(T = \frac12 m_1(\dotx_1^2+\doty_1^2) + \frac12 m_2(\dotx_2^2+\doty_2^2)). For small angles, (\sin\theta\approx\theta,; \cos\theta\approx 1-\theta^2/2), and keep up to quadratic terms in (\theta,\dot\theta).

This collection contains in Lagrangian mechanics, ranging from fundamental applications (simple pendulum, harmonic oscillator) to intermediate systems (double pendulum, bead on a rotating wire) and advanced topics (Noether’s theorem, small oscillations, relativistic Lagrangians).

– The wedge accelerates leftward (negative ( X )) while the block slides down. In the limit ( M \to \infty ), ( \ddot X \to 0 ) (fixed wedge), and the block’s acceleration becomes ( g\sin\alpha ), as expected.

This problem illustrates how fictitious forces appear without explicit mention.
