The rod AB shown in Figure 3 has a constant angular rotation of 5 rad/s and is advancing upward along the axis of the bolt at a constant rate of 10 mm/s. Express the velocity and acceleration of point A on the rod in terms of its cylindrical components. 10 mm/s 6 = 5 rad/s 100 mm Figure 34
1. In class, we completed three (3) self-experiments concerning angular inertia, radius of gyration, and axis of rotation: 1. We threw the closed Biomechanics book into the air and rotated it about its axis. 2. We opened the book to page 10 and applied a force couple while the book was on the desk and rotated the book through an angular displacement of 180°. 3. We opened the book to the center of the book and applied a force couple...
Determine the moment of inertia of a uniform cube when the rotation axis is along an edge. Suppose its total mass is M=2.5kg, the edges are each 10.0 cm long, it begins at rest, and a constant force, F=4.0N is applied to the edge diagonally opposite the rotation axis. The moment arm and the force are at an angle of 60 degrees. What would its angular displacement from the start be when its angular velocity is 13 rad/s? Draw the...
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...
