1. A shaft system comprising:
an outer shaft including an outer surface and an inner surface defining a conduit;
an inner shaft extending within at least a portion of the conduit, the inner shaft including a radially extending passage having a first end and a second end that is opposite the first end; and
a centrifugal force activated damper extending between the outer shaft and the inner shaft, the centrifugal force activated damper including:
a first member arranged between the inner shaft and the inner surface at the first end of the radially extending passage;
a second member arranged between the inner shaft and the inner surface at the second end of the radially extending passage; and
a connecting member extending through the radially extending passage, the connecting member including a first end section connected to the first member and a second end section that is received by the second member, wherein rotation of the shaft system causes the first member and the connecting member shift away from the second member into the inner surface of the outer shaft.
