Question

A jet transport has a weight of 9.31 x 106 N and isat rest on the runway. The two rear wheels are 16.0 m behind thefront wheel, and the plane's center of gravity is 10.2 m behind thefront wheel. Determine the normal force exerted by the ground on(a) the front wheel and on (b)each of the two rear wheels see link for the pic; http://img38.imageshack.us/img38/6549/w1593int.gif A jet transport has a weight of 9.31 x 106 N and isat rest on the runway.

Explanation / Answer

a)Taking moments about the point where the rear wheel touches theground: Ff x16=mg(16-10.2)   =>Ff =3.375x 106 N b)Taking moments about the point where the front wheel touches theground: mg(10.2)=2Fr x 16   =>Fr =2.968x 106 N
