    physics center of gravity problems?
    A jet transport has a weight of 1.00x10^6N and is at rest on the runway. The two rear wheels are 15.0m 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 wheel and on each of the two rear wheels.

    Start by adding up the torques as measured about the rear wheels, and apply . There are only two torques to worry about for this step - the weight of the plane acting through the center of gravity and the weight carried by the nose wheel. Can you take it from here?
