Question

The nose wheel of a small plane is attached to member AB, which is pinned to the aircraft frame at B. Design a mechanism that will allow the wheel to be fully retracted forward; i.e., rotated clockwise 90°, in t ? 4 seconds. Use a hydraulic cylinder which has a closed length of 0.4 m and, if needed, a fully extended length of 0.6 m. Make sure that your design holds the wheel in a stable position when the wheel is on the ground. Show plots of the angular velocity and angular acceleration of AB versus its angular position 0° ? ? ? 90°, for all designs.
