Kwanini tairi za gari ni nyeusi?

[Mhandisi Mzalendo]

be serious ww black colour n good absorber n radiator af white n good reflector af cku nyngne b4 ujapost inabd ujkumbushe Google kwanza

google situmii jamaa.....
anyway may be nili mix desa

 

[Mwana Ilala]

To protect against ozone and UV damage, a stabilizer molecule called a “competitive absorber” is blended with the tire polymer.

Competitive absorbers work by capturing and absorbing UV radiation and converting it to heat which is dissipated harmlessly.

All tire manufacturers use the same competitive absorber, carbon black. This is why all tires are black.

Hukawii kusema tena Ki-English Hukijui.

 

[Leembaswagger]

Link yako mwenyewe inasema hivi

[SIZE=+1] "A black body is a theoretical object that absorbs 100% of the radiation that hits it. Therefore it reflects no radiation and appears perfectly black."[/SIZE]



Sasa hapo Mkuu, ni kipi ambacho labda mimi sikielewi?

Ulisoma kipande nini?,hujaona hii "At a particular temperature the black body would emit the maximum amount of energy possible for that temperature".

 

[Nelson Kileo]

Mkuu, baiskeli ni mashine tata wala si chombo cha moto.

weka hiyo picha yenye tairi nyeupe na utuambia unatumika nchi gani..
othrwise itakua ni concept car .. not real

 

[Nelson Kileo]

Caguo lako ni lipi hapa?

​

concept tires.. tupe pic ya gari lenye tairi hizo

Kutokana na msuguano wa lami tairi ikiwa nyeupe itakua ngumu sana kupoteza joto, hivyo kupelekea kupasuka kwa haraka.

Wakati tairi nyeusi inapopata joto kutokana na msuguano ndo rahisi kwalo kulitoa nje hivyo hakuna heat rise katika tairi

Jibu lako bado si sahihi..

Rangi nyeusi ni rangi inayovuta mwanga na kuhifadhi joto ..

Rangi nyeupe ina akisi mwanga ...na haiifadhi joto kama rangi nyeusi.

Hivyo basi ni rahisi kwa Tairi nyeusi kupasuka kuliko tairi nyeupe.. au rangi nyingine.

Stil sababu uliyoutoa hapo si sawa ukizingatia elimu ya

kuakisi na kusharubu kwenye rangi.

Kwani barabara zote ni nyeusi?! Fanya ka-research kidogo tu.

Tuletee karesearch kako basi

ulichosema ndio kinyume chake. nyeusi ndio inatunza joto kuliko nyeupe.

nadhani rangi za malighafi ya tairi ni nyeusi.

Kitaalamu ikoje.

Kwanini matairi yawe rangi nyeusi na sio rangi zingine kama red, Blue 🔵 yellow 🟡 Pink 🩷 green 🍏

 

[Jipu]

“The stabilizing chemical, carbon black makes the tires black. It prevents damage from UV light, draws heat away from parts of the car that tend to get hot when driving, and makes the tires durable.” kwa msaada wa Google.

Naomba nijibiwe maana sijawahi kuona tyre lolote lenye rangi tofauti na nyeusi.

 

[KERATO MOMBAA]

Ukijibiwa nitag na mimi

Wakati wa kutengeneza tairi, huongezwa kemikali inayoitwa carbon black (aina ya unga mweusi wa kaboni). Hii hufanya:
1.Tairi kuwa imara zaidi
2.Kuongeza nguvu na uimara wake
3.Kuzuia tairi kuchakaa haraka
4.Ulinzi dhidi ya jua (UV)
Pia,
Rangi nyeusi haionyeshi uchafu haraka na inaonekana nadhifu na ya kawaida kwa magari yote.

Zamani tairi zilikuwa nyeupe au kijivu, lakini:
Hazikuwa imara sana na zilichakaa haraka

 

[Marcostilone]

Once you go black, you never go back!

Zamani miaka ya 1900 kulikuwa na matairi meupe, lakini yalikuwa yanachafuka haraka na hayakuwa na nguvu.

Ninachojua mimi rangi nyeusi inaficha uchafu, period.

 

[MAWEED]

Kaangalie formula one grandprix inayoendelea arzbeijan....
Kampuni ya ferrari tyre zao ni nyekundu kuanzia escote,spare tair zote ni red

 

[Utak]

Ukijibiwa nitag na mimi

Tairi zinapozunguka hupata joto sana.
Kwahiyo rangi nyeusi
Husaidia kusambaza joto vizuri na hupunguza hatari ya tairi kupasuka.

Hili ndilo jibu sahihi kwamba kitu cheusi kinapoteza joto kiurahisi zaidi. i.e. the black body is a good radiator of heat generated by friction between a tyre and road.

Kaka omba msamaha kwa kuudanganya uma...black colour is a good absorber of heat kama huamini vaa shati jeusi then kaa kwenye jua...ingekua rangi nyeusi ni good radiator basi mashuleni tungevaa rangi nyeusi maana ikiradiate joto na mwanga pia utakua radiated and vise versa is true....kuweka kumbukumbu sawa black colour good absorber and silver colour good radiator... Na mfano mashuleni tunavaa rangi nyeupe za...

Mpira wa tairi bado ni mweusi kama kawaida.
👉 Ile rangi nyekundu unayoona ni mistari (markings) pembeni ya tairi tu, si tairi lote.

Kuna nchi moja ya uajami huko nimeona mashndano ya magari ya formula one g prix, matairi ni damu ya mzee, je huko wanafanyaje kuhusu mambo ya joto? Au wametumia unga wa carbon red?
Naomba elimu plz
