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)
Hap namba 01
Mechanics
Fos, muv na enerji: ol lo i stap aninit long olgeta masin
Mechanics (save long ol fos, olsem pus o pul, na long muv) i soim bilong wanem ol samting i muv, i go hariap moa, i go isi moa, o i no muv. Em i as bilong klostu olgeta masin.
Em i gutpela long husat
Olgeta husat i nupela long dispela wok: ol pikinini i laik pusim, pulim, rolim na apim ol samting, na i laik save bilong wanem ol i muv.
Wanem samting yu bai lainim
- Wanem samting em fos, na ol fos i bung wantaim olsem wanem
- Olsem wanem friction (strong i kamap taim tupela samting i rap) i save helpim, na olsem wanem em i save kamap hevi
- Olsem wanem ol lever (stik bilong apim samting), ol pulley (wil bilong rop) na ol ramp (rot i go antap isi isi) i mekim wok i isi moa
- Olsem wanem enerji i senis long wanpela kain i go long narapela kain
Sampela kain experiment
-
Larim wanpela liklik kar i ron i go daun long ol ramp i gat narapela narapela angle, na skelim spit bilong en.
-
Muvim pivot bilong lever (hap we lever i tanim long en) na painim fos i liklik tru we i inap apim wanpela hevi samting.
-
Senisim ples aninit long wanpela blok na lukim olsem wanem friction i senisim muv bilong en.
Ol samting yu ken wokim
-
Wanpela ramp wantaim liklik kar na samting bilong stopim kar
-
Wanpela lever i apim wanpela hevi samting
-
Wanpela isi sistem bilong pulley
Ol dispela eksampel i soim kain wok i stap long dispela hap. Ol lesen ol i putim ples klia inap i no wankain olgeta.
Traim wanpela liklik model
Ol dispela liklik model i ron hia stret long brausa bilong yu, na taim pes i lod pinis, ol i wok yet maski yu offline (i no nidim intanet). Ol i isi model bilong lainim, i no program bilong simulesen bilong MEKALUMI.
Toksave: pulim gia long han kais bilong tanim em long han bilong yu.
Ol gia i wok wantaim (gear train)
Senisim hamas tit i stap long wanpela wanpela gia. Lukim olsem wanem spit na strong bilong tanim (torque) i senis.
- Ratio bilong ol gia
- 1 : 2
- Spit bilong las gia
- 15 rpm · 2× isi moa
- Strong bilong tanim
- × 2
- Rot
- I tanim narapela rot long mota
Taim wanpela liklik gia i tanim wanpela bikpela gia, bikpela gia i tanim isi moa, tasol em i gat moa strong. Ol winch (masin bilong pulim rop), wilwil na klok i yusim dispela tingting.
Model: ol gia i stret olgeta, i no gat friction na ol tit i no save kalap. Spit bilong mota: 30 rpm.
Wanem samting simulesen i lusim
- Planti taim simulesen i tingim ol samting olsem ol i strong olgeta na sep bilong ol i no save senis: ol i no save krungut, bruk o bagarap long longpela yus.
- Friction na air resistance (win i pasim samting i muv) i bihainim ol isi formula; long tru laip, ol samting i paul moa.
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 (ol angle na ratio), spot
Join wantaim ol narapela hap
Mechanics em i as bilong kinematics, structures na robotics.
Gutpela long save
Ol i tok Archimedes i bin tok olsem: sapos em i gat wanpela lever i longpela inap na wanpela ples bilong sanap, orait em inap muvim Ples Graun.
