 States that for any given pressure (P), the tension (T) developed by the ventricular wall increases as the radius (R) of the cylinder increases.For a cylindrical vessel T = P × R.For a spherical vessel T = (P × R)/2.So for any given radius and internal pressure, a spherical vessel will have half the wall tension of a cylindrical vessel.

 In the case of the heart, the left ventricle has a much greater radius than the right ventricle and thus is able to develop greater tension (or force).
