The discussion focuses on the challenges of separating centripetal and gravitational acceleration using a dual-axis sensor on a pendulum. The original poster expresses dissatisfaction with their current method and seeks advice from others with experience in this area. They mention researching the Type_linear_acceleration algorithm but are struggling to implement it effectively. Participants are encouraged to share their insights or alternative approaches to improve the accuracy of the measurements. Overall, the thread highlights the complexities involved in accurately distinguishing these types of acceleration in practical applications.

Has anyone got any experience of this using a dual axis sensor on a pendulum? I have attempting to do itt however I am not completely satisfied that my method is successful
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term
##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
