Ajet 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 12.0 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.

(a). The normal force exerted by the ground on the front wheel is .

(b). The normal force exerted by the ground on each of the two rear wheels is

Explanation:

Given that,

Weight of jet

Distance = 16 m

Second distance = 12.0 m

We need to calculate the normal force exerted by the ground on the front wheel

Using formula of torque

Where, W = weight of jet

=lever arms for the forces

=lever arms for the forces W

Put the value into the formula

(b). We need to calculate the normal force exerted by the ground on each of the two rear wheels

The sum of vertical forces equal to zero.

We using 2 for two rear wheels

Put the value into the formula

Hence, (a). The normal force exerted by the ground on the front wheel is .

(b). The normal force exerted by the ground on each of the two rear wheels is
