As part of a test, the two aircraft engines are revved up and the propeller pitches are adjusted so as to result in the fore and aft thrusts shown. What force F must be exerted by the ground on each of the main braked wheels at \( A \) and \( B \) to counteract the turning effect of the two propeller thrusts? Neglect any effect of the nose wheel C which is turned \( 90^{\circ} \) and unbraked.
