Mutemo waHooke - matambudziko nemhinduro

1. Girafu yesimba (F) ichienzaniswa nekureba (x)) inoratidzwa mumufananidzo uri pazasi. Tsvaga chitubu chinoramba chiripo!

mhinduro

Mutemo waHooke formula :

k = F / x

F = simba (Newton)

k = chitubu chisingachinji (Newton/mita)

x = kuchinja kwehurefu (mamita)

Chirimo chinogara kwenguva refu:

k = 10 / 0.02 = 20 / 0.04

k = 500 N/m

2. Sarudza chitubu chinogara.

mhinduro

Chirimo chinogara kwenguva refu:

k = F / x

k = 5 / 0.01 = 10 / 0.02 = 15 / 0.03 = 20 / 0.04

k = 500 N/m

3. Chitubu A chine hurefu hwepakutanga hwe60 cm uye chitubu B chine hurefu hwepakutanga hwe90 cm. Chitubu A chine hurefu hwe100 N/m, chitubu B chine hurefu hwe200 N/m. Chiyero chekuchinja kwehurefu hwechitubu A nekuchinja kwehurefu hwechitubu B ndeche…

Zvinozivikanwa:

Chimiro chechirimo A (k)_A) = 100 N/m

Chimiro chenguva dzose chechirimo B (k)_B) = 200 N/m

Simba pachitubu A (F)_A) = F

Simba pachitubu B (F)_B) = F

Kuda: Δl_A : Δl_B

Solution:

Fomura yemutemo waHooke:

Δl = F / k

Δl = kuchinja kwehurefu, F = simba, k = kusachinja-chinja

Kuchinja kwehurefu hwechitubu A:

Δl_A =F_A / k_A = F / 100

Kuchinja kwehurefu hwechitubu B:

Δl_B =F_B / k_B = F / 200

Chiyero chekuchinja kwehurefu hwechitubu A nekuchinja kwehurefu hwechitubu B:

Δl_A : Δl_B

F/100 : F/200

1/100: 1/200

1/1: 1/2

2: 1

4. Tambo yenylon ine urefu hwepakutanga hwemasendimita makumi maviri, inodhonzwa nesimba re10 N. Kuchinja kwehurefu hwetambo i2 cm. Sarudza hukuru hwesimba kana kuchinja kwehurefu kuri 6 cm.

Zvinozivikanwa:

Simba (F) = 10 N

Kuchinja kwehurefu (Δl) = 2 cm = 0.02 m

Zvaidiwa: hukuru hwesimba (F) kana Δl = 0.06 m.

Solution:

Nguva dzose:

k = F / Δl

k = 10 / 0.02 = 500 N/m

Hukuru hwesimba (F) kana Δl = 0.06 m :

F = kx

F = (500)(0.06)

F = 30N
