how do quadcopters counteract the torque forces created by each of the four rotors? (5.b.3) rotors that sit on opposite sides from one another spin in opposing directions all four rotors spin counter - clockwise the main body absorbs all torque forces a computer is used to limit the amount of torque from each rotor trim systems are designed to _______. (5.b.2) relieve the pilot of the need to maintain constant pressure on the flight controls. be used during approach and landing to increase wing lift. move in the opposite direction from one another to control roll. increase drag for rapid descents and to reduce lift after landing. true or false. pitch stability refers to the movement of an aircraft’s nose up and down around its lateral axis. (5.a.1) true false

Explanation:

First Question (How do quadcopters counteract the torque forces...):

Quadcopters counteract torque by having opposite rotors spin in opposite directions (e.g., two clockwise, two counter - clockwise) to cancel out torque. The option "All four rotors spin counter - clockwise" would create unbalanced torque. The main body can't absorb all torque, and a computer doesn't limit torque to counteract it (it's about direction of rotation). So the correct option is the one with opposite rotors spinning in opposing directions.

Trim systems in aircraft are used to reduce the pilot's workload by eliminating the need for constant pressure on flight controls. The option about increasing wing lift during approach/landing is for flaps. Moving opposite for roll is about ailerons. Increasing drag for descents is for spoilers. So the correct option is the one about relieving the pilot from constant control pressure.

Pitch stability is indeed about the aircraft's nose moving up and down (pitching) around the lateral axis. So the statement is true.

Answer:

Rotors that sit on opposite sides from one another spin in opposing directions
