W = 480 N
Lb = 25 cm
F = 120 N
W.Lb = F. Lk
480 . 25 = 120 . Lk
100 = Lk
titik tumpu digeser 20 cm mendekati titik kuasa, sehinga :
• Lk = 100-20 = 80 cm
• Lb = 25+20 = 45
agar tetap seimbang yaitu mengatur besar gaya dengan panjang lengan kuasa tetap
F. 80 = 480 . 45
F = 480 . 45 : 80
F = 6 . 45
F = 270 N
