Gold land, where a gear wheel rolls and hits a fixed ball to activate another device
Material
Corrugated cardboard, Plastic, EVA, Bolt, Nut
Components
Corrugated paper, transparent rod, white rod, EVA washer, Bolts, Nuts
Goldberg connector. When the gear wheel rolls and hits a fixed ball, activate the other device.
It can be used between the B-4 pull switch and the C-1 tongs leg and can also be used in other devices.
You can also easily understand many scientific principles while making a rolling wheel.
1 step. Making a stand
① Fold the two stands along the fold line.
② Fold the two stand supports along the fold line.
③ Assemble the groove of the stand and stand support.
2 step. Making a rail
① Connect the transparent rod to the first hole of stand 1 and the third hole of stand 2.
3 step. Making a gear wheel
① Materials that make gear wheels.
(Assemble in order from left)
② Fit two bolts into the paper washer.
③ Insert the paper washer into the first wheel.
④ Insert 6 paper washers in order of gear wheels-> paper washer and fix with nuts.
⑤ Put the white rod into the completed gear wheel and fix both sides with EVA washer.
4 step. Making a ball fixed board
① Fold the ball anchoring board along the fold line.
Connect the ball fixing board to the transparent bar of stand 2.
5 step. Complete the rolling wheel
① Place the gear wheel inside the stand 1.
(If the EVA washer on the gear wheel touches the transparent rod a lot, the wheel will not roll. Adjust the spacing well.)
② Place the ball on the ball fixed board.
(Make sure the two transparent bars are level)
6 step. Operate the rolling wheel
① The stopper of the pull switch keeps the gear wheels from rolling.
As the pull switch activates, the stopper comes off and the wheel rolls.
② The gearwheel rotates and hits the ball, which leads to the next movement.
