A bstract — The interaction of capsule length and oscillation amplitude has been studied in detail both empirically and theoretically. The previously reported optimum ratio of length: amplitude of π/2 was shown to be incorrect; that value in fact coinciding with a minimum in efficiency. Optimum performance was found to occur for that ratio lying in the range 0.5–1.3. The use of the performance criterion “success time” was shown to be effective in the study of such problems, and can thus be used as a basis for direct investigation of a number of mechanical amalgamation variables.
