تفنگ ریلی

تفنگ ریلی

تفنگ ریلی وسیله ای است كه با عبور جریان از جسمی (از طریق ریلی) می تواند باعث حركت شتاب دار آن شود. وقتی منبع ولتاژ قوی استفاده شود، تفنگ ریلی می تواند به عنوان سلاحی قوی عمل كند. مبانی این وسیله را می توان با ایمنی بیشتر به كمك باتری ٩ولتی نشان داد.

وقتی مقدار ولتاژ دستگاه كم باشد، می توان ریل را چندین بار استفاده نمود. اگر مقدار ولتاژ زیادباشد، تفنگ ریلی یك بار مصرف خواهد شد! زیرا ریل در فرآیند پرتاب (جرقه زدن و خراش افتادن ریل) خراب می شود.

چندین نوع تفنگ ریلی وجود دارد، و هر كدام به روش متمایزی جسم را شتاب می دهد. به روشی كه در اینجا استفاده شده است "موتور هم قطبی" می گویند.

تفنگ ریلی

توصیه می شود برای این فعالیت پژوهشی اولیاء محترم نیز كمك كنند.

 

وسایل مورد نیاز

تفنگ ریلی

١- یك تكه مقوا یا چوب به عنوان پایه (كه می تواند هر طولی داشته باشد). در دستگاه ما ابعاد آن ١٥*٤٥سانتیمتر در نظر گرفته شده است.

٢- دو نوار آلومینیومی، به پهنای ٥سانتیمتر (طول آن ٥ سانتیمتر بلندتر از پایه باشد)

٣- یك میله فولادی (یا آهنی) به طول ٥ سانتیمتر، شبیه میله جارختی

٤- دو آهن ربا كه در توسط رسانای خوب پوشش داده شده باشد. دقت كنید بدنه برخی آهن رباها رسانا نبوده و برای این پروژه مناسب نیستند.

٥- مقداری چسب سفید

٦- باتری ٩ولت

٧- دو گیره سوسماری

 

ابتدا پایه را چسب كاری (لایه نازك چسب) كنید. قرار است بر روی آن ورق آلومینیوم قرار دهیم.

تفنگ ریلی

سپس نوارهای آلومینیومی را به فاصله ١.٥سانتیمتر از یكدیگر بر روی پایه قرار دهید، و با انگشتان به نرمی روی آنها دست بكشید تا چروك ها از بین برود. حدود ٥ سانتیمتر از نوار آلومینیومی از یك طرف پایه آویزان باشد، بعداً ما باتری را به كمك گیره سوسماری به این ورق ها وصل می كنیم.

تفنگ ریلی

سپس باتری را با گیره سوسماری به آن وصل می كنیم. ما نگران قطب های باتری نیستیم. اگر تفنگ در جهت اشتباه پرتاب شلیك كرد، اتصال باتری را عوض كنید.

تفنگ ریلی

مرحله بعدی این است كه انتهای میله را با سوهان صاف كنید. این اجازه می دهد كه آهن ربا صاف و عمود به انتهای محور سیم (میله) وصل گردد. اگر انتهای سیم كاملاً عمود باشد آنگاه آهن ربا در حین حركت لنگ نمی زند.

تفنگ ریلی

حال آهن ربا را در انتهای سیم (محور آهنی) قرار دهید. قطب های دو آهن ربا باید در حین نصب طوری باشند كه یكدیگر را دفع كنند. علی رغم این موضوع، هر دو آهن ربا به میله آهنی وسطی محكم جذب می شوند. اگر آهن ربا ها قوی باشند هیچ چسبی برای این كار لازم نیست.

 

شلیك تفنگ ریلی

برای شلیك تفنگ ریلی، چرخ را روی ریل قرار دهید. مشاهده می كنید بلافاصله با شتاب حركت می كند. اگر چرخ حركت نكرد، احتمالاً آهن رباها در یك جهت وصل نشده اند. چرخ را بلند نموده، و یك آهن ربا را وارونه كنید، و دوباره امتحان كنید. اگر باز هم كار نكرد، باتری ها و اتصالات مربوط به آن را بررسی كنید. اگر چرخ ها در جهت اشتباه حركت كردند، حركت را از طرف دیگر آغاز كنید، یا جهت باتری را معكوس نمایید.
