are several types of bridges
Suspension Bridge
Arch Bridge
Truss Bridge
Cable-Stayed Bridge
Rigid Frame Bridge
Truss bridges
Why are they strong?
Truss bridgesTriangles are seen in lots of structures:
Your task..You are engineers who must build a bridge in Nicaragua
In the rainy season the river is impossible to pass
Your task…Build a truss bridge to cross a 20cm gapThe bridge must support # kg
Is the winning bridge…The one that held the most
Or that held the closest to # kg
A real one..
A community without roads does not have a way out
If we get transport we get everything else: a community centre, water, employment, post office, telephone..
What can you do..?
Maybe one day you could be an engineer?
Ask us questions!!
Tell your parents and friends about what you learnt
THANK YOU!
