Her father replied that she could go, but that he suspected her tires would probably need some extra air. Why might he say this?

The lift force on the airplane wing is given by the distributed load L(x) = 15(1- 0.04x) KN/m, the engine has a weight of 20 KN, and the weight of the wing is given by w(x) = (5-0.5x) KN. Determine the reaction force and moments at the root of the wing.
