11.43: For the airplane to remain in level flight, both 0 and 0 = = τ F . Taking the clockwise direction as positive, and taking torques about the center of mass, Forces: 0 wing tail = + - - F W F Torques: 0 ) m 3 (. ) m 66 . 3 ( wing tail = + - F F A shortcut method is to write a second torque equation for torques about the tail, and solve for the . 0 ) m 36 . 3 ( ) N 6700 )( m 66 . 3 ( : wing wing = + - F F This gives .

Unformatted text preview: 600 N 7300 N 6700 and ), up ( N 7300 tail wing-=-= = F F Note that the rear stabilizer provides a downward force, does not hold up the tail of the aircraft, but serves to counter the torque produced by the wing. Thus balance, along with weight, is a crucial factor in airplane loading....
