Isikhungo samandla adonsela phansi - izinkinga nezixazululo

1. Thola izixhumanisi zesikhungo sokudonsa phansi kwento njengoba kuboniswe esithombeni esingezansi.

Isixazululo:

Hlukanisa into ibe izingxenye ezintathu.

Indawo yengxenye 1 (A ₁ ) = (2)(6) = 12 cm ²

Iphuzu eliphakathi lilele ku-x axis (x ₁ ) = 1/2 (2) = 1 cm

Iphuzu eliphakathi lilele ku-axis ka-y (y ₁ ) = 1/2 (6) = 3 cm

Indawo yengxenye 2 (A ₂ ) = (4)(2) = 8 cm ²

Iphuzu eliphakathi lilele ku-x axis (x ₂ ) = 2 + (1/2)(4) = 2 + 2 = 4 cm

Iphuzu eliphakathi lilele ku-axis ka-y (y ₂ ) = 2 + (1/2)(2) = 2 + 1 = 3 cm

Indawo yengxenye 3 (A ₃ ) = (2)(6) = 12

Iphuzu eliphakathi lilele ku-x axis (x ₃ ) = 2 + 4 + (1/2)(2) = 2 + 4 + 1 = 7 cm

Iphuzu eliphakathi lilele ku-axis ka-y (y ₃ ) = 1/2 (6) = 3 cm

Ukuhlanganiswa kwesikhungo sokudonsa phansi ku-x axis:

I-Coordinate yesikhungo sokudonsa phansi ku-y axis:

I-coordinate yesikhungo sokudonsa phansi kwento iku-x axis kanye ne-y axis (x , y) = (4, 3)

2. Thola izixhumanisi zesikhungo sokudonsa phansi kwento, mayelana ne-axis x.

Solutions

Hlukanisa into ibe izingxenye ezintathu, u-A, u-B, u-C, no-D.

Bala indawo yengxenye ngayinye:

A _A = ½ (isisekelo)(ukuphakama) = ½ (1.5)(3) = (1.5)(1.5) = 2.25

A _B = (ubude)(ububanzi) = (4.5-1.5)(1) = (3)(1) = 3

A _C = ½ (isisekelo)(ukuphakama) = ½ (6-4.5)(3) = (1.5)(1.5) = 2.25

A _D = ½ (isisekelo)(ukuphakama) = ½ (4.5-1.5)(6-3) = ½ (3)(3) = (1.5)(3) = 4.5

y_A = 1/3 (3) = 1

y _B = 1/2 (1) = 0,5

y _C = 1/3 (3) = 1

y _D = 3 + (1/3)(6-3) = 3 + (1/3)(3) = 3 + 1 = 4

I-Coordinate yesikhungo sokudonsa phansi ku-y axis:

I-coordinate yesikhungo sokudonsa phansi mayelana ne-x axis ingu-2 cm.

3. Thola izixhumanisi zesikhungo sokudonsa phansi kwento, njengoba kuboniswe esithombeni.

Isixazululo:

Hlukanisa into ibe izingxenye ezine, u-A, u-B, u-C, no-D.

Bala indawo yengxenye ngayinye.

A _A = (ubude)(ububanzi) = (4)(3) = 12

A _B = ½ (isisekelo)(ukuphakama) = ½ (6-4)(3) = ½ (2)(3) = (1)(3) = 3

A _C = ½ (isisekelo)(ukuphakama) = ½ (8-6)(3) = ½ (2)(3) = (1)(3) = 3

A_D = (ubude)(ububanzi) = (8)(6-3) = (8)(3) = 24

y _A = 1/2 (3) = 1.5

y _B = 3 – (1/3)(3) = 3 – 1 = 2

y _C = 3 – (1/3)(3) = 3 – 1 = 2

y _D = 3 + (1/2)(6-3) = 3 + (1/2)(3) = 3 + 1.5 = 4.5

x _A = 1/2 (4) = 2

x _B = 4 + (1/2)(6-4) = 4 + (1/2)(2) = 4 + 1 = 5

x _C = 6 + (1/2)(8-6) = 6 + (1/2)(2) = 6 + 1 = 7

x _D = 1/2 (8) = 4

Ukuhlanganiswa kwesikhungo sokudonsa phansi ku-x axis:

