WebIn the force ﬁeld, each atom in a molecule is mapped to an atom type representing a chemically distinct environment. A sequence of four atom types i, j, k, and l deﬁnes a dihedral interaction which is modeled by a sum of cosine terms each having a multiplicity, m, a dihedral force ﬁeld parameter km,ijkl , and a phase shift, δm,ijkl ; see eq 1. WebJun 15, 2016 · Since dihedral causes a side force component of lift, you can argue that the outer wing creates more side force which pushes the plane into the turn. But the pilot will compensate the difference in dynamic pressure with the ailerons to stop any rolling motion once the desired turn rate is stabilized. This will also equal the lift on both wings. potsdam thai restaurant
