Unformatted text preview: em will always have an equilibrium state of θ10 = θ 20 = 0 . Using your expressions for T and U above, write down the mass and stiffness matrices for the system corresponding to this equilibrium state. c) Verify that the mass matrix is positive definite. Also, determine the smallest value of the parameter α = K / mgL for which the stiffness matrix is positive definite. Describe in words what you expect the eigenvalues for the system to be for α less than the value found here. You need not actually solve for the eigenvalues. d)...
