eLearning Lesson 1 by Tan Zhi Yong(18)

1. Scissors have the lever system, the fulcrum at the joint and the effort at the handles and the load at the blade.
2. Staplers are levers too. The effort is at the ends, when you press the stapler.
3. Paper punchers are levers, the handle is the effort, the linkage is the fulcrum and the part near the fulcrum is the load.
4. The windows have linkages, to make closing of the windows easier.
