The coefficients of static friction are the same for both cases. As we can see from the animation, the low-applied force slips before it tips, whereas for the high-applied force, the block tips first.
The reasons for this 'renaissance of friction' are the development of highly sensitive experimental tools, such as friction force microscopes ... of transition from static to kinetic friction ...
The amount of twisting, measured by the displacement (x) of the tip from its resting position, reveals the magnitude of the friction force. The normal force (FN) controls how hard the tip presses ...
