The image depicts the tipping point where the angle of the incline, θ (theta), exceeds ϕ.

An inclined plane: market inertia holds a block in place until a concerted strategy steepens the incline past a critical angle, after which the block tips of its own accord.

Source: Authors' own elaboration.

How to read: The block tips once the incline angle θ passes the critical angle arctan(w/h), where the weight line mg falls through the pivot edge rather than back into the block.
