I have this exercise:
An extension ladder has a rope, pully, and latch of raising, lowering, and locking the extension. When the latch is locked, the extension is michanically supported and you may safely climb the ladder. To release the latch, you raise the extension slightly with the rope. You may then freely raise or lower the extension. The latch produses a clacking sound as it passes over rungs of the ladder. The latch may be reengaged while raising the extension by reversing direction just at thle latch passing a rung.

Anybody can help me to prepare a state diagram for this . I tried.

best regards

Daniel

 

Go ahead and post your attempt at a diagram. We can then help you sort through any areas that need adjusting.
