The figure below shows a landing gear mechanism for a light aircraft. The weight of the wheel is estimated approximately as 100 lb. Thus it is required to implement a motor capable to lift this weight during the retraction and extraction. The radius of gyration has been determined experimentally as 1.2 feet. In order to achieve a safe operation, a motor is selected adequately with an angular velocity of 3 rad/s, and an angular acceleration of 10 rad/s.
