3-7 Practice with Free-Body Diagrams
... The free-body diagram of the elevator is a bit more challenging. Let’s start by drawing a downward force of gravity and an upward tension force, which are the only forces that act on the elevator when the elevator is empty. Even though we draw what looks like an empty elevator, to construct the free ...

Lecture 29: Friction Examples
... Reasonable?: Woah! This is not only much bigger than my guess, it is bigger than 1! This would mean that it requires less force to pick up the entire Porsche and move it to one side than it does to push it along the ground starting from rest. Research → Apparently, yes! This is the sort of number yo ...
