Nov yog kev qhia rau kev tsim cov phom phom marble.

Tsim los ntawm: Erin Hawkins thiab Evan Morris

Kauj Ruam 1: Sau Cov Khoom thiab Khoom Siv

Cov ntaub ntawv:

• 3/4 nyob rau hauv. PVC Yeeb Nkab
• Protractor
• Ob Zip Ties
• Kub nplaum
• Ntoo nplaum
• 3 nyob rau hauv. Caij nplooj ntoos hlav
• Hlau Ntawv
• 16x16 nyob rau hauv. Plywood Square
• 2 3x4 nyob rau hauv. Ntoo Thaiv
• Hlau Pob Khawm
• 3/4 nyob rau hauv. PVC Cap
• 3 Ntsia Hlau

Khoom siv:

• Kub kua nplaum phom
• Lub zog pom
• Laum fais fab
• Clamps
• Txiab

Kauj Ruam 2: Txuas 3x4 Hauv. Ntoo Thaiv Ua Ke Nrog Ntoo Kua nplaum

Cia zaum ib hmo nrog clamps kom cov thaiv tsis txav mus.

Kauj Ruam 3: Txuas Cov Ntoo Txuas Txuas mus rau 16x16 Hauv. Ntoo puag

Siv ntoo nplaum thiab muab tso rau ntawm qhov chaw nruab nrab ntawm lub hauv paus.

Kauj Ruam 4: Laum Pob Khawm Rau Ntoo Ntoo Siv Cov Ntsia Hlau

Kauj Ruam 5: Txiav Slits rau hauv PVC Yeeb Nkab

Txiav qhov hlais ntawm 2.5 hauv thiab 1.6 hauv los ntawm sab hauv qab ntawm cov yeeb nkab.

Kauj Ruam 6: Muab PVC Yeeb Nkab rau Pob Khawm Siv Kub Kua nplaum thiab Zip Ties

Tos kom cov kua nplaum kub kom qhuav. Siv cov kua nplaum kub txhawm rau txhawm rau qhov khoob ntawm cov zauv sib txuas thiab PVC yeeb nkab.

Cov lus qhia Pro: Muab cov kua nplaum kub tso rau sab hauv qab ntawm pob khawm kom ruaj ntseg ntxiv

Kauj Ruam 7: Nqis Tus Kws Lij Choj mus rau Sab Ntawm Cannon

Siv cov kua nplaum kub los tso tus kws txiav plaub hau rau ntawm sab laug lossis sab xis ntawm rab phom nrog nruab nrab ntawm hauv qab ntawm tus kws tiv thaiv kab nrog kab "pob khawm" ib feem ntawm pob khawm.

Kauj Ruam 8: Tsim Lub Vev Xaib Kub Kub

Ntawm daim ntawv siv quav ciab, siv rab phom kub kub los ua lub ntsej muag zoo li cov kua nplaum. Txiav nws kom nws haum rau sab saum toj ntawm lub caij nplooj ntoo hlav (.05 nyob rau hauv txoj kab uas hla)

Kauj Ruam 9: Muab daim nplaum nplaum rau lub caij nplooj ntoo hlav

Siv cov kua nplaum kub ntau dua, tso lub voj voog rau ntawm qhov kawg ntawm lub caij nplooj ntoo hlav.

Qhov no yuav ua rau cov pob zeb tsis txhob poob los ntawm lub caij nplooj ntoo hlav thaum rab phom tau pib.

Kauj Ruam 10: Ntsuas phom ntawm ntau lub kaum ntse ntse thiab ntawm qhov sib txawv kom txog thaum tus qauv nyob deb li cas tau txais

Txhawm rau tua phom, ua raws cov theem no:

• Muab cov ntawv hlau hla los ntawm ob txoj kab
• Muab cov pob zeb marble tso rau hauv rab phom phom (PVC yeeb nkab)
• Thawb lub caij nplooj ntoo hlav mus rau hauv rab phom nrog cov kua nplaum kub lub ntsej muag tig mus rau cov pob zeb ci
• Siv lub hau PVC los txhawm rau lub caij nplooj ntoo hlav los ntawm kev thawb nws mus rau qhov kawg ntawm PVC
• Rub daim ntawv hlau tawm kom lub caij nplooj ntoo hlav tawg tuaj rau pem hauv ntej

Kauj Ruam 11: Vam tias Koj Tau Txais "A" ntawm Koj Txoj Haujlwm

'Nuff tau hais.

Kauj Ruam 12: Xeem

Kev sim_Launch Qhov Siab (m) _ Angle_Distance (m) _ Sijhawm (s) _ Pib Tshaj Tawm (m/s) _

Sim 1 _ 0.22 _ 15 _ 2.0 _ 0.39 _ 5.30 _

Kev sim 2 _ 0.28 _ 30 _ 2.7 _ 0.61 _ 5.10 _

Sim 3 _ 0.28 _ 30 _ 3.2 _ 0.66 _ 5.61 _

Cov laij lej no qhia txog lub sijhawm nws tau siv rau cov pob zeb los tsaws thiab pib qhov nrawm uas rab phom tua. Kev suav suav tseem qhia tau tias rab phom feem ntau zoo ib yam. Txawm li cas los xij, qhov zoo sib xws hauv qhov siab thiab lub kaum ntse ntse, tab sis qhov sib txawv ntawm qhov deb, sijhawm, thiab nrawm rau kev sim 2 thiab 3 qhia tias muaj qhov ua yuam kev thaum tua phom. Piv txwv li, PVC lub hau tsis raug kaw nruj nreem, txo qis lub caij nplooj ntoo hlav.
