Structures & materials
Bilong wanem ol bris i sanap na ol taua i no pundaun
Ol structure (ol samting ol i wokim i sanap, olsem bris na taua) i karim hevi: ol bris, taua, rup na frem. Sep yu makim na samting yu yusim long wokim em i makim sapos structure i sanap strong o i bagarap.
Em i gutpela long husat
Ol pikinini i save wokim ol taua na bris, na olgeta husat i tingting bilong wanem sampela sep i strong moa.
Wanem samting yu bai lainim
- Wanem samting em hevi (load), tension (strong i pulim samting na mekim em i longpela) na compression (strong i presim samting na mekim em i sotpela)
- Bilong wanem ol sep i gat tripela kona (triangle) i mekim ol structure i strong na i no bend
- Olsem wanem ol kain samting i save mekim: i no bend o i bend isi, i strong o i bruk isi
- Olsem wanem long painim hap i no strong na mekim em i strong moa
Sampela kain experiment
-
Wokim wanpela bris long ol bim na putim hevi antap long en inap long em i bend tumas.
-
Skelim wanpela frem i gat foapela kona (square) na wanpela frem i gat tripela kona (triangle), aninit long wankain hevi.
-
Wokim wankain taua long narapela narapela kain samting.
Ol samting yu ken wokim
-
Wanpela bris i gat planti tripela kona (truss bridge)
-
Wanpela taua i sanap strong long win
-
Han bilong wanpela kren
Ol dispela eksampel i soim kain wok i stap long dispela hap. Ol lesen ol i putim ples klia inap i no wankain olgeta.
Wanem samting simulesen i lusim
- Simulesen i stori long ol kain samting long sampela isi pasin tasol; ol tru samting i gat ol liklik bagarap, na ol i senis taim ol i lapun na long san na ren.
- Ol ansa i soim olsem wanem wanpela disain i mekim insait long model. Ol tru bilding i nidim ol injinia husat i skul pinis long dispela wok, na ol i mas chekim sefti bilong ol.
Olgeta simulesen i lusim sampela samting bilong tru laip. Long save olsem wanem em i mekim olsem, em i wanpela hap bilong lainim wok injinia.
Ol sabjek bilong skul i join wantaim
Physics, matematik (geometry), architecture (disain bilong haus na bilding), art (droim na pen)
Join wantaim ol narapela hap
Structures i sanap long mechanics, na ol i holim olgeta samting, long ol robot i go inap long ol bilding.
Gutpela long save
Wanpela sep i gat tripela kona (triangle) i no inap senisim sep bilong en, sapos wanpela sait bilong en i no kamap longpela moa o sotpela moa. Olsem na ol kren, rup na frem bilong wilwil i pulap long ol triangle.

Kinematics
Olsem wanem ol hap masin i wok wantaim (mechanism) i muv: ol gia, ol stik i join wantaim (link) na ol cam (wil i gat sep i no raun)
