Diket: W = 900 N L = 4 m lb = 1m lk = L -lb = 4 - 1 = 3m Dit: a. F....? b. Km jawab: a. F . lk = W . lb F . 3 = 900 . 1 F = 900/3 F = 300 N besar gaya = 300 N , b. Km = W/F atau Km = lk/lb Km = 900/300 Km = 3
W = 900 N
L = 4 m
lb = 1m
lk = L -lb = 4 - 1 = 3m
Dit:
a. F....?
b. Km
jawab:
a.
F . lk = W . lb
F . 3 = 900 . 1
F = 900/3
F = 300 N
besar gaya = 300 N
,
b.
Km = W/F atau Km = lk/lb
Km = 900/300
Km = 3
