Dik :
K₁ = 600 N/m
K₂ = 400 N/m                       Berapak Kontanta Pegas pengganti (Kτ)?
K₃ = 500 N/m

 \frac{1}{Kτ}  =  \frac{1}{K₁}  + \frac{1}{K₂}  +  \frac{1}{K₃}
 \frac{1}{Kτ} = \frac{1}{600} + \frac{1}{400} + \frac{1}{500}
 \frac{1}{Kτ} = \frac{500+750+600}{300000}
Kτ = \frac{300000}{1850} = 162 \frac{6}{37} N/m

Semoga Membantu!!1
