# Torque Question

PianoMan
A jet transport has a weight of 1.00x10^6 N and is at rest on the runway. The two rear wheels are 15m behind the front wheel, and the plane's center of gravity is 12.6m behind the front wheel. Determine the normal force exerted by the ground on the front whell and each of the two rear wheels.

Ok, so I drew a sketch. I've got front wheel, rear wheels, in between the two i have the center of gravity, pushing down with 1x10^6 N. Behind are the rear wheels pushing up with an FN and in front of it the front wheel is pushing up with an FN. There's 15 m of distance between them. The distance from the center of gravity to the front wheel is 12.6 m, to the back wheels it is 2.4 m. But now, I don't know what to do. I can't find Torque (r * F) because even though I have distances from the center of gravity (r) I don't know an F. That's what I'm trying to find...which I can't find without Torque. lol. Any help?
