The primitive active power of a substance, Leibniz tells us, is "a nature or an internal force that can produce in it, in an orderly way all the appearances or expressions it will have, without the help of any created being" (New System GP iv 486/AG 1486/AG
In 1976, U.S. Adm. Hyman G. Rickover's private investigation concluded that the explosion was caused by an internal force, likely a fire in the coal bunker.
Experiments on pellicles, or floating biofilms, of Bacillus subtilis showed that while they are multiplying and secreting extracellular substances, bacteria create an internal force (associated with a −80 ± 25 Pa stress) within the biofilms, similar to the forces that self-equilibrate and strengthen plants, organs, and some engineered buildings.
Numerical examples are presented in terms of contours for the extended displacement and stress fields in a three-layered MEE half-space made of piezoelectric and piezomagnetic layers induced by an internal force and dislocation applied over a horizontal circle.
But Putin has an alliance with Bashar al-Assad, who regards Isis as an internal force that must be destroyed.
White women continued to make inroads based on increased access to professional and managerial occupations, including human resource departments of major corporations, where they became an internal force for change.
Such changes would be due to an "internal force".
However, the literature reports that an internal force arises when fatigue tests are performed inside pressurized vessels, acting directly on the vessel shaft.
In the plastic phase, the adhesive develops a uniform stress distribution along the overlap length, thereby enabling sufficient joint rotation to provide an internal force redistribution that increases structural safety and robustness.
The robots exert an internal force to spin and then connect with each other using magnets, allowing them to fly into the air for a second and then fall down next to their brothers and sisters in exactly the right spot.
