Kodi chulucho ndi chiyani: tanthauzo, zinthu, mitundu

M'bukuli, tiwona tanthawuzo, zinthu zazikulu ndi mitundu ya imodzi mwa mawonekedwe omwe amapezeka kwambiri mumlengalenga - cone. Zomwe zaperekedwa zimatsagana ndi zojambula zofananira kuti mumvetsetse bwino.

Tanthauzo la cone

Kenako, tikambirana za mtundu wodziwika bwino wa cone - chozungulira chowongoka. Mitundu ina yotheka yachiwerengeroyo yandandalikidwa mu gawo lomaliza la kufalitsa.

kotero, chozungulira chozungulira chowongoka - Ichi ndi chithunzi chazithunzi chazithunzi zitatu zomwe zimapezedwa pozungulira makona atatu akumanja kuzungulira miyendo yake, yomwe pakadali pano idzakhala olamulira a chithunzicho. Poganizira izi, nthawi zina chulucho chotere chimatchedwa cone of Revolution.

Cone mu chithunzi pamwambapa imapezeka chifukwa cha kuzungulira kwa makona atatu oyenera Zamgululi (kapena BCD) kuzungulira mwendo CD.

Zinthu zazikulu za cone

• R ndiye utali wozungulira womwe uli cone base. Pakatikati mwa bwalo ndi mfundo D, m'mimba mwake - gawo AB.
• h (CD) - kutalika kwa chulucho, chomwe chiri mbali zonse za chiwerengerocho ndi mwendo wa makona atatu oyenera Zamgululi or BCD.
• Point C - pamwamba pa chulucho.
• l (CA, CB, CL и CM) ndi majenereta a cone; awa ndi zigawo zolumikiza pamwamba pa chulucho ndi mfundo zozungulira maziko ake.
• Chigawo cha axial cha cone ndi makona atatu a isosceles ABC, yomwe imapangidwa chifukwa cha mphambano ya cone ndi ndege yomwe imadutsa mumtunda wake.
• Pamwamba pa cone - imakhala ndi malo ake ozungulira komanso maziko ake. Mafomu owerengera , komanso cone yozungulira yoyenera imaperekedwa m'mabuku osiyana.

Pali ubale pakati pa jenereta ya kondomu, kutalika kwake ndi utali wozungulira wa maziko (malinga ndi):

l² =h² +R²

Kusanthula koloko - pamwamba pamtunda wa cone, woyikidwa mu ndege; ndi gawo lozungulira.

• ndizofanana ndi kuzungulira kwa maziko a cone (ie 2 pa R);
• α - kusesa ngodya (kapena mbali yapakati);
• l ndi gawo lozungulira.

Zindikirani: Tinapendanso zazikulu m’buku lina.

Mitundu ya cones

1. choongoka - ali ndi symmetrical maziko. Kuwonekera kwa orthogonal pamwamba pa chithunzichi pa ndege yoyambira kumagwirizana ndi pakati pa maziko awa.
2. Oblique (oblique) cone - chiwonetsero cha orthogonal cha pamwamba pa chithunzi pa maziko ake sichigwirizana ndi pakati pa maziko awa.
3. (conical layer) - gawo la cone lomwe limakhala pakati pa maziko ake ndi ndege yodula yofanana ndi maziko operekedwa.
4. chozungulira chozungulira Pansi pa chithunzicho ndi chozungulira. Palinso: elliptic, parabolic ndi hyperbolic cones.
5. equilateral cone - chulu chowongoka, jenereta yomwe ili yofanana ndi m'mimba mwake ya maziko ake.
