Problem 3
A structure is idealized as a rigid bar with constant unit mass, ?bar(m), supported by a weightless column
of uniform rigidity, EI, as shown in Figure 4.
Neglecting damping and axial distortion of the column, write the equations of motion for
free vibration in terms of the two indicated degrees of freedom.
a. Use flexibility method for stiffness matrix
b. Us stiffness matrix method
c. Can you find mass matrix?
