Question

Yg di bulatin ya tolong cepat..plis...dan hrs..btl ok..

Answer 1

Diketahui :
lk = 120 m
KM 1 = 2
KM 2 = 3

ditanyakan :
posisi = ?

lk1/lb1 = KM1
120/lb = 2
lb = 60 m

l = 180

KM2 = lk 2 / lb
3 = 180-lb/lb
3 lb = 180 - lb
4 lb = 180
lb = 45

jadi titik tumpu digeser 15 m mendekati titik beban (C)
