Generalized forces. In analytical mechanics (particularly Lagrangian mechanics ), generalized forces are conjugate to generalized coordinates. They are obtained from the applied forces Fi, i = 1, …, n, acting on a system that has its configuration defined in terms of generalized coordinates. In the formulation of virtual work, each ...
Category. v. t. e. Mechanics of planar particle motion [1] is the analysis of the motion of particles gravitationally attracted to one another observed from non-inertial reference frames [2] [3] [4] and the generalisation of this problem to planetary motion. [5] This type of analysis is closely related to centrifugal force, two-body problem ...
Classical mechanics. The relative velocity, denoted (also or ), is the velocity vector of an object or observer B in the rest frame of another object or observer A . The relative speed is the vector norm of the relative velocity.
In fluid dynamics, the Stokes stream function is used to describe the streamlines and flow velocity in a three-dimensional incompressible flow with axisymmetry. A surface with a constant value of the Stokes stream function encloses a streamtube, everywhere tangential to the flow velocity vectors. Further, the volume flux within this streamtube ...
Energy minimization. In the field of computational chemistry, energy minimization (also called energy optimization, geometry minimization, or geometry optimization) is the process of finding an arrangement in space of a collection of atoms where, according to some computational model of chemical bonding, the net inter-atomic force on each atom ...
Axes conventions. Heading, elevation and bank angles (Z-Y’-X’’) for an aircraft. The aircraft's pitch and yaw axes Y and Z are not shown, and its fixed reference frame xyz has been shifted backwards from its center of gravity (preserving angles) for clarity. Axes named according to the air norm DIN 9300. In ballistics and flight dynamics ...
Types. There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.
12 VLS tubes, four 21 inch (530 mm) torpedo tubes for Mk-48 torpedoes BGM-109 Tomahawk. USS Vermont (SSN-792) is a Virginia -class nuclear powered attack submarine in the United States Navy. She is the 19th boat of the class and the third vessel of the Navy to be named for the U.S. state of Vermont. Then Secretary of the Navy, Ray Mabus ...
