Hi all,

I'm a beginner under ProMechanism and I try to test this software. I try to simulate the behavioral of con rod crankshaft system. I'm surprised by my first results, the velocity and the acceleration of piston aren't negatives. Do you have an explanation?

I do not know if it is still up to date, but the reason that all values are positive is probably that they are velocity and acceleration magnitudes, not vectorial components regarding a coordinate system.

Thus they can not be negative.
