Washing in the left wing of a monoplane will increase?

  1. Only lift

  2. Only drag

  3. Both drag and lift

  4. Neither drag nor lift

The correct answer is: Both drag and lift

Washing the left wing of a monoplane will increase both drag and lift. This is because during the washing process, the dirt and contaminants on the wing's surface are removed. By cleaning the wing, the smoothness of the surface is restored, reducing drag caused by surface imperfections. Additionally, the removal of dirt and other debris decreases the disruption to the airflow over the wing, resulting in an increase in lift generated by the wing. Therefore, washing the left wing of a monoplane will positively affect both drag and lift.
