W = 800 N
s = 8 m
h = 2m
dit : KM ?
dijawab :
F = h/s x W
= 2/8 x 800
= 200 N
jadi Keuntungan Mekanis :
KM = W/F
= 800/200
= 4
CARA CEPAT :
KM = s/h
= 8/2
= 4
diketahui:
W = 800N
l = 8m
h = 2m
ditanya:
KM = ..?
jawab:
w * h = f * l
800N * 2m = f * 8m
1600 = 8f
1600/8 = f
200 = f
KM = W/F
= 800/200
= 4
CARA PENDEK
km = L/H
= 8m/2m
= 4
