The FALKIRK WHEEL.
Soalan: Bagaimana hendak menghubungkan 2 terusan yang tidak terletak di paras yang sama serta memudahkan bot dan kapal untuk belayar tanpa sebarang gangguan?
Jawapan: Bina Falkirk Wheel, di Glasgow, Scotland.
This is a good and excellent engineering design.
When the connection between two Scottish canals was disconnected, a clever solution to reconnect them was employed. Instead of linking them by a series of locks, a giant rotating wheel was constructed to lift and lower the boats the 79 feet from one canal to the other.
These caissons always weigh the same whether or not they are carrying their combined capacity of 600 tonnes (590 LT; 660 ST) of floating canal barges as, according to Archimedes' principle, floating objects displace their own weight in water, so when the boat enters, the amount of water leaving the caisson weighs exactly the same as the boat. This keeps the wheel balanced and so, despite its enormous mass, it rotates through 180° in five and a half minutes while using very little power. It takes just 22.5 kilowatts (30.2 hp) to power the electric motors, which consume just 1.5 kilowatt-hours (5.4 MJ) of energy in four minutes, roughly the same as boiling eight kettles of water.
Obviously for mechanical engineers, the challenge is to design and develop power transmission systems using gears .... untuk angkat bebanan dari bawah ke atas dan sebaliknya.
For EE engineers, the challenge is to design the communication system from the control room to the actual machine.

Sama-sama kita perhatikan satu pencapaian kejuruteraan yang hebat.
Inilah yang kita harapkan pelajar2 JAD boleh menyumbang sesuatu untuk kebaikan rakyat Malaysia.
Selamat Berjaya dalam exam.