I-Coordinate yesikhungo sokudonsa phansi ku-y axis:

1. Iyini isikhungo samandla adonsela phansi (i-COG) sento?
   • Impendulo: Isikhungo samandla adonsela phansi yindawo entweni lapho isisindo sento singabhekwa njengesisebenzayo. Yindawo emaphakathi yesisindo sento.
2. I-COG ihluke kanjani esikhungweni sesisindo?
   • Impendulo: Nakuba kokubili i-COG kanye nendawo ephakathi kwesisindo kubhekisela endaweni evamile yesisindo kanye nesisindo ngokulandelana, kungahluka uma insimu yamandla adonsela phansi esebenza entweni ingalingani. Kodwa-ke, ezimweni eziningi ezingokoqobo eMhlabeni, ziyafana ngempela.
3. Kungani ukuqonda i-COG kubalulekile ekwakhiweni kwezimoto?
   • Impendulo: Indawo ye-COG ithinta ukuzinza kwemoto. I-COG ephansi ingenza imoto ingabi namathuba amaningi okuguqa futhi ngokuvamile izinze kakhudlwana, ikakhulukazi ngesikhathi sokujika noma ukujika okungazelelwe.
4. Ukusabalalisa isisindo ngendlela ehlukile emotweni noma esakhiweni kuthinta kanjani isikhungo sayo samandla adonsela phansi?
   • Impendulo: Ukwengeza isisindo phezulu kwesakhiwo noma imoto kuzokwandisa i-COG yayo, okwenza ingabi namandla okuzinza. Ngokuphambene nalokho, ukwengeza isisindo phansi noma phansi kunganciphisa i-COG, kuthuthukise ukuzinza.
5. Uma into ilenga ngokukhululekile endaweni ethile, i-COG yayo izohlala kuphi?
   • Impendulo: I-COG yento elengayo izolala ngqo ngaphansi kwendawo yokumiswa, izivumelanise ngokuqondile nendawo yokumiswa ngenxa yamandla adonsela phansi.
6. Ingabe isikhungo samandla adonsela phansi sento singaba ngaphandle kwemingcele yezinto ezibonakalayo?
   • Impendulo: Yebo, i-COG ingatholakala ngaphandle kwezinto zangempela zento. Isibonelo esivamile indandatho noma isilinda esingenalutho; i-COG yayo iphakathi nendawo, indawo engenazo izinto.
7. Kungani abantu abahamba ngentambo eqinile bevame ukusebenzisa izingodo ezinde?
   • Impendulo: Isigxobo eside sandisa ububanzi obusebenzayo besisekelo sazo futhi sehlisa i-COG yazo. Zombili lezi ziphumo zithuthukisa ukuzinza kwazo kanye nokulinganisela kwazo ngenkathi zihamba ngentambo eqinile.
8. Ukuma nokusatshalaliswa kwesisindo entweni kuyithinta kanjani i-COG yayo?
   • Impendulo: I-COG izohlala ithambekela ezindaweni zento enobunzima obukhulu. Isibonelo, entweni lapho kunobunzima obuningi khona kolunye uhlangothi, i-COG izoba seduze naleyo nhloso.
9. Ungayithola kanjani ngokuhlola i-COG yento eyisicaba, engamile ngendlela engavamile, njengokusikwa kwekhadibhodi?
   • Impendulo: Enye indlela ukulengisa into ngephuzu bese udweba umugqa oqondile uye phansi usuka endaweni yokumiswa. Bese, lenza into isuke kwenye indawo bese udweba omunye umugqa oqondile. Iphuzu lapho le migqa ihlangana khona yi-COG.
10. Ku-biomechanics yabantu, kungani i-COG ibalulekile?

• Impendulo: Ukuqonda i-COG kubantu kubalulekile emisebenzini efana nokuhamba, ukugijima, nokugxuma. Kuthinta ibhalansi yethu, ukuzinza, kanye nendlela yokunyakaza. I-COG yomuntu ivame ukutholakala endaweni yenkaba, kodwa lokhu kungashintsha ngokuma komzimba kanye nokunyakaza.
