Musimboti wePascals - matambudziko nemhinduro

1. Anozivikanwa:

Nzvimbo yeA ₁ = 10 cm ²

Nzvimbo yeA ₂ = 100 cm ²

Simba 2 (F ₂ ) = 100 Newton

Zvinodiwa: Simba 1 (F ₁ )

Solution:

P = F / A

P = kumanikidzwa , F = simba , A = nzvimbo

P₁ =F₁ / TO₁
P₂ =F₂ / TO₂

P₁ =P₂
F₁ / TO₁ =F₂ / TO₂

F ₁ / 10 cm ² = 100 N / 100 cm ²

F ₁ / 10 = 1 N

F ₁ = (10)(1 N)

F ₁ = 10 Newton

2. Kana nzvimbo yeA ₁ = 0.001 m2 ^uye nzvimbo yeA ₂ = 0.1 m2 ^, simba rekupinda rekunze F ₁ = 100 N, saka simba rekupinda rekunze F ₂?

Zvinozivikanwa:

Nzvimbo yeA ₁ = 0.001 m ²

Nzvimbo yeA ₂ = 0.1 m ²

Simba rekunze rekupinda F ₁ = 100 Newtons

Zvinodiwa : Simba rekunze rinobuda (F ₂ )

Solution:

P₁ =P₂
F₁ / TO₁ =F₂ / TO₂

100 N / 0.001 m2 ⁼ F 2 _/ 0.1 ^m2

100 N / 0.001 = F ₂ / 0.1

100,000 N = F ₂ / 0.1

F ₂ = (0.1)(100,000 N)

F ₂ = 10,000 N

3. Kurema kwemota = 16,000 N. Chii chinonzi simba rekunze rekuisa F…

Zvinozivikanwa:

Kurema kwemota ( w) = 16,000 N

Nzvimbo yeB (A _B ) = 4000 cm ² = 4000 / 10,000 m ² = 4 / 10 m ² = 0.4 m ²

Nzvimbo yeA (A _A ) = 50 cm ² = 50 / 10,000 m ² = 0.005 m ²

Aidiwa: Force F

Solution:

F / A _A = w / A _B

F / 0.005 m ² = 16,000 N / 0.4 m ²

F / 0.005 = 16,000 N / 0.4

F / 0.005 = 40,000 N

F = (40,000 N)(0.005)

F = 200 Newton

4.

Nzvimbo yeA i60 cm ² uye nzvimbo yeB i4,200 cm ² , tsvaga simba rekunze reF.

Zvinozivikanwa:

Nzvimbo yeA (A _A ) = 60 cm ²

Nzvimbo yeB (A _B ) = 4200 cm ²

Huremu w (w) = 3500 Newton

Zvinodiwa: F ₁

Solution:

Simba raF rakaverengwa uchishandisa equation yemutemo waPascal :

F ₁ / A ₁ = F ₂ / A ₂

F ₁ / 60 cm ² = 3500 N / 4200 cm ²

F ₁ / 60 = 35 N / 42

F ₁ = (60)(35) / 42

F ₁ = 2100 / 42

F ₁ = 50 Newton

5. Chinosimudza hydraulic chine chikamu chikuru chemuchinjikwa nechikamu chidiki chemuchinjikwa. Nzvimbo yakakura yemuchinjikwa inopfuura nzvimbo diki yemuchinjikwa ka20. Kana pachikamu chidiki chemuchinjikwa pakapihwa simba rekupinda re25 N, saka sarudza simba rekuburitsa.

Zvinozivikanwa:

Nzvimbo diki yemuchinjikwa (A ₁ ) = A

Nzvimbo yakakura ine zvikamu zvakasiyana (A ₂ ) = 20A

Simba rekuisa (F ₁ ) = 25 N

Zvinodiwa: Simba rekuburitsa (F ₂ )

Solution:

