ʻAtikala e pili ana i ka Nā pūnāwai ma ke ʻano moʻo a me ke ʻano like
1. Nā pūnāwai ma ke ʻano moʻo
Inā ua hoʻopili ʻia ka pūnāwai ma ke ʻano moʻo, e like me ke kiʻi ma ka ʻaoʻao, a laila:
1. ʻO ka piʻi ʻana o ka lōʻihi o ka pūnāwai = ka piʻi ʻana o ka lōʻihi 1 + ka piʻi ʻana o ka lōʻihi 2
Δ y = Δ y 1 + Δ y 1
2. ʻO ka ikaika i ʻike ʻia e ka pūnāwai like = ka ikaika i ʻike ʻia e ka pūnāwai 1 = ka ikaika i ʻike ʻia e ka pūnāwai 2
Fs = F1 = F2
3. ʻO ke kūpaʻa o ka pūnāwai like (k s )
1/k s = 1/k 1 + 1/k 2
Laʻana pilikia 1:
ʻElua mau pūnāwai like i hoʻopili ʻia ma ke ʻano moʻo me kahi kūpaʻa o 100 N/m. Inā hāʻawi ʻia ka hoʻonohonoho ʻana o ka pūnāwai i kahi ukana i hoʻonui ʻia i 4 cm ka lōʻihi, a laila ʻo ka hoʻonui ʻana o ka lōʻihi o kēlā me kēia pūnāwai he …
pāʻoihana:
ʻO ka huina piʻi ʻana o ka lōʻihi o nā pūnāwai ʻelua he 4 kenimika, no laila ʻo ka piʻi ʻana o ka lōʻihi o kēlā me kēia pūnāwai he 2 kenimika.
2. Nā pūnāwai ma ke ʻano like
Inā pili like ka pūnāwai, e like me ke kiʻi ma ka ʻaoʻao, a laila:
1. ʻO ka piʻi ʻana o ka lōʻihi o ka pūnāwai like = ka piʻi ʻana o ka lōʻihi o ka pūnāwai 1 = ka piʻi ʻana o ka lōʻihi o ka pūnāwai 2
Δ y = Δ y 1 + Δ y 1
2. ʻO ka ikaika i ʻike ʻia e ka pūnāwai like = ka ikaika i ʻike ʻia e ka pūnāwai 1 + ka ikaika i ʻike ʻia e ka pūnāwai 2
Fs = F1 + F2
3. ʻO ke kūpaʻa o ka pūnāwai like (k p )
kp = k1 + k2
Laʻana pilikia 2:
ʻElua mau pūnāwai me kēlā me kēia c mau i hoʻonohonoho ʻia ma ke ʻano like. ʻO ke kūpaʻa pūnāwai o kēia hoʻonohonoho ʻana e lilo i …
pāʻoihana:
ʻO ke kūpaʻa o ka pūnāwai like (kp ) = c + c = 2c
