'r' is the position of the centre of gravity of all parts of the vehicle minus the excavator arm itself (chassis, cab, outriggers, wheel and front bucket). None of these parts will move when the boom is fully retracted so the position of 'r' remains unchanged as the geometry of the excavator arm changes. I hope this helps.

Can you tell me if machine CG 'r' has to be checked @ Boom fully retracted condition?
