5. Three disks and a driving wheel are connected by shafts, Fig. 34.99. The right end disk is free. Each disk has the same moment of inertia I, and the three shafts have the same torsional stiffness constant, k. Set up the system of differential equations for the angular motion 0:0), 82(0), 63(6) of the three disks from their equilibrium positions due to an angular motion of the driv- ing wheel. Assume that initially the disks are at rest and...

Figure shows a disk with moment of inertia J=0.5 kg-m2 that is initially rotating at an angular velocity 0 0 = 40 rad/s. A flexible shaft with torsional spring constant k = 65 N-m/rad connected to the disk. The disk is subjected to friction, which is modeled by linear viscous friction torque bò, with friction coefficient b = 1.0 N-m-s/rad. The input torque in the clockwise direction is a step function Tin(t) = 3.0U(t) N-m. Flexible shaft, k Disk Viscous...

Problem 1 Two identical pucks, each of inertia m, are connected to a rod of length 2r and negligible inertia that is pivoted about its center (that is, there is some sort of pin though its center, around which it can rotate without friction). A third puck of inertia m/2 strikes one of the connected pucks perpendicular to the rod with a speed vi. Assume the collision is elastic. (a) Draw a diagram of the situation, clearly labeling the direction...

Problem 1 (40 points) The rotational system shown in this diagram has a single torque input, T(t), and a single angular displacement output, (t). Also shown are the shaft polar moment of inertia, J, torsional spring constant, k, and rotational viscous damping coefficient, c. From the law of rotation (sum of the moments equal to polar moment of inertia times angular acceleration), we obtain: jä(t) + c)(t) + ko(t) = T(t). This ordinary differential equation is second-order, linear...

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...
