2. - Translation : Ec = 1/2 mv^2
   - Rotation : Ec = 1/2 Jw^2

3.Ep = mgz
4. Tout corps plongé dans un fluide subit une force verticale
dirigée vers le haut égale au poids du volume de fluide déplacé

FA = ρfluide . Vi . g

Données :
  - diamètre = 50mm -> rayon = 0.025m
  - longeur = 0.6m
  - cylindre à moitié immergé
  - ρ eau = 1000 kg/m^3

Volume total :
  V = πr^2L = 0.00118m^3
Volume immergé :
  Vi = 1/2V = 0.00059m^3

FA =ρfluide . Vi . g = 5.8N

6. η = Es/Ee = Ps/Pe

8. E = P x t

9. Débit : Q = V . S        Q = Vol/delta t
10. Phyd = Pr (N/m^2) . Q (m^3 /s)

II. Cr = Cm x r x ηr

III. Cr = F x R
