exo 1 (Chap 8) : Skieur

alpha = 10°
beta = 30°
m = 60kg

1: négliger les frottements,
oui car piste verglacée

2: calculer P, donner les caracteristiques,
P=m*g = 60*9,81 = 586,6 N 
point application : centre gravité skieur
direction : parallèle au sol
sens : vers le bas
intensité : P=m*g

3: autres forces, 
P-> + T-> + R-> = 0
ox = -P sin(10°)+Tcos(30°)+0=0
T= *P ((sin(10°)) / (cos(30°)))
 = 60*9,81 * sin(10°)/cos(30°)
 = 1.2*10*2N
