Extract

The stability criteria for systems whose characteristic equations are of the eighth degree are expressed in a convenient form and a detailed scheme for the computation of the complete set of test functions in sequence is given. A special method for the direct calculation of the critical test function T7 is also given; the vanishing of this determines the critical flutter speeds of quaternary systems.
