Otchedwa mphindi mphamvu? Kodi kufotokoza izo?

Tiyeni tiyese kuti adzaone zomwe amatchedwa mfundo mphamvu. Mawu amenewa kawirikawiri amagwiritsidwa ntchito sayansi. Kusanthula pansi akuti zikusonyeza ntchito pa mapewa ndi Ufumuyo mphamvu yake.

Features

Kusanthula funso otchedwa mphindi mphamvu m'pofunika kutchula ndi mayunitsi a mtengo uwu. Mu dongosolo SI izo amayezedwa NM.

makokedwe

Makokedwe a mphamvu za mfundo ndi kufunika kugwirizana ndi popezera mpata ndi mphamvu. Pamoyo, anthu ntchito "ndalezo ulamuliro", ozikidwa ndendende pa gulu mfundo.

Mwachitsanzo, pofuna kukwaniritsa mamba-kugwedezeka, tiyenera kudziwa otchedwa mphindi mphamvu, ndi momwe angagwirizanitse bwino. Phewa otchedwa imeneyi pakati pa ntchito mfundo ndi chikatikati mfundo.

Mwachitsanzo, zovuta nakatsegula pakhomo, akukankha izo kwa mfundo ogwiritsa. Kumvetsa chifukwa chake zili choncho zovuta kuchita, muyenera kudziwa chimene chimatchedwa mphindi ya mphamvu za olamulira ndi.

Tiyerekeze kuti mufunika kutsegula chitseko, ndi m'lifupi mita, annexing 100 N. Kutsatira kuyenera kukhala malo atatu:

• pafupi kumadalira ndi;
• pakati;
• pa nsonga ya chinsalu cha.

Pakuti loyamba mlandu phewa ndi ziro, chotero, ntchito pa dzanja adzakhala anagwira mphamvu mtengo wa ziro.

Pakuti njira pakati pa chitseko, mphindi zizigwirizana 50 NM. Pansi kufika pakhomo tsamba adzakhala ndi phindu pazipita 100 NM.

kuwerengetsera amenewa n'zotheka kunena kuti kutayika mtunda imalipidwa ndi phindu mu khama.

phewa kumanja

Pankhani ya kutsatira mphamvu pa cham'mbali, n'zosatheka kulankhula za kudziwa mphamvu phewa monga ankaona kale. Pofuna kuchepetsa ntchito imeneyi, muyenera kugwiritsa phewa kumanja. mphamvu phewa otchedwa perpendicular kutalika kuti mulibe kuchokera chikatikati mfundo mzere wa ntchito ya mphamvu.

Pofuna kudziwa mphamvu dzanja, kuwonjezera mzere. Ndiye adatchithisira perpendicular kwa mfundo chikatikati.

Chifukwa ndi makona ndi kumathandiza kupeza ngodya zabwino bwino. Pogwiritsa ntchito malamulo a ndikuyenda n'zotheka mwa nkusani kudziwa nthawi mphamvu.

Kuganiza kuti mphamvu umagwiritsidwa ntchito pa makona a madigiri 45. Pankhaniyi, nthawi analandira 70 NM. Zimakhala zoonekeratu kuti ntchito kutsegula chitseko pa ngodya ya 0 digiri. Mphamvu zoterozo alibe zolosera umene ungamuphe gulu rotational. Pakalibe phewa lake, ena kuposa ziro, salola mphamvu zolenga makokedwe. Mukaganizira zimene amatchedwa mphindi mphamvu, tisaiwale kuti ndi vekitala kuchuluka. Pofuna kudziwa malangizo a nthawi mphamvu, ntchito ya dzanja lamanja ulamuliro. Mofananamo, kudziwa malangizo a vekitala mathamangidwe okhota.

Kodi wapadera za lamulo limeneli? Phimbani m'dzanja la kudzanja lamanja olamulira a kasinthasintha, kotero kuti malangizo a zala limagwirizana ndi malangizo a mphamvu ntchito. Pa chala choyamba kudziwa malangizo a okhota patsogolo vekitala mphamvu. Otchedwa mphindi ya mphamvu za mfundo amodzi? Khalidwe limeneli, lomwe zikugwirizana ndi ziyerekezo kwa vekitala mphamvu kamphindi olamulira zimene mawerengedwe a idzachitike.

Mfundo yaikulu ya mphamvu ndi vekitala ndilo Uwerenge mphindi onse a magulu munthu kuti achite dongosolo ndi kulemekeza mfundo yomweyi. pakati Muitane kubweretsa dongosolo lonse la asilikali.

Mu chimake ambiri, zotsatira zake pa dongosolo lililonse olimba ndi chimodzimodzi kanthu za makokedwe a dongosolo waukulu komanso vekitala wa asilikali ntchito ku malo a galimoto.

Pomaliza

Lofotokoza makokedwe a ntchito malamulo chachikulu mphamvu, amene amadziwika chisonyezo rotational. Iye akusimba mphindi inertia, okhota mathamangitsidwe, makokedwe. Pambuyo Archimedes anakhazikitsa dzanja lamanja, popanda kusinthika kulikonse ilo lakhala likugwiritsidwa ntchito pafupifupi zaka 1,900. Only mu theka lachiwiri la m'ma 17 French wasayansi P. Pierre Varignon ilo linasinthidwa ndi chifukwa mphamvu makokedwe.

Ngati ndalezo ndi mu mgwirizano, Kuyanjana pakathi pa M1 = m2. Makokedwe ndi khalidwe la mphamvu rotational kanthu. Izo zimatengera osati pa mphamvu komanso paphewa pake. Kuti unscrew nati, ntchito wrench yaitali. Zomangira mofulumira anawomba nsalu screwdriver kukhala chogwirira mokwanira yaitali.
