3 su'aalood oo ku saabsan isle'egta xawaaraha xagasha
1. Shay ku socda waddo wareegsan wuxuu leeyahay gacan 0.5 m. Walxaha waxay awoodaan inay daboolaan xagal 60π rad ah 15 ilbiriqsi gudahood. Go'aami xawaaraha xagasha ee shayga.
La yaqaan
Gacanka (r) = 0.5 mitir
Xagasha (θ) = 60π rad
Muddada (t) = 15 ilbiriqsi
La Raadinayo: Xawaaraha xagasha (ω)
Solution:
θ = ω t
60π = ω (15)
ω = 60π / 15 = 4π rad/s
2. Taayir baaskiil oo leh gacan 30 cm ah ayaa ku wareegaysa xawaare joogto ah. Waalka taayirka ayaa ku wareegi kara xagal 120π rad ah muddo 10 ilbiriqsi ah. Go'aami xawaaraha xagasha.
La yaqaan
Gacanka (r) = 30 cm
Xagasha (θ) = 120π rad
Muddada (t) = 10 ilbiriqsi
La Raadinayo: Xawaaraha xagasha (ω)
Solution:
θ = ω t
120π = ω (10)
ω = 120π / 10 = 12π rad/s
3. Xarigga waxaa lagu duubay giraangir leh gacan R = 25 cm sida lagu muujiyey. Haddii barta xarigga (dhibicda A) ay leedahay xawaare dhan 5 m/s markaa xawaaraha wareegga giraangiraha waa…
La yaqaan
Gacanka (r) = 25 cm = 0.25 mitir
Xawaaraha (v) = 5 m/s
La Raadinayo: Xawaaraha xagasha (ω)
Solution:
Qaacidada xiriirka ka dhexeeya xawaaraha xagasha, xawaaraha toosan iyo gacanka:
v = r ω
5 = (0,25) ω
ω = 5 / 0,25 = 20 rad/s
