A small airplane is sitting at rest on the ground. Its center of gravity is 2.58 m behind the nose of the airplane, the front wh

Answer:

The percentage of the weight supported by the front wheel is A= 19.82 %

Explanation:

From the question we are told that

The center of gravity of the plane to its nose is $z = 2.58 m$

The distance of the front wheel of the plane to its nose is $l = 0.800\ m$

The distance of the main wheel of the plane to its nose is $e = 3.02 \ m$

At equilibrium the Torque about the nose of the airplane is mathematically represented as

$mg (z- l) - G_B *(e - l) = 0$

Where m is the mass of the airplane

$G_B$ is the weight of the airplane supported by the main wheel

$G_B =\frac{mg (z-l)}{(e - l)}$

Substituting values

$G_B =\frac{mg (2.58 -0.8 )}{(3.02 - 0.80)}$

$G_B = 0.8018 mg$

Now the weight supported at the frontal wheel is mathematically evaluated as

$G_F = mg - G_B$

Substituting values

$G_F = mg - 0.8018mg$

$G_F = (1 - 0.8018) mg$

$G_F = 0.1982 mg$

Now the weight of the airplane is = mg

Thus percentage of this weight supported by the front wheel is $A = 0. 1982 *100 =$ 19.82 %
