1-3 tlong beserta rumus

1.km=l/h
=9/3
=3
Fk=Fb/km
=750/3
=250 N
2.km=Lk/Lb
=4/2
=2
gaya=beban/km
=3000/2
=1500 N
3.Lb=1 Lk=5 km=5/1=5
gaya=3000/5
=600 N

No. 1
--------
Diket :
Berat lemari, W = 750 N
Tinggi loteng, h = 3 m
Panjang bidang miring, s = 9 m

Tanya :
Gaya kuasa, F = __?

Jawab :
F = (h/s).W
F = (3/9)•750
F = (1/3)•750
F = 250 N

No.2
-------
Diket :
Berat beban, W = 3000 N
Panjang lengan beban, Lw = 2 m
Panah lengan gaya, Lf = 4 m

Tanya ;
Gaya kuasa, F = __?

Jawab :

F = (Lw/Lf).w
F = (2/4)•3000
F = (1/2)•3000
F = 1500 N

No. 3
--------
Diket :
Berat beban, W = 3000 N
Panjang tuas, L = 6 m
Pangang lengan beban, Lw = 1 m

Tanya :
Gaya kuasa, F = __?

Jawab :
Step 1
---------
Cari dulu panjang lengan kuasa yak,

Lf + Lw = L
Lf + 1 = 6
Lf = 5 m

Step 2
---------
F = (Lw/Lf).w
F = (1/5)• 3000
F = 600 N
