In other words, only 40 per cent, of the applied energy is utilized. 226. An extended series of experiments upon the epicycloidal pulley-block is recorded in Table XII. Ii8 EXPERIMENTAL MECHANICS. [LECT. Vii. TABLE XII. THE EPICYCLOIDAL PULLEY-BLOCK. Size adapted for lifting weights up to 5 cwt. ; velocity ratio 12-5 ; mechanical efficiency 5 ; useful effect 40 per cent. ; calculated formula P = 5-8 + 0-185 # Number of Experiment. R.

It will be seen by the last column that the formula represents the experiments with but little error. 227. Since 60 per cent, of energy is consumed by friction, this machine, like the differential pulley-block, sustains its load when the chains are free.
