A torque is applied to a long thin rod making it rotate with an angular acceleration of 6.70 rad/s2 about an axis through its center and perpendicular to its length (see the Figure (a) below). If the same torque is now applied to make the rod rotate about an axis about one end perpendicular to its length (see Figure (b) below), determine the new angular acceleration of the rod. rad/s2

14. A thin rod (mass lkg and length Im) with its rotation axis perpendicular to its length has a moment of incrtia of 1/12 ML2. Two forces are applied to the rod. The points of application and the directions of the forces are indicated in the diagram below. The orientations of the forces remain constant relative to the rod as the rod rotates and produce a constant torque on the rod. through its centre and Rotation axis (a) If the...
