Kumanikidzwa kwezvinhu zvakasimba - matambudziko nemhinduro

Kumanikidzwa kwezvinhu zvakasimba - matambudziko nemhinduro

1. Huremu nehukuru hwemabhuroko mana ari pazasi zvakafanana. Ndeipi dhisiki diki inoiswa nebhuroko pasi?

mhinduro

P = F / A

Zvichibva pafomura iyi zvakagumiswa kuti kumanikidzwa (P) kwakanangana nechisimba (F) uye kwakaenzana nepamusoro penzvimbo (A).

Simba guru, kumanikidzwa kukuru. Nzvimbo yepamusoro yakakura, kumanikidzwa kudiki.

Zvichibva pamufananidzo, nzvimbo yakakura kwazvo inosangana nepasi ichinhu III, saka kumanikidzwa kwechinhu III pasi ndiko kudiki diki.

2. Kana huremu hwematriangle mana ari pazasi hwakafanana, kumanikidzwa kukuru pasi kunoratidzwa nemufananidzo …

mhinduro

P = F / A = w / A

P = kumanikidzwa , F = simba , w = huremu , A = nzvimbo yepamusoro

Zvichibva pafomura iyi zvakagumiswa kuti kumanikidzwa (P) kwakanangana nechisimba (F) uye kwakaenzana nepamusoro penzvimbo (A).

Simba guru, kumanikidzwa kukuru . Nzvimbo yepamusoro yakakura, kumanikidzwa kudiki.

Nzvimbo diki pane dzose ndiyo ine kumanikidzwa kukuru.

3. Kumanikidzwa kukuru kunoratidzwa nemufananidzo …

mhinduro

P = F / A = w / A

P = kumanikidzwa , F = simba , w = huremu , A = nzvimbo yepamusoro

Zvichibva pafomura iyi zvakagumiswa kuti kumanikidzwa (P) kwakanangana nechisimba (F) uye kwakaenzana nepamusoro penzvimbo (A).

Simba guru, kumanikidzwa kukuru . Nzvimbo yepamusoro yakakura, kumanikidzwa kudiki.

Nzvimbo diki pane dzose ndiyo ine kumanikidzwa kukuru.

4. Simba re500 Newton rinoshanda pamusoro pe 2.5 m ^2. Tsvaga kumanikidzwa e.

Zvinozivikanwa:

Simba (F) = 500 Newton

Nzvimbo yepamusoro (A) = 2.5 m ²

Kudiwa: Kumanikidzwa (P)

Solution:

Kumanikidzwa (P):

P = F / A

P = 500 / 2.5

P = 200 N/m ²

P = 200 Pascal

5. Huremu hwebhokisi = 75 kg uye kumhanyisa nekuda kwegiravhiti (g) = 10 m/s ^2. Sarudza kumanikidzwa kuri pasi.

Zvinozivikanwa:

Huremu (m) = 75 kg

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Huremu (w) = mg = (75 kg)(10 m/s ² ) = 750 kg m/s ² = 750 Newtons

Nzvimbo yepamusoro (A) = mamita matanhatu x mamita mashanu = 30 m ²

Zviri kudiwa: Kumanikidzwa pasi

Solution:

P = F/A = w/A = 750/30 = 25 N/m ²

6. Huremu hwebhokisi hunosvika 24 kg. Kukurumidza kwesimba nekuda kwegiravhiti i10 m/s ² . Tsvaga kumanikidzwa kuri pasi.

Zvinozivikanwa:

Huremu (m) = 24 kg

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Huremu (w) = mg = (24 kg)(10 m/s ² ) = 240 kg m/s ² = 240 Newtons

Nzvimbo yepamusoro (A) = 1 mx 0.4 m = 0.4 m ²

Zviri Kudiwa: Kumanikidzwa pasi

Solution:

P = F / A = w / A

P = kumanikidzwa , F = simba , w = huremu , A = nzvimbo yepamusoro

Kumanikidzwa pasi:

