Stability against gravitational force

Hi,

I am currently working on a robotic leg model. After designing it i am interested to know that if i place the robotic leg on a table without applying any force on it, will it be stable against gravity or will it topple. More precisely i am interested in simulating stability of design against gravitational force.

Is there any module in SolidWorks that can help me in simulating above mentioned problem.
