4. 2.1 Generalized Coordinates and Forces . After transforming to generalized coordinates, That is, this implies the basic Euler-Lagrange equations of motion. by assuming that the generalized force 30 Dec 2020 I now introduce the idea of generalized forces. With each of the generalized coordinates there is associated a generalized force.

Other forces are monogenic " Generalized potential! Introduced Hamilton’s Principle! Integral approach! The equations of motion are given by: P = CT λ, or P r =1.λ P θ =0.λ, where λ is the Lagrange multiplier. From (1), ˙r =¨r = 0. substituting into the equations of motion we get: −mrθ˙2 + mg sin θ = λ (3) mr2θ¨ + mgr cos θ =0.

(6.4) Thus, we have the familiar ˙pσ = Fσ, also known as Newton’s second law. Note, however, that the {qσ} are generalized coordinates, so pσ may not have dimensions of momentum, nor Fσ of force. where the Lagrange multiplier term accounts for holonomic constraint forces, and FEXCqi includes all additional forces not accounted for by the scalar potential U, or the Lagrange multiplier terms FHCqi.

Up to the present we have formulated problems using newton’s laws in which the main disadvantage of this approach is that we must consider individual rigid body components and as a result, we must deal with interaction forces that we really have no interest in.

T and V, the potential energy and – If the generalized coordinate corresponds to an angle, for example, the generalized momentum associated with it will be an angular momentum • With this definition of generalized momentum, Lagrange’s Equation of Motion can be written as: j 0 j j j L d p q dt L p q ∂ − = ∂ ∂ = ∂ Just like Newton’s Laws, if we call a “generalized force” j L q ∂ ∂ Derived Lagrange’s Eqn from Newton’s Eqn!
