Pompa hidrolik – Usaha

Diketahui :

  • A1 = 1 cm^2
  • A2 = 100 cm^2
  • F2 = 5.000 N
  • F1 = -5 N
  • F2 = -10 N
  • F3 = 30 N
  • s = perpindahan = 2 m

Ditanya :

  • F1 = ?
  • W = usaha ?

Jawaban 1

F1/A1 = F2/A2

F1/1 = 5.000/100

F1 = 1 × 5.000/100

F1 = 5.000/100

F1 = 50 N ✔

Jawaban 2

Cari resultan gaya

R = (-F1) + (-F2) + F3

R = (-5) + (-10) + 30

R = (-15) + 30

R = 15 N

Cari usaha

W = F × s

W = 15 × 2

W = 30 J ✔

Jawaban:

8. C. 50 N

9. C. 30 joule
