Lagrangian of simple pendulum
Tīmeklis2024. gada 10. marts · Schematic of a planar double pendulum. We can obtain the equations of motion for the double pendulum by applying balances of linear and angular momenta to each pendulum’s concentrated mass or, equivalently, by employing Lagrange’s equations of motion in the form (1) where the Lagrangian … TīmeklisThis Demonstration uses Lagrangian mechanics to compute the equations of motion of the disk and the pendulum and to plot the trace of the pendulum bob. [more] A horizontal energy gauge shows the total energy of the system, which remains constant while the potential energy and kinetic energy change in opposite directions.

TīmeklisExpert Answer. 5. Using the Lagrangian method, derive the equation of motion for the simple pendulum shown in the figure. Calculate the natural frequency of the pendulum. θ < 10∘,L = 0.2 m, m = 10 kg. TīmeklisThe area under the curve is obtained by integration, A = ∫ ydx, which we write as. A = ∫π 0y(s)dx ds ds. We can replace the factor dx / ds by √1 − y′2, where y ′ = dy / ds. This gives us, finally, A = ∫π 0y√1 − y′2ds. We wish to find the function y(s) that produces the largest possible value for A.
