nomor 9 tolong jawab

ELASTISITAS
• rangkaian pegas

k = 300 N/m
∆x = 10 cm = 0,1 m
F = __?


Rangkaian A, 2 pegas diseri
ka = k/2 = 150 N/m

Fa = ka ∆x
F₁ = 150 • 0,1 = 15 N ← jwb


Rangkaian B, 3 pegas diseri
kb = k/3 = 100 N/m

Fb = kb ∆x
F₂ = 100 • 0,1 = 10 N ← jwb


Rangkaian C, 4 pegas diparalel
kc = 4k = 1200 N/m

Fc = kc ∆x
F₃ = 1200 • 0,1 = 120 N ← jwb
