Inkinga yesisindo iphazamisa wonke amantombazane. Ngakho ukucabanga kwaleyo nsizwa kuhlelwe, ukuthi akasoze aneliswa yisisindo sakhe. Kuhlale kubonakala sengathi isisindo noma ngokweqile, noma akwanele, futhi uthole intombazane enjalo eyingqayizivele engayibheka ukuphakama kwayo nesisindo esihle - akunakwenzeka. Futhi uma isisindo singasethinteka, khona-ke ukukhula - yebo, cha. Futhi ngalesi simo izicathulo kuphela ezinezithende eziphakeme zizosiza. Ngakho-ke, namuhla sizogxila ezindleleni ezikhona, ukuthi singakanani isisindo esihle sentombazane.
Iyini isisindo esihle sentombazane?
Uma ukhohlwa okwesikhashana lokho esikutsheliwe kusuka esikrinini se-TV namakhasi omagazini abaluhlaza, ngomuntu othathwe "ngezindinganiso zokubukeka", mayelana nemibono yezinambuzane ezihlinzeka ngamapulasitiki nabanye abantu abathakazelayo, singasho ukuthi isisindo esihle kakhulu intombazane nguye isisindo semvelo. Ake sichaze lokhu ngale ndlela elandelayo: imvelo, ukunikeza umuntu ngalezi zindlela noma enye idatha yomzimba, iqondiswa yimithetho nemigomo yayo. Ngesizathu esithile, sakha abantu abanezilinganiso ezahlukene zokukhula nesisindo somzimba. Uma izinkambiso ezikhona "ezilungile" zifanelekile kubo bonke abantu, khona-ke wonke umuntu wayezozalwa enesisindo nesisindo esifanayo, futhi angakhula ngokuvumelana namathebulethi abhalwe ezincwadini zokufunda ngezingane. Kodwa lapho ingane ikhula, akenzeki nanoma ubani ukuthi kufanele ivinjelwe ekudleni ukuze ivumelane nedatha ye-tabular. Ngakho-ke kungani amantombazane amancane engavumi ukuthi isisindo somzimba esithile sinikezwa ngesizathu esithile, hhayi nje? Okungenani, kufanele bacabange ngalokhu.
Futhi uma ungomkhakha wabantu abacabanga ukuthi isisindo esifanele besifazane akusilo isisindo semvelo, kodwa siyisimiso esivamile, siphakamisa ukuthi uzijwayele ngefomula ehlukene esiza ukubala isisindo esihle sentombazane nowesifazane.
Indlela eyodwa
Wonke umuntu uyazi ifomula elandelayo, isisindo esihle = ukuphakama okungaphezulu kuka-110. Kodwa kule fomula, akukho nhlobo ifakwe kuleso parameter njengeminyaka yobudala bomuntu. Futhi kule fomu elingenhla, ifomula ifaneleka kwabesifazane abaneminyaka engama-40 kuya ku-50. Uma sikhuluma ngamantombazane, okungukuthi, uma iminyaka yowesifazane isukela eminyakeni engu-20 kuya kwezingama-30, khona-ke ifomula ithatha ifomu elilandelayo, isisindo esihle = ukuphakama okungaphezulu kuka-110 nokunciphisa 10%. Futhi kulabo besifazane abangaphezu kuka-50, ifomula ibonakala kanje, isisindo esihle = ukuphakama kususa okungu-110 futhi kususa 7%. Isibonelo: ukuphakama kwentombazane ngu-165 cm. Isisindo sayo esihle (165 - 110) × 0.9 = 49.5 kg.
Indlela yesibili
Uma ukholelwa ososayensi baseMelika, isisindo esihle sentombazane singabalwa kanje: (ukwandisa okungenani 150) wande nge 0.75 bese wengeza 50.
Isibonelo: ukuphakama kwentombazane ngu-165 cm. Isisindo esihle (165 - 150) × 0.75 + 50 = 61.25 kg.
Indlela Yesihlanu
Le fomula yokubala isisindo esihle ibizwa ngokuthi i-formula ye-Lorentz. Isisindo esihle = (ukuphakama - 100) - 0,25 * (ukukhula - 150). Isibonelo: ukuphakama kwentombazane ngu-165 cm. Isisindo esihle = (165 - 100) - 0.25 * (165 - 150) = 61.25 kg.Indlela yesine
Le ndlela yokunquma isisindo esihle ibizwa ngokuthi inkomba kaKatle. Inkomba isilingana nesisindo somuntu (ngo-kilogram) esihlukaniswe isikwele sokukhula (ngamamitha).
Isibonelo: ukuphakama kwentombazane ngu-165 cm, isisindo esingu-65 kg. Inkomba yomzimba = 65 / (1.65 × 1.65) = 23.87. Kusho, isisindo sisejwayelekile.
Futhi, usebenzisa le ndlela, ungakwazi ukunquma imingcele yesimiso sesisindo intombazane. Ukuze unqume umkhawulo ophansi, udinga ukwandisa 18 ngesikwele sokuphakama ngamamitha, nangomngcele ongaphezulu we-25, wande ngesikwele sokuphakama ngamamitha.
Isibonelo: ukuphakama kwentombazane ngu-165 cm. Umkhawulo ophansi wesisindo somzimba ngu-18 × 1.65 × 1.65 = 49 kg. Umkhawulo ongaphezulu wesisindo somzimba = 25 × 1.65 × 1.65 = 68 kg.
Way Five
Ukubala isisindo esihle samantombazane, kufanele usebenzise ifomula elandelayo: ukwandisa ukuphakama ngevolumu lesifuba bese uhlukanisa nge-240. Isibonelo: ukuphakama kwentombazane ngu-165 cm, ivolumu yesifuba i-90 cm. Isisindo esihle = 165 × 90/240 = 61.9 kg.
