How to solve an atwood machine problem
WebThe double Atwood machine is commonly used to demonstrate the effects of classical mechanics, while introducing students to the mathematical concepts of Lagrange. The Lagrangian method makes finding the equations of motion for the masses much simpler than using Newton’s second law to determine the forces acting on each mass. WebHowever, to solve this problem, the proper Langrangian is: L = T − V = 1 2 m 1 r ˙ 2 + 1 2 m 2 ( r ˙ 2 + r 2 θ ˙ 2) − g r ( m 1 − m 2 cos ( θ))) You can find the e.o.m. by solving the Euler-Lagrange eqns.: 0 = ∂ ∂ t ∂ L ∂ r ˙ − ∂ L ∂ r and 0 = ∂ ∂ t ∂ L ∂ θ ˙ − ∂ L ∂ θ. This yields 2 coupled diff. eqns. which you need to solve (e.g. numerically).
