How to stop the motion of a Pivot joint?
I am trying to fix a (8*6)" plastic(poly-carbonate) into another plastic box of size (10*8)".
by drilling a hole at their center and putting a screw through it.
but relative motion b/w the 2 box can't be stopped no matter how tightly i put the screw.
What is the method to stop their relative motion without drilling any extra hole.
