changes

okay, so i haven't been regularly posting what i've been doing, my bad

but i've actually done a lot, considering... yeah...

there has been a change of method due to the restriction equipment as some of the equipment could not be found =="

so here's the method with changes made:

1. Cut the plywood into a square 30cm by 30cm and a piece 45cm by 45cm.
2. Drill 4 evenly spaced holes into half of the bigger piece of plywood
3. Attach the 4 7.5cm long compression springs to the smaller piece of plywood
4. Use screws or wood staples to do so.
5. Place the bigger piece of plywood on top of the springs
6. Pull wire through each spring and each hole in the plywood
7. Tie the wire around a bamboo skewer and twist the wire together and cover with duct tape for a firm hold

MORE equipment

so, i've posted two methods, it should make the whole thing work, right?

now, there's the equipment and materials i need for making the earthquake machine,

here's the list of things i need to collect to make the buildings:

1 pack of modelling clay

1 pack of toothpicks (100)

1 pack of uncooked pasta (maybe)

yeah, i think that's it...

THIS SHOULD BE FUN! :D

THIS OR THAT

To Construct the Buildings I have included:

Cube
5. Make a square with the toothpicks by connecting them with 2 cm diameter spheres of modeling clay.
6. Put a toothpick in the top of each ball. They should be forming a 90° angle with the toothpicks on the bottom row.
7. Repeat step 5. Then place this square on top of the toothpicks that are sticking up. This is now a cube.
Tall Rectangle
8. Repeat steps 5-7 two more times.
9. Make three more cubes using steps 5-7.
10. Now put toothpicks in the top of each clay ball on the four higher ones as done in step 6.
11. Now make squares and place them on top of these toothpicks.
Pyramid
12. Repeat step 5.
13. Put one toothpick in each clay ball so that they can be connected at the top with another clay ball.
14. Connect each toothpick at the top with a clay ball. Each side should be a triangle.
Dome
15. Make a hexagon with toothpicks and connect them with clay.
16. Make triangles coming up out of every other 2 clay balls.
17. Connect the top of the triangles so that they form another triangle on top.
18. Repeat steps15-17 twice.

ahh i forgot...

so how can you do an experiment with an aim, hypothesis, variable, constants, method but no equipment? here are the equipment as follow:

20 to 25 71/2 cm compression springs

Duct tape

Staples

Carpenter's stapler

Wire

25 screw eyes

Bamboo sticks

Pliers

Cutting shears

Plywood

Saw

HELLO SRP,

Long time no see...

Aiyah, why are you so annoying? (no offense)

Okay, so I haven't posted anything for like a month D:

I've been having lots of ideas and thoughts with this experiment, but i cant seem to find the words to put down into this blog. It's really stupid sometimes. And sometimes, do you ever get this brilliant idea, but forget it when you're about the write it down? Well, it happens to me, alot.

BUT ANYWAYS,

this is what i've got so far:

Aim: To determine which type of structural design and building would better withstand the effects of an earthquake.

Hypothesis: The structure design that has a base isolator will withstand the most pressure until extremely high levels of strain from the earthquake.

Independent variable: The structural designs of the different buildings being tested

Dependent variable: The time taken for the different model buildings to collapse

Constants: The motion the earthquake simulator creates, The material used to build the buildings and The placement of each building on the earthquake simulator

Method:

1. Collect all equipment, they can be purchased from local hardware store.
2. Cut the plywood into a square 61cm by 61cm and a piece 61cm by 120cm.
3. Drill 20-25 evenly spaced holes into half of the bigger piece of plywood
4. Attach 20-25 7.5cm long compression springs to the smaller piece of plywood
5. Use screws or wood staples to do so.
6. Place the bigger piece of plywood on top of the springs
7. Pull wire through each spring and each hole in the plywood
8. Tie the wire around a bamboo skewer and staple together to have firm hold
9. Twist the wire through the staples and cover with duct tape.

The earthquake simulator is built

This should have been up ages ago...

Okay so I know this was suppose to be up ages ago...

But here it is now:

Aim: To determine which type of structural design and building would better withstand the effects of an earthquake.

Hypothesis: The structure design that has a base isolator will withstand the most pressure until extremely high levels of strain from the earthquake.

Independent variable: The structural designs of the different buildings being tested

Dependent variable: The time taken for the different model buildings to collapse

Constants: The motion the earthquake simulator creates, The material used to build the buildings and The placement of each building on the earthquake simulator
