Voliyumu ya yamphamvu ndi

Ntchito mosiyanasiyana zojambula ndi ankachita mu mwamtheradi m'magulu onse a chuma, malonda ndi zina zotero. Ndicho chifukwa chake phunziro ili kotero bwinobwino anaphunzira maphunziro kusukulu. Koma si tonse bwino katswiri sayansi chidwi, kotero tcheru chanu akuitanidwa kumbukirani kuti yamphamvu ndi mmene kuwerengera buku lake? Ndiko kuti, pamaso mudzapeza chimene ndi buku la yamphamvu, ndi kofunika kumvetsa zimene zimakwana anali. A yamphamvu - ndi volumetric chithunzi, wopangidwa mwa zinthu zotsatirazi: ziwiri mabwalo yomweyi zofanana (mabwalo malo ofanana) ndi kupanga yamphamvu polumikiza mabwalo izi. Koma pali chikhalidwe chimodzi - yamphamvu ndi olamulira zace ayenera kukhala perpendicular ku mabwalo onse, ndiko kuti, bwalo lina kwenikweni galasi chifaniziro cha ena.

Ife anafotokoza zophweka kwambiri chitsanzo - ufulu zozungulira yamphamvu. Koma mu moyo tikhoza kukumana osati okhawo, chifukwa zosiyanasiyana awo kwambiri kotero kuti pofotokoza iwo onse kuli kovuta. Koma sikuti tidzapita ndi kuyang'ana yamphamvu yosavuta ambiri. Kotero, tsopano timadziwa kuti yamphamvu, ndi zosatheka kuwerengetsa buku ake. Ndipo kodi ndalama? M'mawu ena, mungachite fanizo pang'ono - izo ndi mphamvu choyambirira cha chotengeracho. Kuyambira tanthauzo limeneli, zikuonekeratu kuti khalidwe sitingakhoze kukhala wangwiro kuphwa mawonekedwe, ndi atatu azithunzi omwe tikunena, ndipo Kojima yamphamvu.

Tsopano tiyeni kusuntha pang'ono kwa kanjedza ndi kuwerengetsera. Kupeza zimene ndi buku la yamphamvu zofunikira kugwiritsa ntchito chilinganizo onse odziwika, umene kuchita masamu: V = πr² H

Tsopano tiyeni tione mfundo zonse za njira:

V - Cylinder buku;

π - PI;

r Mukhoza - ndi utali wozungulira bwalo;

H - kutalika kwa yamphamvu ya.

Ndi buku la yamphamvu, ife asanaganize ndi circumference wa utali wozungulira wa bwino ndiponso kuti ndi nambala ku Pihahiroti ndi kutalika kwa yamphamvu ya?

Ku Pihahiroti - nthawi zonse kusonyeza chiŵerengero cha circumference kuti kutalika kwa m'mimba mwake ake. Iwo ankakhulupirira kuti ndi numerically wofanana 3,14. Ngakhale kwenikweni nambala iyi pamene inteja gawo ndi zankhaninkhani, 10 zizindikiro (kwa anapezazo mu 2011)! Koma kwa mayiko, ife ntchito kukula wamba, chifukwa sitifunanso kuwerengetsera mkulu-mwatsatanetsatane. Ngakhale Mwachitsanzo, mu malo ntchito pazipita zotheka nambala ya zilembo pambuyo mfundo decimal!

Cylinder kutalika - ndi mtunda perpendicular pakati pa ndege ake awiri, kwa ife - mabwalo. The okwera ndi jenereta ya yamphamvu ya. Ndipo chidwi kwambiri ndi kufunika izi ndi chimodzimodzi mu kutalika kwa yamphamvu conjugated zozungulira.

Tsopano inu mukudziwa zonse zosintha mu aone kuti pali, pali funso ngati ndipo n'chifukwa chiyani anatero? Tiyeni kufotokoza chitsanzo kwa bokosi. Aliyense akudziwa kuti buku lake ndi wofanana ndi mankhwala miyeso ake atatu: m'litali, m'lifupi, ndi msinkhu. Mbali m'munsi mwa chithunzi ndi mankhwala a kutalika kwa m'lifupi, i.e., Iwo analandira kuti voliyumu ndi mankhwala a m'munsi lalikulu ndi kutalika. Tsopano tibwererenso ku yamphamvu wathu, onse ofanana: V = Shii, kumene S - ndi yamphamvu m'munsi dera, kuyambira m'munsi ife zungulizani, ndi m'dera lozungulira ndi: S = πr².

Tsopano ife tikudziwa mmene kuwerengera buku la yamphamvu, koma angatipatse? ndi angagwiritsire ntchito Zomwe mungaphunzire chiyani? Tsiku ndi tsiku kudziwa izi sanamvere Mwachitsanzo, zosatheka kuwerengetsa mmene madzi ambiri chidzadzaza chimodzi kapena chimzake cylindrical chinthu monga adzayenerera zipangizo lotayirira makamaka ndi cylindrical chidebe. Ngakhale sitingathe kuchita popanda izo. Koma makampani popanda kudziwa ngati n'zosatheka kuchita. Mwachitsanzo, kupanga mapaipi zolinga zosiyanasiyana kuwerengetsa kuchuluka kwa madzi kapena mpweya, iwo ndidzadutsa pa botolo la nthawi, etc.
