Disusun seri atau paralel?

jika pegas disusun seri
1/kp = 1/200 + 1/150 + 1/400 + 1/300 + 1/500
1/kp = 30 + 40 + 15 + 20 + 12 / 6000
1/kp = 117/6000
kp = 6000/117
kp = 51,28 N

jika pegas disusun paralel
kp = 200 +150 + 400 + 300 + 500
kp = 1550 N

perpanjangan jika seri
Δx = f/k
Δx = 80/ 51,28 = 1,56

perpanjangan jika paralel
Δx = f/k
Δx = 80/1550 =0,05
