eLearning Lesson 2 by Timothy Lee (25) - Part 2

Part 2

This shows a picture of a simple curtain that has joints on the top to allow us to move it.

The problem with this is that if someone by mistake used a little more force than the little joints can hold, it can/will easily come out and break it.

The solution is the sketch. If there is a pulley system there will not be such a problem.
