Concept explainers
A flight simulator is used to train pilots on how to recognize spatial disorientation. It has four degrees of freedom and can rotate around a planetary axis, as well as in yaw, pitch, and roll. The pilot is seated so that her head B is located at r = (2 ft) i + (1 ft) j with respect to the center of the cab A. The cab is rotating about the planetary axis with an angular velocity of 20 rpm counterclockwise as seen from above, and this is increasing by 1 rad/s2. Knowing that the cab rolls with a constant angular velocity of (−4 rad/s)i, determine (a) the velocity of the pilot’s head, (b) the angular acceleration of the cab, (c) the acceleration of the pilot’s head.

- Two squirrels are sitting on the rope as shown. The squirrel at A has a weight of 1.2 lb. The squirrel at B found less food this season and has a weight of 0.8 lb. The angles 0 and > are equal to 50° and 60° respectively. Determine the tension force in each of the rope segments (T₁ in segment, T₂ in segment Я, and T3 in segment DD) as well as the angle a in degrees. Ө A α B Note the figure may not be to scale.
