Mirayiridzo yekuyedza mutemo yaArchimedes
Chinangwa chekuedza kwemutemo kwaArchimedes:
- Vadzidzi vanogona kuyera huwandu nehuremu hwemvura yakabviswa nechinhu chakanyudzwa mumvura.
- Vadzidzi vanogona kuziva nekunzwisisa mutemo waArchimedes
Zvishandiso nezvinhu:
– Mudziyo wepakati nepakati (1)
– Kadhi diki (1)
– Dynamometer (1)
– Rodha (1)
- Mhepo
Matanho ekuyedza:
(Muedzo kuongorora huwandu hwemutoro)
– Isa mvura mumudziyo wepakati kusvika mvura yazara.
– Uyai nemudziyo mudiki pedyo nemudziyo wepakati nepakati.
– Isa zvishoma nezvishoma huremu mumudziyo wepakati nepakati wakazara nemvura.
– Mushure mekunge mutoro waiswa mumudziyo wepakati nepakati, mvura yakabuda. Mvura yainge yadeuka yaizodururirwa mumudziyo mudiki.
– Yera huwandu hwemvura yakadururwa. Kana ukashandisa chubhu yekuyera kana mudziyo wechikero, pane chikero pamadziro echubhu. Mutsetse unoenderana nepamusoro pemvura = huwandu hwemvura yakadururwa. Vhoriyamu (V) = …… cubic metres (m)3)
– Kana usiri kushandisa silinda yakagadzikwa, huwandu hwemvura hunogona kuonekwa uchishandisa nzira inotevera. Yera denderedzwa remudziyo. Kana denderedzwa remudziyo riri denderedzwa, verenga radius uchishandisa fomura yedenderedzwa. Kana denderedzwa remudziyo riri sikweya kana rectangle, verenga kureba nehupamhi uchishandisa denderedzwa resikweya kana denderedzwa refomura yerectangle. Nyora zvawawana pakuverenga. Radius yemudziyo (r) = …… mamita kana kureba kwemudziyo (p) = …….. mamita. Upamhi hwemudziyo (l) = …… mamita
– Pima kukwirira kwemvura uchishandisa mudziyo wekuyera. Kureba (t) = …… mamita
– Shandisa fomura yehuwandu kuverenga huwandu hwemvura yakadururwa. Fomura yehuwandu inogadziriswa kuti ienderane nechimiro chesilinda. Vhoriyamu (V) = …… cubic metres (m)3)

(Kuverenga hukuru hwesimba rinoyerera)
Verenga hukuru hwesimba rinopfungaira uchishandisa fomura yesimba rinopfungaira:
FA = g V = (1000)(9,8)(V) = (9800)(……..) = ……… Newton.
Information :
FA = simba rekudzika, = kuwanda kwemvura = 1000 kg/m3, g = kukurumidza nekuda kwegiravhiti = 9,8 m/s2.
(Edza kuongorora huremu hwemvura yakadururwa)
– Isa mvura mumudziyo wepakati kusvika mvura yazara.
- Pima huremu hwemudziyo mudiki uchishandisa chikero (m = …… makirogiramu)
– Uyai nemudziyo mudiki pedyo nemudziyo wepakati nepakati.
– Isa zvishoma nezvishoma huremu mumudziyo wepakati nepakati wakazara nemvura.
– Mushure mekunge mutoro waiswa mumudziyo wepakati nepakati, mvura yakabuda. Mvura yainge yadeuka yaizodururirwa mumudziyo mudiki.
– Yera huremu hwechirongo chidiki chine mvura yakadururwa (m' = …….kilogiramu)
– Huremu hwemvura yakadururwa = m' – m = …… makirogiramu
– Verenga huremu hwemvura yakadururwa. Shandisa avhareji yekumhanyisa simba regiravhiti = g = 9,8 m/s2.
w = (m' – m)(9,8) = ………….Newton
Mhedziso:
Pindura mibvunzo inotevera zvichibva pane zvawakaita.
– Simba rinopfungaira rakakura sei?A = ………… Newton
– Mvura yakawanda sei inodururwa? w = ………….. Newtons
– Hukuru hwesimba rinoyerera mvura hwakafanana here kana kuti hwakafanana nehuremu hwemvura yakadururwa?
Kana zvakadaro, saka waita bvunzo yako nekuverenga zvakanaka. Kana hukuru hwesimba rinoyerera hwakasiyana zvakanyanya nehuremu hwemvura yakabviswa, saka bvunzo yako nekuverenga hazvina kuitwa zvakanaka.
Hukuru hwesimba rinoyerera hwakaenzana nehuremu hwemvura yakadururwa = mutemo waArchimedes.
