Pgiven in equation 20. In order to determine the radius of gyration experimentally,we must first find the radius of oscillation. Suspend the rodfrom the crosshead pin in such a manner that it may swing 58 LOCOMOTIVE OPERATION. freely, and swing it about this center a, Fig. 15, noting theexact time… … Fig. 15. until the point is found v/here the time of oscillation is identicalwith the first test. The distance of this center so found fromthe crosshead pin center is the radius of oscillation, o. Fromthis we can determine the radius of gyration, which is a meanproportional between the radius of…
