Puʻe puaʻa hiwa ma ke ano maoli

paa moku'āina puʻe - ia mea kuhikuhi i ka mua e uhau ana o ka enemi. Aie i ka mea i loaʻa mea he manaʻo koikoi o nā puaʻa hiwa, he mea hiki ole ke lawe mai i kekahi mau papahana ma ka rula. Interestingly, ka mea kahiko, ma ka mea ku ole i loaa keia waiwai, ka hana nani hale. Pyramids, a nui no hoi na kia hoʻomanaʻo i ka kuhikuhipuʻuone - kēia mau mea a pau i ka hopena o ka hana i ka pili ana nani masterpieces. E noonoo oe i ka puʻe pili i ka puaʻa hiwa.

Loaʻa nō i loko o ia mau manawa o ka manaʻo koikoi o nā puaʻa hiwa haʻilula hoʻolako:

P = F / S,

'o ia hoʻi ka manehu o ka luna o ke kumuhana o ka puʻe.

It E e kaulana ia ma ka mea, ke manaʻo koikoi ikaika o ke kino, he manawa maikaʻi a me ka mea i pololei ia i loko o nāʻaoʻao. Eia hana Newton ka mua kānāwai - i ka mana o ka hana like i ka ikaika o ka e kū'ē'ē mai. Pili i ke ola - ka'aloʻahiʻa ka lawe 'ana ma ke kaupaonaʻana o ka hale, ka mea, e ia i ka ia no ka lalo papa a me ka hookumuia ana mai. Nolaila, akamai, e uhau ana mau manao Will i ke kumu o ka hale. O ka holo ana, keia i ka ho omaulia kikowaena 'ē aʻe (makani mana -. Mai o ka hale, groundwater, hawewe hana, a pela aku).

No ke aha la au e pono ai kekahi kanaka, e lūlū aku i kou kaumaha ma luna o kaʻili kai nui? A laila manaʻo o ke kuikele a me ka pahi. Ua loaʻa he pahikakiwi oi loa, no ka maikaʻi anal ioeaie. Ano, e hoomanao iaoeo a me ka Track-type nā kaʻa kauō. Skiers mai i hāʻule i loko o ka hau, a me nā kaʻa kauō i maikai keʻa ma na Swamp, e like me ka mea, i ka nui hui 'āpana - a hiki i ka uuku imbeddability. Kēia SafeSearch ke kumu o haʻilula nui puʻe puaʻa hiwa - a me ka ia mana, akā,ʻokoʻa i nā wahi, me ka manaʻo koikoi e e okoa. He inversely hapaʻauhau i ka huinahalike. Ie i ka nui o ka wahi, ka mea i oi aku i ka'aloʻahiʻa. A Hope versa.

Ano hoʻi i ka poʻe e uhau ana. No ke aha la i ka mea, puʻe - he nui headache? A pau i ka mea i loko o ka ia wahi. Ma hope o nā mea a pau, i ka mau nō nā, no laila ka mea, o ka paʻakikī. Manaʻo kaumaha pōhaku puna slabs-ano. O ke ala, i ko makou manawa, loaʻa nō i ka hailona o ka ikaika, Lightweight mea. Akā, ia mea i nā mea a pau maʻalahi. Kekahi e kukulu pāhana ua oaeuiinoe ka puka waiwai. A ina ke kumu kuai o ia iā Naha Pōhaku, nā mea kiʻekiʻe, a me ke kukulu kāki koho e e nui. E like me ka hopena, he Customer 'aʻole e huki i ka Waiwai a me ka papahana, e uku aku i ka lōʻihi manawa. Akā, ua'ōlelo mai ua luna, i na lunakahiko i hoʻohana i ka puʻe o ka puaʻa hiwa i loko o lākou ka lokomaikaʻiʻia mai.

I ia mau lā, no? Ieoaeunoaa lako e aho kaupalena i ka likeʻole ma, a me ka mea. Ma hope o nā mea a pau,ʻaʻole i ka hoʻouku hana ua, a me ka pōhaku i kālaiʻia e ka lima. pōhaku puna a papa wiliʻai i kekahi i kikokiko i huiiaʻi me ka lua hehee wale. Ua ua ia e hoʻohana kahi o ka hoʻopili i ka'aloʻahiʻa puaʻa hiwa. Ka mea o ia ka mea nui o ka manaʻo koikoi, ka mea i oi aku ke koi ikaika o ka pono hana. Akā, ma ka kekahi lima, keia mea he nui frictional pūʻali koa. A ka mea, uaʻikeʻia, hiki e he nui like. E like me ka hopena, ua loaʻa i ka lako e ia i pono, na mea a pau hoomaha iho la i ka ikaika o ka umekaumaha a me ka frictional ikaika.

Ano, i noonoo ai i ka puʻe i ka huakaʻi ma mawah pehea - 300000 kPa !!! Ma ka puʻe o ka hana kūikawā crawler kaʻa kauō - 20 kPa. Loa he hoihoi 'wahi, ka mea, mehe mea, ke kaumaha piholo maila kaʻa kauō, i ka mea kŘpa a haʻahaʻa puʻe ma ka honua. Ua apono 'ia e neʻe puni ka iaʻi, a Marshland ma muli o ka lehulehu Track. Inā mākou e'ōlelo aku e pili ana i ka luna-i oleloia kū'ē, ka mea hiki ia i nāʻano, a ua haawiia e:

F = μ × N, [H]

kahi F - frictional ikaika [N]

μ - kū'ē kaʻi lau waiwai

N - maʻamau naoh [H].

I ka mana o ka puʻe i hiki ke ike, ua nā maikaʻi a me ka io nui. Nature i hakuloli a hiki i keia kŰia. People, mai ka ingeniously na mea kūkulu hoʻoneʻe i ka hana mea hou i hana muaʻole o hou mea a me nā 'ike loea. Oia ka kŰia ma ka maoli a me ka ua ia e helu pu ia me.
