A thin rod (m=0.3 kg, L=0.6m) is hung from a thin wire. The wire is attached to the rod so that it is balanced horizontally. The rod is then given an angular displacement of 2 revolutions and then released from rest. Given that the rod takes 1.6 seconds to move through 1/4 cycle, determine the torsional constant for this oscillator. Assume no energy loss due to friction.

A. 0.042 Nm

B. 0.011 Nm

C. 0.019 Nm

D. 0.009 Nm

E. 0.061 Nm

    The hammer throw is an Olympic event where a 7.5 kg metal ball is attached to a 1.2 m long wire, as shown in the diagram. One such competitor was observed to swing the hammer around in a horizontal circle with an average angular acceleration a = 5.6 rad/s?. After 3 seconds the hammer was released. (a) Calculate the angular velocity and tangential speed of the metal ball just before it is released. (b) Calculate the number of revolutions the...

    A hollow, thin shelled sphere of radius rK=0.08 m and mass mK=1.8 kg is attached at one end to a rod of mass mS=mK and the length L=5?rK. The sphere-rod system can pivot without friction about a horizontal axis at (A),from its equilibrium angular position, and then released. A. After what time does the sphere reach the highest point on the right for the first time? t= 0.653 s B. Determine the speed of the sphere when it pivots through...

    A spring stretches 0.150 m when a 0.300 kg. mass is hung vertically from it. From this information you can determine the spring constant, k. Next, the spring is set up horizontally with the 0.300 kg. mass resting on a frictionless table. The block is pushed so that the spring is compressed 0.100 m from the equilibrium point, and released from rest. Determine: The spring constant k (in N/m)? The amplitude of the horizontal oscillation (in m)? The angular frequency,...

    1. A thin rod of mass M and length d hangs vertically from a frictionless pivot attached to one end. A piece of clay of mass m moving horizontally at a speed v hits the rod a distance x from the pivot and sticks to it. Discussion Questions: (In the first 5-10 min a random group will be selected to explain.) • What “type” of collision is happening? What is and is not conserved? • Consider the analogous linear momentum...
