Hi,

I've got a simple SimMechanics problem. I have a body connected to a revolute actuator. I'm applying a constant angular acceleration to the joint using a joint actuator, then I am measuring the actual angular acceleration of the joint using a joint sensor.

It turns out that the applied angular acceleration and the measured angular acceleration are off by a large factor. Why?? Why aren't they the same? I would have expected them to be the same value. Any help is greatly appreciated.

Thanks,
Greg
