Springs motsatizana komanso motsatizana

Nkhani yokhudza Springs motsatizana komanso motsatizana

1. Springs mu mndandanda

Ngati kasupe walumikizidwa motsatizana, monga momwe zilili pachithunzi chomwe chili pambali, ndiye kuti:

1. Kuwonjezeka kwa kutalika kwa masika = kuwonjezeka kwa kutalika 1 + kuwonjezeka kwa kutalika 2

Δy = Δy₁ + Δy₁

2. Mphamvu yomwe imachitikira ndi kasupe wofanana = mphamvu yomwe imachitikira ndi kasupe 1 = mphamvu yomwe imachitikira ndi kasupe 2

F_s =F₁ =F₂

3. Chosasintha cha masika chofanana (k)_s)

1/p_s = 1/k₁ + 1/k₂

Chitsanzo cha vuto 1:

Masipule awiri ofanana ali ndi mphamvu yokhazikika ya 100 N/m yolumikizidwa motsatizana. Ngati dongosolo la masipulero lapatsidwa mphamvu kotero kuti liwonjezere kutalika kwa 4 cm, ndiye kuti kutalika kwa masipulero aliwonse ndi ...

yankho;

Kuwonjezeka konse kwa kutalika kwa masipu awiriwa ndi 4 cm, motero kuwonjezeka kwa kutalika kwa masipu onse ndi 2 cm.

2. Masipuleti motsatizana

Ngati kasupe walumikizidwa mofanana, monga momwe zilili pachithunzi chomwe chili pambali, ndiye kuti:

1. Kuwonjezeka kwa kutalika kwa kasupe wofanana = kuwonjezeka kwa kutalika kwa kasupe 1 = kuwonjezeka kwa kutalika kwa kasupe 2

Δy = Δy₁ + Δy₁

2. Mphamvu yomwe imachitikira ndi kasupe wofanana = mphamvu yomwe imachitikira ndi kasupe 1 + mphamvu yomwe imachitikira ndi kasupe 2

F_s =F₁ +F₂

3. Chosasintha cha masika chofanana (k)_p)

kp = k₁ +k₂

Chitsanzo cha vuto 2:

Masipu awiri aliwonse okhala ndi c yosasinthika yokonzedwa motsatizana. nthawi zonse ya masika dongosolo ili limakhala…

yankho;

Chokhazikika chofanana cha kasupe (k)_p) = c + c = 2c
