Sure why not! For the lagrangian I get $$\mathcal{L}=T-V=\frac{1}{2}m(L\dot{\theta})^2+\frac{1}{2}M(L\dot{\theta})^2+\frac{1}{2}k_T\theta^2-(Mgh-mgH)$$ so...

It becomes very trivial, I wanted a different approach :smile:

Summary:: Classical problem about a pendulum! The problem itself: My FBD: I want to solve the problem with vectors, I think that you can use energy principle somehow. If we define the vector ##\vec{O}_B=\begin{bmatrix}0\\ -1\end{bmatrix}## and define a rotational matrix where...
