Next, we specify the quantities Q a ( q ) to be the generalized time-dependent Kepler potential V = − ω ( t ) r ν and determine the functions ω ( t ) for which QFIs are admitted.

A NOTE ON GRASHOF THEOREM - NTOU

WebThe Grashof theorem provides the basic condition that the four-bar linkage must satisfy so that at least one link completes a full revolution. According to this theorem, a four-bar linkage contains one or more crank links if the combined length of the shortest and longest links does not exceed the combined length of the two remaining links.
