Dab tsi yog thawj lo lus nug nug rau tus neeg uas mus zaum rooj pob zeb? Yog lawm, qhov no yog "koj nias ntau npaum li cas." Qhov nrov ntawm cov lus nug yog vim qhov tseeb tias lub rooj zaum xovxwm tshuab yog feem ntau muaj thiab nrov npe. Yuav ua li cas ua tus projectile rau kev coj ua tom tsev?
Kev npaj qhov kev npaj
Lub rooj ntev zaum yuav tsum ua cov tswv yim, txhim khu kev qha thiab me me ntawm qhov loj me. Qhov zoo tshaj plaws yuav yog kev ntseeg tau, vim tias ua haujlwm nrog cov huab hwm coj loj tuaj yeem tsoo nws. Qhov tseeb, cov no yuav tsum yog tej daim loj loj ntawm hlau hlau ua ke.
Tom ntej taw tes yog qhov ntev. Txij li thaum lub khauj khaum zoo li yuav nyob hauv chav tsev, nws yog qhov tsim nyog yuav tsum tau ua kom nws ntog. Cov qauv ua tiav tau tuaj yeem sib dhos thiab rhuav tshem, thiab tom qab ntawd yuav tsis muaj teeb meem cia khoom.
Cov ntaub ntawv dab tsi xav tau los npaj
Nws yog qhov zoo tshaj plaws los coj tus pas hlau profile rau lub rooj ntev zaum - koj tuaj yeem yuav nws hauv khw muag khoom kho vajtse. Muaj ib lub xwmfab thiab duab plaub, tab sis ib lub xwm fab ib haum rau lub rooj ntev zaum. Kev sim sim tuaj yeem tsim los ntawm cov yeeb nkab ntawm tib yam thiab loj. Qhov profile loj yog 40 los ntawm 40 millimeters, thiab cov tuab yog 2 millimeters.
Koj kuj yuav tsum tau coj ob lub voos xwmfab hlau nrog tuab ntawm tsawg kawg 5 millimeters. Lawv yuav mus rau tus tuav tus pas, yog li ntawd lawv yuav tau khoov rau hauv cov nqai.
Cov khoom kawg los npaj yog cov ncoo roj hmab, txiv ntoo thiab bolts. Txij li tag nrho cov qauv yuav ua los ntawm cov hlau, cov ntsiab lus roj hmab yuav tsis tsuas yog pab ua kom lub projectile tsis muaj suab nrov, tab sis kuj tiv thaiv nws los ntawm kev txhuam hauv pem teb. Tsis tas li ntawd, cov ntaub qhwv yuav ua rau lub projectile seem ruaj khov.
Ib qho kev ua haujlwm zoo tib yam, leatherette thiab ua npuas roj hmab yog qhov tsim nyog rau lub rooj zaum. Ib tug lounger ua los ntawm cov ntaub ntawv yuav txawv los ntawm kev nplij siab, kev ua tau zoo thiab elasticity. Lub projectile yuav sawv ntawm 3 qhov kev txhawb nqa, qhov ntev yog 1 meter, thiab qhov siab yog 80 centimeters.
Txheej txheem ntawm kev tsim
Nws yuav tsum raug sau tseg tam sim ntawd tus qauv tsim yuav ntxig me ntsis. Lub projectile creation algorithm yog raws li nram no:
- Ua ntej koj yuav tsum txiav lub bar ntev, thiab tom qab ntawd koj yuav tsum pib vuam.
- Ob txoj kab txiav sib tshooj yuav tsum tau txuas rau ob kab tuav txoj kab.
- Mus rau lwm yam khib - ib lub laj thawj txiav.
- Ntawm cov kab, koj yuav tsum ua qauv tawm ntawm qhov siab ntawm 340 centimeters. Nws tsuas yog nyob ntawm no tias qhov kab rov tav ntawm txoj kab rov tav yuav tsum tau welded rau cov profile.
- Qhov tseeb hauv nruab nrab, ib txoj kab ncaj nraim yog welded rau kab rov tav, khiav mus tib seem rau hauv pem teb. Lub rooj ntev zaum yuav nyob ntawm nws.
Qhov no ua tiav vuam ua haujlwm, thiab koj tuaj yeem txuas mus rau hnub poob. Txhawm rau kom ruaj ntseg nws, nws yog qhov tsim nyog los ua 3 lub qhov hauv qhov nqaj txhua 30 centimeters. Tib qho txheej txheem yuav tsum tau ua nrog plywood. Cov pawg yog fastened nrog bolts. Cov roj nplaum ua npuas yog txhawm rau saum, thiab tom qab ntawd txhua qhov no yog them nrog tus hloov pauv.
Ntawm qhov no, kev tsim cov qauv rau cov xovxwm raug tshem tawm tuaj yeem suav tias yog ua tiav - txhua yam uas tseem tshuav yog kom tau qhov barbell los yog ua koj tus kheej, thiab tom qab ntawd ua nws pub dawb hauv tsev. Yuav muaj lub siab xav - thiab koj tuaj yeem ua qhov sim pheej yig rau koj tus kheej. Qhov kev xaiv no haum rau txhua tus neeg uas xav xyaum ua lwm yam los ntawm lwm tus.
