The rod is disturbed slightly and falls to the right. Using the angle \( \theta \) between the ground and rod as your generalized coordinate, derive the equations of motion using both the Newton-Euler approach ( \( F=m a) \) and Lagrange's equations.
WebThe Lagrangian L is defined as L = T − V, where T is the kinetic energy and V the potential energy of the system in question. Generally speaking, the potential energy of a system depends on the coordinates of all its particles; this may be written as V = V ( x 1, y 1, z 1, x 2, y 2, z 2, . . . ). WebThe Euler–Lagrange equations can also be formulated in terms of the generalized momenta rather than generalized coordinates. Performing a Legendre transformation on …
