I need help finding the forces when an aircraft’s jump cable catches to stop a plane on an aircraft carrier ship. The aircraft is traveling at 110 mph with the front of the plane 3 feet off the deck of the ship. If the assumption is made that the cable stops the aircraft immediately (the cable is not elastic), what would be the estimated impact force on the front end of the aircraft with the following conditions?
-The aircraft is 24 feet long
-1000 lbs located 4 feet above rear axle (pivot point)
-5000 lbs located 5 feet above center of plant (when plane is level)
-1500 lbs located 3 feet above front axle
-Do NOT ignore gravity
-Assume no impact absorbed by the front tire
I think it involves dynamics with momentum, kinetic energy, and maybe more.
L (linear momentum) = mass * velocity
A (angular momentum) = L x r (cross product of linear momentum and vector)
Tried using angular momentum (lb ft2 / sec) but that will not add with gravitational force multiplied by distance and mass (lb ft2 / s2). I'm really stuck here please help get me started!
