KELAS = 8PELAJARAN = FISIKA
KATEGORI = Pesawat sederhana
KATA KUNCI = tuas, gaya, lengan kuasa, lengan beban
Diketahui :
L = 2,5 m
F = 750 N
Lb = 0,5 m
Ditanyakan : F ?
Dijawab :
Lk = L - Lb
= 2,5 - 0,5
= 2 m
Jadi besar gaya minimal yg diperlukan :
F x Lk = W x Lb
F x 2 = 750 x 0,5
F = 375/2
F = 187,5 N
