, etc., but the lines representing the cohesive forces will be only
of the former lengths. Thus the new
, [Fig. 11], will be laid off from 4 only
of the length shown in the figure.
The relative decrease in the lines representing cohesive forces will be still more marked for a wall
ft. high, the weights of prisms being 400 times as great, but the cohesive forces only 20 times as great as before. It is evident from this reasoning that, for
