Practice question · Numerical answer
A sculpture leans until the vertical through its centre of mass reaches the edge of its base. What happens beyond that angle?
Hints
- At that angle the object is on the point of tipping.
- Beyond it there is nothing holding it: set 0 for "it falls".
Show the answer
0
Why
It falls, enter 0. That angle is the tipping angle, and it is the practical measure of stability: a piece with a small tipping angle is one that a passing sleeve will take out, however solid it looks standing still.
