ABSTRACT:
A drum shaft assembly for a drum dynamometer includes at least one annular inertia element on the shaft and releaseably couplable to the shaft and drum to vary the inertia thereof. The assembly carries first interrupted thread means releasably engageable with second interrupted thread means rotatably supported in the inertia element. A manipulator is slideable axially of the drum and shaft assembly between a stand-by position and a working position where it can offer or receive the inertia element to or from the shaft and drum. The manipulator has a support for supporting the inertia element and a rotatable key operable to bring about relative rotation of the first and second interrupted thread means to fasten the inertia element to or to release the inertia element from the shaft and drum.
