i have solved a torsional semi-definite system problem.
i have uploaded the solved problem.
solved for modal participation factor and effective mass.
for a semi definite system we know that one of the modes is rigid mode with natural frequency 0.
i think due to the presence of rigid mode I'm getting the modal participation factor vector as [5.3157 -3.76* 10^-3].
is this answer right? i mean how can there be no contribution from the flexible mode?
