Pascal's principle as it applies to pistons to solve the force
problem. The equation to start with is the pressure equivalency
equation:![](/sites/dl/free/0098458137/193800/eq_pascalPiston.gif) (0.0K).

forward equals the pressure generated by the sides of the caecilian.
Substitute in the definition of pressure and solve for forward
force, Ff. | | ![](/sites/dl/free/0098458137/193800/ch13_answer1.gif) (1.0K) | | The
force is not all that large. However, because the volume of
the caecilian needs to stay relatively constant, there needs
to be a large expansion in lengthwise direction. | | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) |
