Jika titik kuasa digeser 20cm mendekati penumpu hitung gaya kuasa dan KM​

W x Lb = F x Lk

1000 x 50 = F x 200

F = 1000 x 50/200

F = 50.000/200

F = 250 N

Titk.kuasa digeser 20 cm mendekati penumpu, berarti Lk = 200 -20 cm = 180 cm

1000 x 50 = F x 180

F = 1000 x 50/180

F = 277,78 N

KM = W/F = 1000/250 = 4
