Question
A jet transport has a weight of 1.87 x 106 N and is at rest on the runway. The two rear wheels are 16.0 m behind the front wheel, and the plane's center of gravity is 12.1 m behind the front wheel. Determine the normal force exerted by the ground on (a) the front wheel and on (b) each of the two rear wheels.
Explanation / Answer
we have equations...
mg=Ff+2Fr....Newtons Law
Ff*12.1=2*Fr*3.9...Body should not tople
mg=(1+(12.1/3.9))Ff
Ff=mg/((1+(12.1/2/3.9)))=455.81*10^3N
Fr=707.09*10^3N
