MATLAB: Composite Force returns three signals

Question

Hi everyone,

I am trying to measure the force applied to a Revolute Joint in a Simscape Multibody system. To do this I have selected Total Force in the Composite Force/Torque Sensing tab. Based on this page: https://es.mathworks.com/help/physmod/sm/ug/sense-internal-forces-in-double-pendulum-link.html. it should return the axial and longitudinal force, but it returns three data columns. So, to which force corresponds the third data column? I guess it is the total force, but I am not sure…

Thanks.

Answer 1

I have just realised that each column corresponds to a xyz axis, which direction is defined by the Base Coordinates of the Revolution Joint that we are analizing.
