where 



io = coefficient of angular rotation. 



w = weight. 



a = weight of forearm. 



x = distance of centre of gravity of loaded forearm from 



centre of elbow joint. 

 t - time in seconds, until fatigue sets in. 



No. i*— Myself. 



x - 8.2 in. w = 8 lbs, 



a = 3.75 lbs. t - 480 sees. 



Total work in ft. lbs. = 3854 w. 



No. 2. — Dr. Foot. 



x = 8.2 in. w = 8 lbs. 



a = 3.5 lbs. t = 360 sees. 



Total work in ft. lbs. = 2829 w. 



No. 3. — Captain Haughton. 



x = 8.38 in. w = 9 lbs. 



a = 2.94 lbs. t = 720 sees. 



Total work in ft. lbs. = 6003.3 (0 - 



No. 4.— Mr. M. H. Ormsby. 



x = 8- 27 in. w = 9 lbs. 



a = 3.25 lbs. t = 555 sees. 



Total work in ft. lbs. = 4685.4 to. 



* In all these experiments, the weight was suspended at a distance of 9 inches 

 from the centre of the elbow joint.
