Jawaban:
24 cm
Penjelasan dengan langkah-langkah:
Dik :
F = 25 kg
W / Fb = 20 kg
Lb = 30 cm
Dit : Lk
Lk = (W.Lb) / F
= (20.30) / 25
= 600 / 25
= 24 cm
Penjelasan dengan langkah-langkah:
Dik :
W = 20 Kg
F = 25 Kg
Lb = 30 Cm = 0,3 m
Dit : Lengan kuasa (Lk)
Jawab :
W × Lb = F × Lk
20 × 0,3 = 25 × Lk
6 = 25 × Lk
Lk = 6/25 m
Lk = 0,24 m = 24 Cm
