Inside the printer, there are rolers. As the printer activated,the rolers start to roll so that the paper can go in and come out .This roler is connected with the thick round part which enables the roler to roll. So the roler is wheel and axle.

homework #1

OK, since i am late i'll just give a simple tool: a knife. the knife is classified as a inclined plane as the sides are sloped to create a wedge which we can use to cut with. the smaller the angle of the inclined plane, the sharper it is.

        

Simple machines.

Okay I just woke up so this isn't the best piece of work I can make. Sorry for the late post... I've been very busy in Jkt. The simple machine I'm going to write about is the lever. The item? Tongs. It's fulcrum is at the end and the effort in the middle. Load is at the other end. To make it simple it's like this : LEF... Now, as the load moves over a larger distance than the effort and since the action occurs at the same time, the load actually moves faster. Okay, I forgot to add ONE point. This type of lever is actually the third-class lever. In third class levers, effort is applied between the load on one end and the fulcrum on the opposite end. How does these tongs make our lives easier? Well, it helps to not pick up rubbish by your hand, put coal in the barbecue grill or even take it out. In simple, the tongs helps us by picking up and gripping things. The few of the many types of tongs are:  sugar-tongs, asparagus-tongs,  blacksmith's tongs and crucible-tongs.

Note: Okay... this is sooo not my style of writing... I'm like a buisnesswoman with no sense of humour.... sorry.

Homework 1 ONE uno wha'dya want?

First, a fan screw. Its used on a fan to adjust how high you want it 2 be. A fan screw is an inclined plane.With its big 'head' you can turn it more easily compared to your average screw.

Above is a pic of my ye olde GBA SP.( Its only there coz the Blogger system stubbornly refuses to put the pic at the bottom)There is a gear at the little blue circle just below the top section(you see it? its right there...........)The gear is used for flipping the top section.

Simple Machine

1.Spoons and Fork.They belong to the lever category of simple machines.The fulcrum is in the middle while load and effort are infront.Fulcrum is something that the object lean on , in this case,our hand.Our index finger and thumb hold the spoon/fork which will be the effort while the load is ,of course,our food.

2.I don't know what exactly it is called,but i draw it,looks quite blur but never mind.

I have also draw out where the wheel and axle are.When we turn the axle which is also the handle,the wheel will turn and garden hose will extend by rolling out more and more .Since the axle (where effort is apply)travel a longer distance than wheel,it reduce effort .

3.Chopstick,i know Wei Jie had done them but it is the first i idea i have come up and i have written a lot notes on them,so i decided to put it in anyway.

Chopsticks itself is not really a lever,but when we use it,it can be consider as a lever.(had check with tuition teacher)When we use the chopsticks, the fulcrum is in the middle while effort and load is infront.This type of lever involve a larger effort to move them load ,the effort and load also move in the same direction.Take a pair of chopsticks and try this to see if it is really a lever.The middle part of chopsticks leans against in between your thumb and index finger which will be fulcrum while effort is apply by your fingers.The load,of course,is your food!

So this is a simple machine that is not really a simple machine.It is only a simple machine when we use it,and not a simple machine when it is not in use.

homework1 (science)

The fixed pulley
Some curtains use a fixed pulley to open and close the curtain. It is of great help as it changes the direction of a force, making it easier to open and close a curtain, and also the distance moved by the effort is same as the distance moved by the load. So whenever you want a curtain open ,just pull the string that is attached to it.

my door knob its has a wheel and axle inside like there are two axle and one wheel and the axle is coverd by the knob so when u turn the knob or push it down the wheel in the middle will mover henceforth opening the door.(iam not sure if my explanation is detailed...^-^)

another wheel and axle is the clock on the wall the axle is smaller than the wheel in diameter.The axle is in the clock , in the concealed part.

a lever is a crowbar. I dont know why is it in my house but its just in there.when we use it to open crates that are tightly sealed during that moment the crowbard is counted a lever. by the lucky the minituare schnauzer .

homework 1

1. The switch, is an everyday tool that we use. And, the simple machine that is used is the lever. The fulcrum is in the middle of the switch while the effort is on the side of the switch while the load is...to turn the switch on!

The lever helps us by reducing the amount of effort needed for the job or or it can move the load a longer distance depending on where the fulcrum is.

2. The door stopper is a very effective simple machine that is used to prevent the doors from moving. It is actually an inclined plane that is wedged right between the floor and the door which in turn, will prevent the door from moving!

3. The can opener is a ingenious device that allows you to open up your cans with ease. It has gears inside which turns the blade inside when you turn the handle.

4. there is a type of ceiling fans that need you need to pull some string to change the speed which, uses pulleys!!When you pull the string, you also pull something inside the fan to change the speed!

the three days at school

during the first three days at school we spent the first day at school doing english we played games and did some work like doing each others compo.the second day is maths, we did some challenging questions with our teamates and finally the third day we spent time doing science we did many experiments and had a great class party bash at the end of school.we had so uch fun during the three days at school during the holidays.

I took this picture from the internet.The chopsticks is a lever.The point where two chopsticks crossed is the pivot of the lever.In ancient times, our ancestors liked to steam or boil food. It was difficult for them to use spoons to dip vegetables in the soup.So they invented the chopsticks as it is easier for them to use it to dip vegetables.We hold the chopsticks with our thumb, index finger, middle finger and third finger. One stick is against your third finger and the other leans on your middle finger.When we pick the food, we use our index finger and middle finger to control the chopsticks and nip food.It will be hard to keep using spoon if they did not invent it.
