Zvidimbu zviri muchikamu chimwe chete chekuenzanisa - kushandiswa kwematambudziko ekutanga emutemo waNewton nemhinduro dzawo

^{1. Huremu hwechinhu, m = 10 kg, chakatsigirwa netambo. Tsvaga kusimba kwetambo!} g = 10 m/s ²

Zvinozivikanwa:

Huremu (m) = 10 kg

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

Zvinodiwa: Simba rekumanikidza (T)

Solution:

ΣF _y = 0

T – w = 0

T = w

T = mg

T = (10 kg)(10 m/s ² ) = 100 kg m/s ²

T = 100 Newton

2. Huremu hwechinhu chacho i10 kg. Tsvaga kumanikidzwa kuri mutambo….. Kukurumidza kunokonzerwa negiravhiti = 10 m/s ².

mhinduro

Zvinozivikanwa:

Huremu (m) = 10 kg

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

Zvinodiwa: Simba rekumanikidza (T)

Solution:

^{w = uremu = mg = (10 kg)(10 m/s2}) = 100 kg m/s²

T ₁ = simba rekumanikidza 1

_{T 1x} = chikamu che x chesimba rekumanikidzwa 1 = T ₁ cos 45 ^o = 0.7 T ₁

_{T 1y} = chikamu che y chesimba rekumanikidzwa 2 = T ₁ sin 45 ^o = 0.7 T ₁

T ₂ = simba rekumanikidza 2

_{T 2x} = chikamu che x chesimba rekumanikidzwa 2 = T ₂ cos 45 ^o = 0.7 T ₂

_{T 2y} = chikamu che y chesimba rekumanikidzwa 2 = T ₂ sin 45 ^o = 0.7 T ₂

Mamiriro ekuenzana ΣF = 0.

y akisi:

ΣF _y = 0

T _1y + T _2y – w = 0

0.7T ₁ + 0.7T ₂ – 100 = 0

0.7T ₁ + 0.7T ₂ = 100 —– muyero 1

akisi x:

ΣF _x = 0

T _2x – T _1x = 0

0.7T ₂ – 0.7T ₁ = 0

0.7T ₂ = 0.7T ₁

T ₂ = T ₁ —– equation 2

Sarudza hukuru hweT ₁ :

0.7T ₁ + 0.7T ₁ = 100

1.4T ₁ = 100

T ₁ = 100 / 1.4

T ₁ = 71.4 Newton

T ₁ = T ₂ saka T ₂ = 71.4 Newtons