P = 240 N / 0.4 m ² = 600 N/m ²

1. Chii chinonzi kumanikidzwa kana tichitarisa zvinhu zvakasimba?
   • mhinduro: Kumanikidzwa kunotsanangurwa sesimba rinoshandiswa pachikamu chimwe nechimwe. Kana richishandiswa pazvinhu zvakasimba, rinoreva simba rinoshandiswa nechinhu chakasimba pane chimwe chinhu chakakamurwa nenzvimbo yekubata.
2. Nzvimbo yekubata inokanganisa sei kumanikidzwa kunoitwa nechinhu chakasimba?
   • mhinduro: Kumanikidzwa kunoitwa nechinhu chakasimba kunoenderana nenzvimbo yakabatwa. Kana simba rikaramba riripo, kuwedzera nzvimbo yakabatwa kunoderedza kumanikidzwa, uye kuderedza nzvimbo yakabatwa kunowedzera kumanikidzwa.
3. Sei zvinhu zvakapinza zvakaita setsono nezvipikiri zvichipinda nyore nyore pamusoro?
   • mhinduro: Zvinhu zvakapinza zvine nzvimbo diki kwazvo yekubata. Kana simba rikashanda, izvi zvinoita kuti pave nekumanikidzwa kwakanyanya pamucheto, zvichiita kuti zvive nyore kupinda mune zvimwe zvinhu.
4. Shangu dzechando dzinodzivirira sei munhu kuti asanyure zvakanyanya muchando?
   • mhinduro: Shangu dzechando dzinoparadzira huremu hwemunhu panzvimbo yakakura, zvichideredza kumanikidzwa kwechando. Izvi zvinodzivirira kana kuderedza kunyura.
5. Sei marori anorema aine matai makuru uye akafara kupfuura mota diki?
   • mhinduro: Matayi makuru uye akafara anoparadzira huremu hwerori hwakanyanya pamusoro penzvimbo yakakura, zvichideredza kumanikidzwa kuripo mumugwagwa. Izvi zvinobatsira kudzivirira kukuvara kwemugwagwa uye kupa simba riri nani.
6. Kumanikidzwa kunoenderana sei nekudzika kwechinhu chakasimba?
   • mhinduro: Kusiyana nemvura, kumanikidzwa kwezvinhu zvakasimba hakugari kuchikwira nekudzika nenzira inofungidzirwa nekuda kwegiravhiti chete. Kumanikidzwa pakadzika kwechinhu chakasimba kunoenderana nehuremu hwacho pamusoro penzvimbo iyoyo uye hunhu hwechimiro uye hwezvinhu zvechinhu chakasimba.
7. Sei bhuku rinorema risingakuvadzi tafura asi chinhu chakapinza chisina huremu hwakawanda chichikuvadza?
   • mhinduro: Kumanikidzwa kunoitwa nechinhu kunoenderana nehuremu hwacho nenzvimbo iyo huremu ihwohwo hunoparadzirwa. Bhuku rinorema rinoparadzira huremu hwaro panzvimbo yakakura, zvichikonzera kumanikidzwa kwakaderera. Chinhu chakanongedza, kunyangwe chiri chiedza, chinoisa simba racho panzvimbo diki, zvichikonzera kumanikidzwa kwakakwira, izvo zvinogona kukuvadza tafura.
8. Kupararira kwedzvinyiriro muzvinhu zvakasimba kunokanganisa sei nheyo dzekuvaka?
   • mhinduro: Nheyo dzekuvaka dzinoparadzira huremu hwechivako panzvimbo yakakura, zvichideredza kumanikidzwa kuri pasi. Kugoverwa kwakakodzera kwekumanikidzwa kunoita kuti chivako chisanyure kana kutsveyama nekuda kwekugadzika kusina kuenzana.
9. Sei shangu refu dzichiwanzosiya maburi akapfava?
   • mhinduro: Shangu refu dzinoisa huremu hwemunhu akapfeka panzvimbo diki, zvichiita kuti apindwe nesimba zvakanyanya panzvimbo yaanogunzva. Panzvimbo dzakapfava, kumanikidzwa uku kunogona kukonzera mavanga kana mavanga.
10. Kana ukadzvanya ruoko rwako pamadziro, sei rusinganyure mumadziro sezvarungaita nechinhu chakapfava?

• mhinduro: Hunhu hwemadziro hunodzivirira kushanduka, kunyangwe kana ruoko rwako rwashandiswa. Kunyange zvazvo ruoko rwako ruchimanikidza madziro, madziro acho akasimba uye akaomarara zvakakwana kuti adzivirire kumanikidzwa, zvichidzivirira ruoko rwako kuti rusanyure.
