Todays i am going to blog about cam profile.


The cam profile is found in many mechanical toys
like the one i showed you in the previous post.




This is how a cam profile look likes











I will now show you how it works in toys


Thats all i have to say for now..

Hello...
Now I am going to show you how mechanism is used in toys


I will show you a few pictures from the net and
explain how it works.


Monkey cam toy



















The monkey will move up and down when u turn the wheel.

A person swimming toy

The swimmer will 'swim' when the axle is turned


Looks good?

So what is D&T? D&T stands for design and technology.

Ok.... Lets talk about Mechanisms.

This are some few examples on Mechanisms terms

LINEAR MOTION - motion in a straight line eg. the motion of a train

ROTARY MOTION - circular motion eg. the motion of a bicycle wheel

RECIPROCATING MOTION - repeating backwards and forwards motion eg. the motion of a piston in a car engine

OSCILLATING MOTION - repeating forwards and backwards circular motion eg. the motion of a clock pendulum

EQUILIBRIUM - a state of balance when both sides are equal

FULCRUM - pivot, a point about which things rotate

LINKAGES - two or more levers connected to produce a desired motion

Now i show you pictures of each example..

LINEAR MOTION

ROTARY MOTION

RECIPROCATING MOTION

OSCILLATING MOTION

EQUILIBRIUM

FULCRUM

LINKAGES

Should be something like that..

OK??

Next...

Hello to the people who is reading my blog now..
This is my first time blogging so i'm not that good...

So.. WHY?!?!? AM I doing this blog??????? Its because this is assigned to us by out D&T teacher and its part of our SA marks too..
Which is kind of threatening...because if you don't do, you will get bad marks and go to a lousy class.
HaHa! Just joking!

OK. No more time to joke. Gotta finsih this quick cause did it at last minute. LOL
