A balancing act.Classical Mechanics Level 3
With this exercise the instructor is demonstrating which one of these principles?
A. Nothing at all! It is just a very simple exercise that is being used to take up a bit of time. Since the instruction has nothing else planed.
B. Demonstrates that most individuals will have a noticeable difference in the coefficient of friction values between their left hand and their right hand.
C. Demonstrates that many individuals do not have the fine motor skills to actually do this difficult exercise without practicing.
D. Demonstrates a very simple self governing mechanical system with a type of mechanical feedback.
E. Demonstrates that many students are awkward and clumsy and may have difficulty performing even a very simple task.
F. Demonstrates that many surfaces (including a meter stick) may have a natural nap or grain on their surface so that the coefficient of friction is notably greater in one direction when compared then the opposite direction.