1. Chii chinonzi Nheyo yaPascal?
   • mhinduro: Pascal's Principle inoti chero shanduko mukumanikidzwa kunoshandiswa chero panguva ipi zvayo mumvura inotapuriranwa isina kudzikira mumvura yese munzira dzese.
2. Kusimudza hydraulic kunoshanda sei zvichibva paMutemo waPascal?
   • mhinduro: Muchinosimudza hydraulic, simba diki rinoshandiswa papiston iri munzvimbo diki rinoita kuti pave nekumanikidzwa kunopfuudzwa kupiston iri munzvimbo yakakura. Izvi zvinoita kuti pave nesimba guru papiston yakakura, zvichiita kuti ikwanise kusimudza zvinhu zvinorema.
3. Sei kuchinja kwekumanikidzwa kusina kudzikira muPrinciple yaPascal?
   • mhinduro: Nekuti mvura haigadzikane, kana kumanikidzwa kukaiswa kune chimwe chikamu chemvura, haigone kudzvanywa, saka inotamisa shanduko yekumanikidzwa zvakaenzana kune chimwe chikamu chemvura.
4. Kuwedzera kudzika kwemvura kunokanganisa sei kumanikidzwa kwemvura, tichifunga nezvepfungwa yaPascal?
   • mhinduro: Sezvo kudzika kuchiwedzera mumvura, kumanikidzwa kunowedzerawo nekuda kwehuremu hwemvura iri pamusoro. Izvi zvinoenderana nepfungwa yaPascal sezvo kuwedzera kwekumanikidzwa kunoitika zvakaenzana pakadzika kwakati.
5. Sei nzeve dzedu dzichirira kana tichikwira kana kuburuka nekukurumidza mundege kana kunyura pasi pemvura?
   • mhinduro: Kuchinja nekukurumidza kwekukwirira kana kudzika kunotungamira mukuchinja kukuru kwekumanikidzwa munzvimbo yakapoteredza (mhepo kana mvura). Nzeve dzedu dzinobuda senzira yekuenzanisa kumanikidzwa kwemukati nekumanikidzwa kwekunze, zvichienderana neMutemo waPascal.
6. Kana sirinji yakavharwa isina mabubble emhepo yakadzvinyirirwa, sei zvichinetsa kudzvanya mvura iri mukati?
   • mhinduro: Mvura haibatike zvakanyanya. Paunoedza kuderedza huwandu hwemvura iri mukati mesirinji, kumanikidzwa kunowedzera, zvichiramba kudzvanywa, zvichienderana nePascal's Principle.
7. Pascal's Principle inotsanangura sei chiitiko chekuputika kwedhamu kana gomba diki rikagadzirwa pasi paro?
   • mhinduro: Nekuda kwehuremu hwemvura, kumanikidzwa kuri pasi pedhamu kwakakwira. Kunyangwe gomba diki rinobvumira kumanikidzwa uku kwakanyanya pazvivakwa zvakapoteredza, izvo zvinogona kukonzera kuparara kukuru kwedhamu.
8. Sei zviri nyore kusvina mvura kubva mubhodhoro rakazadzwa kupfuura rakapera?
   • mhinduro: Bhodhoro rakazara rine mvura yakawanda iyo, kana yadzvanywa, inotumira kumanikidzwa kwacho zvinobudirira mumvura yese nekuda kwePascal's Principle. Bhodhoro rinenge risina chinhu rine mweya wakawanda, izvo zvinogona kudzvanywa, saka kumanikidzwa kwakafanana hakuburitse mvura ine simba.
9. Muma hydraulic systems, simba rekuburitsa rinogara rakakura kupfuura simba rekuisa here?
   • mhinduro: Hazvisi hazvo. Chiyero chesimba rinobuda nesimba rinopinda chinotariswa nechiyero chenzvimbo dzepiston dzinobuda nedzinopinza. Sisitimu iyi yakagadzirirwa kuwedzera simba nekuva nenzvimbo yakakura yepiston inobuda pane inopinza, asi chiyero chenzvimbo ndicho chinosarudza kuwedzera simba.
10. Tichifunga nezvepfungwa yaPascal, nei zvisikwa zvegungwa rakadzika zvine miviri yakasimba uye midiki?

• mhinduro: Zvisikwa zvemugungwa zvakadzika zvinosangana nekumanikidzwa kukuru nekuda kwehuremu hwemvura iri pamusoro. Kuti zvirarame, zvisikwa izvi zvakashanduka kuva nemiviri yakasimba uye yakamanikana inogona kutsungirira kumanikidzwa uku kwakanyanya.
