What type of lever is lock and key

Expert Answer
The lock and key mechanism is as follows:
- The insertion of the key inside the lock acts like the 'effort' applied to the mechanism from one end.
- The effort applied by the key turns or pushes the cylindrical pins in the lock which acts like a 'fulcrum' at the centre of the mechanism.
- And finally, the load i.e the lock gets unlocked due the pushing of the pins.
This mechanism where in we have the effort and load at the ends and fulcrum in between, indicates that 'lock and key' are the first class levers.
