For those of you who use the IP simulation program: Some of my students
are trying to build a simulation of a rotation problem and having a
problem. The problem involves a vertical long rod, pivoted on the upper
end. The rod swings down and its lower end collides with wad of putty.
It's supposed to stick to the small putty wad, and then the rod and
putty swing up a bit and then temporarily stop. We can't get the putty
and the rod to stick together. I've tried setting the elasticity of
both at 0. Does anyone out there know how to make the two objects
collide and stick together? Thanks.
