Mphamvu ya angular

Zinthu Zofunika Kwambiri

Chinthu chomwe chimachita kuyenda molunjika ili ndi mphamvu yomwe ingawerengedwe pogwiritsa ntchito fomula iyi:
p = mv
Zambiri:
p = mphamvu (gawo lapadziko lonse lapansi ndi kilogalamu mita / yachiwiri, chidule kg m/s)
m = kulemera (gawo lapadziko lonse ndi kilogalamu, chidule cha kg)
v = liwiro (gawo lapadziko lonse lapansi ndi mita / sekondi, chidule m/s)
Kuchuluka kwa thupi mu kayendedwe kozungulira komwe kuli kofanana ndi kulemera (m) mu kayendedwe kowongoka ndi mphindi ya kutopa (I). Kuchuluka kwa thupi mu kayendedwe kozungulira komwe kuli kofanana ndi liwiro (v) mu kayendedwe kowongoka ndi liwiro la angularMotero, chinthu chomwe chikuzungulira chimakhala ndi mphamvu yomwe ingawerengedwe pogwiritsa ntchito njira iyi:
Chitsanzo cha mavuto
1. Tinthu tating'onoting'ono timakhala ndi nthawi yochepa ya 2 kg m² kuzungulira ndi liwiro la angular la 2 rad/s. Dziwani mphamvu ya angular ya tinthu tating'onoting'ono!
Zokambirana
Ndizodziwika kuti :
Nthawi ya kulephera kwa tinthu tating'onoting'ono = 2 kg m²
Liwiro la angular = 2 rad/s
Anafunsa : mphamvu ya angular ya tinthu tating'onoting'ono!
Yankhani :
Fomula mphamvu ya angular :
2. Tinthu tolemera makilogalamu 1 timazungulira pa liwiro la 2 rad/s. Utali wa njira ya tinthuto ndi mamita awiri. Dziwani mphamvu ya angle ya tinthuto!
Zokambirana
Amadziwika kuti:
Kulemera kwa tinthu tating'onoting'ono (m) = 1 kg
Liwiro la tinthu tating'onoting'ono = 2 rad/s
Utali wa njira ya tinthu (r) = mamita awiri
Anafunsa: Mphamvu ya tinthu tating'onoting'ono?
Yankho:

3. Tinthu tolemera magalamu 0,5 timachita kuyenda kozungulira ndi liwiro lokhazikika la angular la 2 rad s^-1Ngati utali wa njira ya tinthu tating'onoting'ono ndi 10 cm, ndiye kuti mphamvu ya angular ya tinthu tating'onoting'ono ndi...
A. 1 × 10^-5 makilogalamu m² /s
B. 2 × 10^-5 makilogalamu m² /s
C. 3 × 10^-5 makilogalamu m² /s
D. 4 × 10^-5 makilogalamu m² /s
E. 5 × 10^-5 makilogalamu m² /s
Kukambirana:

Mphamvu Yozungulira tinthu tating'onoting'ono:
L = (0,5 x 10)^-5 makilogalamu m²)(2 rad/s) = 1 x 10^-5 makilogalamu m²/s
