Mafunso atatu okhudza equation ya liwiro la Angular
1. Chinthu choyenda munjira yozungulira chimakhala ndi utali wa 0.5 m. Tinthu timeneti timatha kuphimba ngodya ya 60π rad mu masekondi 15. Dziwani liwiro la angular la chinthucho.
Zodziwika:
Ulalo wozungulira (r) = mamita 0.5
Ngodya (θ) = 60π rad
Nthawi yopuma (t) = masekondi 15
Kufunidwa: Liwiro la angular (ω)
yankho;
θ = ω t
60π = ω (15)
ω = 60π / 15 = 4π rad/s
2. Gudumu la njinga lokhala ndi utali wa masentimita 30 limazungulira pa liwiro losasintha. Vavu ya tayala imatha kuzungulira pa ngodya ya 120π rad kwa masekondi 10. Dziwani liwiro la angular.
Zodziwika:
Utali wozungulira (r) = 30 cm
Ngodya (θ) = 120π rad
Nthawi yopuma (t) = masekondi 10
Kufunidwa: Liwiro la angular (ω)
yankho;
θ = ω t
120π = ω (10)
ω = 120π / 10 = 12π rad/s
3. Chingwecho chazunguliridwa ndi gudumu lokhala ndi utali wozungulira R = 25 cm monga momwe zasonyezedwera. Ngati mfundo pa chingwe (mfundo A) ili ndi liwiro la 5 m/s ndiye kuti liwiro lozungulira la gudumu ndi…
Zodziwika:
Ulalo wozungulira (r) = 25 cm = 0.25 mamita
Liwiro (v) = 5 m/s
Kufunidwa: Liwiro la angular (ω)
yankho;
Fomula yolumikizirana pakati pa liwiro la angular, liwiro la mzere ndi utali wozungulira:
v = r ω
5 = (0,25) ω
ω = 5 / 0,25 = 20 rad/s
