i have a Physic Problem , anyone help !!!

Hi everyone
i work on physics game worked with ipad and iPhone gravity sensor ,
a cylinder on a board , when u rotate the board cylinder must be move on rotation , but when cylinder and board are near together cylinder don’t move on rotation , i must translate the board or cylinder…
how can i fix this problem ?

Your question is hard to understand. When the cylinder and the board are "near together"? The cylinder isn't over the board? My suggestion: post a movie in youtube showing what's happening and post the link here.

No No , Cylinder is Over the board , when i start game and rotate the board Cylinder don’t move !!!?
but when i drop the Cylinder from specific height and rotate the board its work good . i need this but without necessary to drop the cylinder

Have you tried putting a kinematic rigidbody on your board? It seems like the cylinder rigidbody is entering ‘sleep mode’ - see Rigidbody Sleeping. Using kinematic rigidbodies instead of static colliders should solve this problem!

Also, don't post replies to comments as separate answers- it's misleading.
