what is the max angle the plane can be at so that the crate stays at rest.
static friction coefficient: 0.60
mass of crate: 10kg
max angle of plane: ?

I set it up so that the forces of +mg and -mgUk would = 0. My train of thought was that if they canceled each other out there would be no movement... guess not.
edit: i just realized im not incorporating the frictional coefficient into this, and i might have it a bit backwards. would my positive (downward) force be mg*sin theta and the my negative (upward resistance from friction) force be N*Uk ?
