By 1800 each of these areas also had an extensive plateway system depending on gravity-induced movement or animal traction.
There is no vertical control (solely depended on gravity and wind).
When the pump is operating, the sap will run under what would be marginal conditions, like colder daytime temperatures, for systems that just depended on gravity.
Trip-hammers depend on gravity for their impulse, but steam hammers often employ, in addition to gravity, a downward thrust from a steam-activated piston.
The results show that the process of bubble formation and detachment depends on gravity, the orifice diameter, the gas flow rate, and the liquid cross-flow velocity.
The find--20,000 light years from Earth--is the result of a technique called gravitational microlensing, which depends on gravity's ability to bend light.
Using knowledge of how the flow of materials in landslides on Earth depends on gravity, Dr Vincent is examining the slopes across the surface of Lutetia to try to measure the local gravity.
Steven Collins of the University of Michigan, Ann Arbor, and colleagues showed off several robots that use a "passive-dynamic" control system involving simple actuators and motors to create an energy-efficient gait that depends on gravity.
"What about the systems that depend on gravity like your muscles, or your balance system, or your heart and blood vessels?" There is good reason to believe the human body would develop differently.
Inspection of the first Eq. 1 reveals that the roll rate depends on gravity and centripetal acceleration (1st row), the gyroscopic effect (2nd row), and tire cross section (3rd row).
Because a normal pen depends on gravity to produce the flow of ink, an alternative was needed for the moon missions.
