Question

Kak, tolong bantu jawab soal nomor 8-9 dong kak...

Answer 1

8. Sistem pegas paralel

F = kp . x

kp = F/x = 30/0,1

kp = 300 N/m

3 Pegas identik yang dihubungkan paralel berlaku

kp = k + k + k

kp = 3 k

k = 1/3.kp = 1/3. 300

k = 100 N

konstanta masing-masing pegas 100 N.

9. hubungan paralel 3 pegas

kp = k1+k2+k3 = 3.k

kp = 1500 N/m

Konstanta pegas total adalah seri kp dan k4

1/ks = 1/1500 + 1/500

1/ks = 4/1500

ks = 1500/4 = 375 N/m

F = ks. x

x = F/ks = 40/375

x = 0,11 m = 11 cm
