b. [20 points) Starting with the assumed values, write down the mass matrix [m] and the stiffness matrix [k]. Using the flexibility influence coefficients from example 6.5 compute the influence matrix [a]. Use [m] and [a], compute the Dynamical Matrix [D] for the system. No need to write the (c) matrix. C. (20 points) Using A = 12[1]-[D]I = 0, derive the Characteristic Determinant of the system. (Hint) it will be a 3 by 3 matrix in terms of a, where a = mo?/k. No need to compute the characteristic polynomial or its roots.
