Ụkpụrụ Pascal - nsogbu na ngwọta

1. A maara:

Mpaghara A 1 = 10 cm 2

Mpaghara A 2 = 100 cm 2

Ike 2 (F 2 ) = 100 Newton

Achọtara: Ike 1 (F 1 )

Ngwọta:

P = F / A

P = nrụgide , F = ike , A = mpaghara

P1 = F.1 / EGO1
P2 = F.2 / EGO2

P1 =P2
F1 / EGO1 = F.2 / EGO2

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. Ọ bụrụ na mpaghara A 1 = 0.001 m2 na mpaghara A 2 = 0.1 m2 , ike ntinye mpụga F 1 = 100 N, mgbe ahụ ike mmepụta mpụga F 2?

A maara:Ụkpụrụ Pascal - nsogbu na ngwọta 2

Mpaghara A 1 = 0.001 m 2

Mpaghara A 2 = 0.1 m 2

Ike ntinye mpụta F 1 = 100 Newtons

Achọtara : Ike mmepụta mpụta (F 2 )

Ngwọta:

P1 =P2
F1 / EGO1 = F.2 / EGO2

100 N / 0.001 m 2 = F 2 / 0.1 m 2

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. Ibu ụgbọ ala = 16,000 N. Kedu ike ntinye mpụta F…

A maara:Ụkpụrụ Pascal - nsogbu na ngwọta 3

Ibu ụgbọ ala (w) = 16,000 N

Mpaghara B (A B ) = 4000 cm 2 = 4000 / 10,000 m 2 = 4 / 10 m 2 = 0.4 m 2

Mpaghara A (A A ) = 50 cm 2 = 50 / 10,000 m 2 = 0.005 m 2

Achọtara: Ike F

Ngwọta:

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.

Mpaghara A bụ 60 cm 2 na mpaghara B bụ 4,200 cm 2 , chọpụta ike ntinye mpụta nke F.

A maara:Ụkpụrụ Pascal - nsogbu na ngwọta 3

Mpaghara A (A A ) = 60 cm 2

Mpaghara B (A B ) = 4200 cm 2

Ibu w (w) = 3500 Newton

A chọrọ: F 1

Ngwọta:

A gbakọọ ike nke F site na iji usoro nke ụkpụrụ Pascal :

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

F1 = Newton 50

5. Nweli elu hydraulic nwere nnukwu akụkụ obe na obere akụkụ obe. Mpaghara obe buru ibu dị okpukpu iri abụọ nke obere mpaghara obe. Ọ bụrụ na enyere ya ike ntinye nke 25 N na obere akụkụ obe ahụ, chọpụta ike mmepụta.

A maara:

Obere mpaghara obe (A 1 ) = A

Nnukwu mpaghara obe (A 2 ) = 20A

Ike ntinye (F 1 ) = 25 N

Achọtara: Ike mmepụta (F 2 )

  1. Gịnị bụ Ụkpụrụ Pascal?
    • Azịza: Ụkpụrụ Pascal kwuru na mgbanwe ọ bụla na nrụgide etinyere n'ebe ọ bụla n'ime mmiri na-ebufe n'enweghị mbelata n'ime mmiri ahụ n'akụkụ niile.
  2. Kedu otu igwe mbuli elu hydraulic si arụ ọrụ dabere na Pascal's Principle?
    • Azịza: N'ime ebuli hydraulic, obere ike etinyere na piston mpaghara dị obere na-emepụta nrụgide nke a na-ebufe na piston mpaghara buru ibu na-enweghị mbelata. Nke a na-eme ka ike buru ibu na piston buru ibu, na-eme ka o nwee ike ibuli ihe dị arọ.
  3. Gịnị mere mgbanwe nrụgide ji dị obere na Ụkpụrụ Pascal?
    • Azịza: Ebe ọ bụ na mmiri anaghị agbaze agbaze, mgbe a na-etinye nrụgide n'otu akụkụ nke mmiri ahụ, ọ nweghị ike ịpịkọta, yabụ ọ na-ebufe mgbanwe nrụgide ahụ n'otu akụkụ ahụ nke mmiri ahụ.
