T3 W2:The Journey Continues....

Dear pupils of S206,

Have you submit the assignment, Organise an event in the school hall, to the submit folder?

Using keynote. Define the event, design the activities that are related to the event, take a picture of the layout and write down your considerations when planning the activities and layout of the event. Name the file as NAME_Layout and submit to the ADMT submit folder.

There are two periods today thus a good time to make some decisions. In this architectural design project, you will be given these options:
1. Old SST building,
2. KTM building,
3. KTP Hospital open pond area,
4. Other physical existing building that can be redesigned.

Research on these buildings and their surrounding areas, decide and choose one of the options. Think about how the building can be redesigned and support your ideas with evidences.
Think about this question: " What are the considerations that need to be made before generating idea for your option?"

The followings are some buildings and places in Singapore which are redesigned:

Do research and find out about the history of these buildings and places, Fullerton Hotel, Red Dot Design Museum, St James Power Station and Clarke Quay.
Learn from these examples (What considerations are made when redesigning these buildings and places?) and gather ideas for your architectural design project.

Please remember. Document your work in your journal..... Whatever you did today, it is part of the project journal.

A good WEEK ahead!

eLearning Lesson 2 by Timothy Lee (25) - Part 2

Part 2

This shows a picture of a simple curtain that has joints on the top to allow us to move it.

The problem with this is that if someone by mistake used a little more force than the little joints can hold, it can/will easily come out and break it.

The solution is the sketch. If there is a pulley system there will not be such a problem.

earning Lesson 2 by Ronak (15)

Part 1

1) This is a photo of a fan. The gears inside the plastic hard cover are interlinked and work together at different speeds to get the fan blade moving.
2) This is a photo of a watch. A very commonly used instrument to tell time but is has the same principle, Gears. Turn at different speeds to shows seconds, minutes, hours.
3) This is a photo of a kitchen utensil. It is used to mixed things up. The gears inside work like (rack and pinions), as the handle is turned, the gears that are interlinked will turn at the speed you spin the handle.

E-Learning Lesson 2 Task 2 by Tan Siah Wei (19)

This picture is showing the mechanisms used in a device that winds up towels to rinse the water out of them. Firstly, it has a handle that is slightly detatched from the bar, so that it can rotate independently while in the user's palm. Secondly, there is a small gear, big gear combination for greater power, so the user, who is targeted to be mainly elderly or people who may injure the hands often (housewives) can use it easily. It also cannot be heavy and cumbersome. When the small gear turns the big gear (all concealed inside the metal structure for safety), it will slowly rotate a clip that will be attatched to the cloth, towel. As you can see, there are two clips, on top and at the bottom. These clips have little bumps that actually tilt inwards so that the cloth will not be easily pulled out but can be easily put in (it is still possible to detatch the cloth). For maximum effectiveness, the cloth should be folded such that it is only a few cm wide. As for the length, I will be upgrading it in the near future to have a retractable stand. The base will have a rubber grip on the bottom so that no matter where you put it, it will not slip. It even comes in four different colours! But that's another story for another day.

eLearning Lesson 2 by Abram Tan (01)

Part 1

The first picture is a picture of a ukelele. The ukelele's tuning pegs use gears to allow fine tuning of each string. The combination of gears include a normal gear and a worm gear for rapid gear down with minimal parts. This mechanism is also found in other string instruments, like the guitar. The second picture is a picture of a bicycle. The bicycle has many parts and mechanisms that make it a bicycle, but I would focus on the pedals. These bicycle pedals are used with special cycling shoes which have 'clicks' on them and the pedals have the mechanism that houses these 'clicks'. The main purpose of the cycling shoes is to prevent your feet from slipping from the pedals. It works with the help of a catch, which is attached to a spring. So when cycling, the shoes won't slip or come off unless you turn your foot sideways, releasing the catch. The third picture is of a watch. A watch uses lots of gears to transmit the energy to the hour, minute and second hand. It uses the concept of gearing down to 'slow down the motion of each hand, therefore in a way such that it synchronizes with the day and night, hour and minute.
Part 2

This problem is something to do with the bicycle but not the bicycle itself. Due to little space available, it is pretty inconvenient to keep bicycles in the house. However, risking a stolen bicycle is not worth it.  Therefore, a solution to this space problem is to use pulleys to haul the bicycle to the ceiling, and hang it there.

The alarm clock uses gears to work.

The following above shows a curtain. I figured that it might be a problem as the curtain are high from the ground. So it may become a problem for the young, besides, climbing on things are not very safe. I think levers could do to help this.

Someone would pull 1 down, therefore, 2 will move upwards. therefore "drawing the curtains.

eLearning Lesson 1 by Jonathan Phang (12)

The first picture is a picture of gears used in a bicycle. 

The second picture is a picture linkages used in a chair. When a lever is pulled, the link pushes a part of the chair out and makes it into a comfortable position. 

The third picture is a picture of the pulley system used in blinds. 

Daniel tan lesson 2 part 1

This picture shows a can opener.It uses gears to work. It works by clamping it on a can and then turning the handle which in turn rotates the gear which rotates another gear which is stuck to a cutter. This would enable it to rotate around the can, cutting the lid of the can.

eLearning Lesson 1 part 1 by Brendon Goh ( 07 )

This is a curtain. 

The first image show that the curtain must be manually pulled to close or open. 

It would be better to use a pulley system so that when using force, you might rip it and it can also get stuck easily. 

The sketch shows the pulley system drawn with the curtain. 

This shows that it should be able to last longer.

eLearning Lesson 2 part 1 by Brendon Goh (07)

1) The picture is a reading light. It has a lever to clip the book so it will not fall off. 

2) The second picture is a dust bin that has a linkage to connect to the cover of the rubbish bin so when you step on it the cover will open. 

3) The third picture is a linkage to hold the shelf door open without closing so it is better for people to take things. \

E-Learning Lesson 2 Task 1 by Tan Siah Wei (19)

The first Picture is a washing machine, which uses a pulley system. It has a small pulley powered by a motor, and is attached to a much larger one by a thick "rubber band", which drives the compartment holding the clothes. I could not open the washing machine but you can find the mechanism on the net.

The second and third picture show a compact mini gate. This gate has four parts, jointed by hinges. It is kind of like a linkage, except that it is not fixed to a place, but mobile. The two pictures show how it is used and how it is linked.

The fourth picture is a bicycle brake. which uses two bell crank linkages. When the brake levers are pulled, the cable, linked to the bell crank linkages, will become taut, pulling the top of the linkages upwards and therefore forcing the other end of the linkages onto the rim of the bicycle's wheel. Imagine a scissors. Your fingers are the string, and when you push your fingers together, you force the other end of the scissors to snap together. This is the same, except that you are not cutting the bicycle wheel, but instead forcing brake pads against it.

The fifth, sixth and seventh picture is of the mechanism in a real labyrinth. There are two knobs on the side, which you turn to adjust the plane of the labyrinth. There are two springs, one on either side of the labyrinth. The springs are attatched to a string, which is wound around the axle, attatched to the knob, once, then it joins to the other spring. This will turn the labyrinth either left or right. For forward and backward, there is a frame attatched to the labyrinth by an axle, unattatched to knob. The whole spring, string and axle mechanism is the same. The axles do not cross. They are either above or below the other.

Lastly, it is a piano seat with a compartment. When you lift up the top of the seat, you can clearly see a fixed linkage, where it prevents the compartment from closing on the person's hand when he/she is using it.

Thank You.
