Masa pilot: m=75kg
Greutate pilot: G=m*g=75*10=750N
Viteza avion: v=180km/h=180*1000/3600m/s=180*10/36=50m/s
Forta centrifuga: Fcf=m*v²/R=75*50²/60=75*50*5/6=3125N
In punctul inferior, forta centrifuga si greutate sint coliniare si orientate in acelasi sens, in jos
Deci R=G+Fcf
Raspuns: R=750N+3125N=3875N
