Steve,
Is there a way to model pulley cable friction?

Hi Steve, fantastic example!

I've been trying to use your sm_block_and_tackle example as a basis for a problem involving three blocks-and-tackles lifting a tray-like load. Do you have a suggestion on how to model the joints between the tray-like load and the three blocks-and-tackles? Spherical joints trigger the error "kinematic constraints cannot be maintained". Real-world experience suggests the tray-like load should be capable of all yaw, pitch and roll (i.e., 3 degrees of freedom), under the pull of the three blocks-and-tackles, so there should be a way to model it.
