Omitting w and neglecting the small variation of the specific heat of the liquid, the result is simply the addition of the term (**c-b**)/V to formula (23) log p=A+B/B - I - C log B-f-(**c-b**)IV..

For if in the triangle abc the side ab is taken so as to represent on a given scale the tension of the surface of contact of the fluids a and b, and if the other sides be and ca are taken so as to represent on the same scale the tensions of the surfaces between b and c and between c and a respectively, then the condition of equilibrium at 0 for the corresponding tensions R, P and Q is that the angle ROP shall be the supplement of abc, POQ of bca, and, therefore, QOR of cab.

If the load rests directly on the main girder, the greatest -Iand - shears at C will be wXAGC and -w X CHB.
