Atypical aircraft horizontal tail structure would be capable of carrying torsion moments. a) true b) false

Option b) True

Explanation:

The main purpose of horizontal tail structure in a typical aircraft is to impart stability to the structure and to ensure a straight flying position of the aircraft. It helps in preventing the pitching motion or  up and down motion of the nose of an aircraft nose as a result of the moment created by upward force or lift and downward force due to gravity. The lift or force is applied at horizontal structure at its center of pressure at a distance from the center of gravity of aircraft resulting in the generation of torque.

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.
