Mirayiridzo yeKuedza Mutemo waHooke
Zvinangwa zvekuedza uku:
- Kuongorora hukama huripo pakati pesimba nekuwedzera kwehurefu hwechitubu
- Sarudza chinoramba chiripo chechirimo
Zvishandiso Nezvinhu: Masipiringi, huremu hwemagiramu makumi mashanu (4), tripod, ruler
Dzidziso huru:
Mutemo waHooke unoti hukuru hwesimba hunoenderana zvakananga nekuwedzera kwehurefu hwechitubu. Simba rinoshanda pachitubu rakakura, kureba kwechitubu kunowedzerawo. Chiyero chehukuru hwesimba nekuwedzera kwehurefu hwechitubu chinogara chiripo. Mutemo waHooke unoshanda kana simba risingapfuure muganho we elastic wechitubu. Mutemo waHooke wakakurudzirwa naRobert Hooke (1635-1703).
Panyaya yemasvomhu, mutemo waHooke unoratidzwa kuburikidza ne equation: k = F / Δl. Kupi: k = chitubu chisingachinji, F = simba, Δl = kuwedzera kwehurefu hwechitubu.
Chikamu chepasi rose chesimba ndiNewton, chikamu chepasi rose chehurefu imita, saka chikamu chepasi rose chenguva dzose yechirimo iNewton/mita (N/m).
Matanho Ekuyedza:
1. Unganidza tripod sezvakaratidzwa mumufananidzo.
2. Tungamira chitubu pachigadziko wobva wabatanidza huremu hwemagiramu makumi mashanu pasi pechitubu. Yera kureba kwechitubu sehurefu hwechitubu 1 (lo 50 ).
l 1 = …… Masendimita.
3. Regedza mutoro we50 gram zvakare, wozoyera kureba kwechitubu sehurefu hwechitubu 2 (l 2 ).
w = 0,5 Newton
Δl = l 2 – l 1 =………… Masendimita
k = w / Δl =………… N/cm
3. Regedza mutoro we50 gram zvakare, wozoyera kureba kwechitubu sehurefu hwechitubu 3 (l 3 ).
w = 0,5 + 0,5 = 1 Newton
Δl = l 3 – l 1 = ………… Masendimita
k = w / Δl =………… N/cm
4. Regedza mutoro we50 gram zvakare, wozoyera kureba kwechitubu sehurefu hwechitubu 4 (l 4 ).
w = 0,5 + 0,5 + 0,5 = 1,5 Newtons
Δl = l 4 – l 1 = ………… Masendimita
k = w / Δl =………… N/cm
Kuongorora Data neData:
Kune zvikamu zvitatu zvechitubu zvichienderana nemhedzisiro yechiedzo chekare. Verenga avhareji yezvikamu zvechitubu:
k = (k + k + k) : 3 = ……………… N/cm
Dhirowa girafu inoratidza hukama huripo pakati pegiravhiti (w) nekuwedzera kwehurefu hwechitubu (Δl)
Kukurukurirana:
– Hukama huripo pakati pesimba nekuwedzera kwehurefu hwechitubu? Kana simba racho rakakura, kuwedzera kwehurefu hwechitubu kuchave kukuru here, kusingachinji, kana kudiki?
– Zvimisikidzo zvechitubu zvakafanana here? Kana zvisiri, sei?
- Ndeipi avhareji yenguva yechirimo inowanikwa kuburikidza nekuyedza?
