MATLAB: Can’t simulate simple lever in SimMechanics

fulcrumleversimmechanicsSimscape Multibody

It is very simple mechanism, but I can't define fulcrum in O point. I have created 2 bodies and connected them by weld. Then I created new CS3 in body AO, and tried to connect with Revolute block, but model didn't work.

You just need two bodies, one for AOB and another one for the second body starting at B. You just need to define the appropriate CS on the first body and have a revolute joint to ground from there. Have a look at the following snapshot:

CS1 is the pivot point.
