Homework Answers
answer is
transverse string + fixed-free BCs as the graph is only matched with the outcomes in this combination and other combinations are not worthy of the result.
AS THE GRAPH WHICH SHOWS THE SINUSOIDAL WAVE IS FORMED IN THE CASE OF TRANSVERSE STRING SO DOES THE OTHER FORMED IN CASE OF FIXED FREE BOUNDARY CONDITIONS.

The rigid body shown below rotates around a fixed axis at O and position angle 0= 0 when the body is in static equilibrium. Force f(t) is applied to the body as shown below. The mass of the body is 12 kg and O is the center of mass. k=1000 N/m_for the spring. Mass moment of inertia I and damping constant c are to be determined. The plot below shows the response 0(t) when f(t) = 60 N is a...
