Here is the LOCKHEED MARTIN F16 Fighting Falcon, Singapore most potent weapon in our air defence.The F16 is very nimble,and its speed and weapon strength is also very strong.Although its design is more than 30years old, it is still one strongest fighter in the worlds air forces inventory.Singapore runs 42 F16C/d BLOCKS 50-60 with a speed of more than Mach 1.

Here is a old mechanism used in
antique clocks like the "cuckoo clock" and "Grandpa"clock.It is extremely complex in design and its is now rarely used due to lack of spare parts.It is not used anymore in "cuckoo clock" but still used in the "Grandpa"clock.

Gears are very versatile and can help produce a range of movements that can be used to control the speed of action.In basic terms, gears are comparable to continuously applied levers, as one tooth is engaging, another is disengaging. The amount of teeth each gear wheel has affects the action on the gear wheel it engages or meshes with.Gears with unequal numbers of teeth alter the speed between the input and out put.

Now let us start on cams.Cams are like small computers as it allows the mechanism to move when a force is applied to the mechanism.It is only limited by its size.The cam must be designed with a smooth edge as the movement will be jammed if designed badly.The Basic principle of the Cam is to turn a circular motion in to one that moves up and down. This is referred to as reciprocating movement.

Let us start on what is a ratchet.A ratchet can be used to move a toothed wheel one at a time.We use a pawl to move a ratchet.A ratchet is used when we want the mechanism to move in only one direction so as to ensure that items like a winding gear will not be dropped.

Basically "automata" is actually a word to refer to our mechanical toys."Automata" comes from the word automaton which means "one that behaves or responds in a mechanical way."Basically the automata simply works just by turning a handle which starts a system of gears,cams,ratchets or any other mechanical parts.

Welcome on board.We shall start the journey.Have a pleasant trip.
