eLearning Lesson 2 by Nur Shamemi (03)

The first one is a chair with a lever to pull when we want to adjust the height of the chair, whether it being up or down.

The second picture is of a handle to open a window, with the application of the wheel and axle, where we would have to turn the handle to a point and pull to open the window.

The last one is the door hinge for a cabinet, where the linkage connects the cabinet and the door.
