ELASTISITAS• rangkaian pegas
2 pegas disusun seri
k₁ = 200 N/m
k₂ = 500 N/m spt inilah satuan
F = 100 N
∆x = __?
konstanta pegas susunan seri.
1/kₛ = 1/k₁ + 1/k₂
1/kₛ = 1/200 + 1/500
1/kₛ = 5/1000 + 2/1000 = 7/1000
kₛ = 1000/7 N/m
pertambahan panjang
F = kₛ ∆x
100 = 1000/7 • ∆x
∆x = 100 × 7/1000
∆x = 7/10 = 0,7 m ✓
