“Let the are of the piston a be 20 square inches; of b, 7 sq. in.; of c, 1 sq. in.; of d, 6 sq. in.; of e, 8 sq. in; and of f, 4 sq. in. If... a force of five pounds be applied at c, a pressure of five pounds per square inch will be transmitted in all directions, and in order that there shall be no movement, the required pressure must be applied by all the other pistons in proportion.” —Hallock 1905
