um and whose weight is neglected. A constant friction i^ = 10.5 lbs., acts at the circumference of the journals. It is required to compute the radius of gyration he of the rotating body by the experiment of noting the time t^ occupied by G in sinking a measured distance 5,, from rest. Suppose ^j =… … Fig. 97. while at the same instant the downward linearacceleration j9, = 6a, of G^ enters into the rela-tion involving the sum of downward forces for 6^ as a free body, viz.; O ^ S = mass.
