t. e. In analytical mechanics, generalized coordinates are a set of parameters used to represent the state of a system in a configuration space. These parameters must uniquely define the configuration of the system relative to a reference state. [1] The generalized velocities are the time derivatives of the generalized coordinates of the system.

The company was founded by electrical inventor William Woodnut Griscom in 1880. An important early customer for electric boat motors was the Electric Launch Company, also known as Elco. Following an 1892 bankruptcy, financier Isaac Rice bailed out Electro-Dynamic and became a co-owner. Griscom died in a hunting accident in 1897.
Fore River Shipyard was a shipyard owned by General Dynamics Corporation located on Weymouth Fore River in Braintree and Quincy, Massachusetts. It began operations in 1883 in Braintree, and moved to its final location on Quincy Point in 1901.

Transport theorem. The transport theorem (or transport equation, rate of change transport theorem or basic kinematic equation or Bour's formula, named after: Edmond Bour) is a vector equation that relates the time derivative of a Euclidean vector as evaluated in a non-rotating coordinate system to its time derivative in a rotating reference frame.
