السلام عليكم اليوم
بالمخطط والاشكال التقنيه اللي عم نقدمها
رقم 13
بدنا نبدا نحكي عن مخططات واللي باسمها hp
هاي hp اللي هو مايكل hp ب 2005 نشر
مخططات جدا جدا هامه
بتمثل خواصي تبعيت بشكل عام
خلينا بس لحن الغرض ونحن مثل ما حكينا انه
هي عباره عن صفحه واحده
يكون عندك كمكتبه ضمن الخواص
والبروبارتيزين لازم
طبعا مثل مانك شايفين هون لحنا عنا هلا
العلاقه هاي بين
يعني مقابل
خليني ابدا بالدين سيتي الدنسيتي يعني
بواحده
جرام يعني الف
او خلينا نقول تماما الف كيلو جرام صارت
اذا ميجا غرام هي الف كيلو جرام بالمتر
مكعب معناتها ان الرقم واحد هون بمثل لي
الماء الماء الف كيلو للمتر المكعب هذا
بالنسبه للماء وهوني انا عندي معناتها
اللي هون معناتها اثقل وهكذا اثقل منها
وانت فينك تراقب المواد اللي راح نيجي
عليها هون عندي المحور
بواحده ميجا باسكال ميجا مليون باسكال
باسكال يعني نيوتن مربع اذا بدي احولها
مشان اقدر افهمها نيوتن على سنتيمتر مربع
اوكي معناتها الميجا باسكال عم يمثل لي
100 نيوتن على سنتيمتر مربع ما هيك لانه
لحول من متر مربع لسنتيمتر مربع في عشره
الاف حولنا اذا فعليا انا ميتي نيوتن على
سم مربع الواحد ميجا باسكال اللي عندي هو
ميت نيوتن لا اذا افترضنا هيك بشكل تقريب
النيوتن هو مئه جرام مشان نفهمها هيك
بحياه العمليه ان كانه انا عم بحط معناتها
ميت غرام يعني عم نحكي على عشره كيلو جرام
بالسنتيمتر مربع اذا كل سنتيمتر مربع عم
اطبق عليه ضغط او في حال كان او سترينج
يعني
بطبق عليه يعني
استطاله خليني نسميها مثل ما حكينا 100
كيلوغرام على سنتيمتر مربع اوكي عشره عفوا
كيلو جرام على سنتيمتر مربع مشان تكون
دقيقين سامحوني اذا صار خربطه بالارقام بس
انت الغرض منه انت اكيد فهمان علي طيب هاي
عنا الواحد باسكال بنقدر نفهم اكثر مع
نضرب بعشره لما بدنا نطلع
العشره ميجا باسكال او 100 ميجا باسكال او
اواع الف ميجا باس كان وصلنا للجيك باسكان
اذا معناتها انا الماتيريال اللي عندي
اياها ضمن عائلات الميتلز الميتلز هي الام
تان هي السترينكس الاقوى ولا تنسى انا
ارفق لك هاي المخططات فقط لتفهم نحن عنا
المخطط الرئيسي في عالم الماتي هو
مع الستريم وكيف اي ماده انا لما بدي
اعملها شد او ضغط معناته بده يظهر معي
هالمخطط هذا وين محلها هاي هي محلها ولا
دائما خليني اقول وقت بدي اصمم دائما اني
بصمم على
التصميم هذا تبع
مكان التصميم اذا عائله الميتال عائله
السيراميك ولاحظ السيراميك عم تفوق ببعض
الاماكن مكانه وهي اخف لا ننسى السهم هذا
معناته انا هذا التارجت لالي بالتصميم
بالبحث عن مواد وانه بدي اطور المواد لشو
اللي بدي اسعى السعوده السعيده دائما نحو
الخفه مثل ما انك شايف
ونحو
اذا انا هذا الاتجاه اللي عندي اياه هذا
اتجاه التصميم اللي انا عندي اياه اذا
سيراميكس كومبوزه
هاي العائله تبعيتهم ناتشورال فعلا نحن
لما عم نحكي على
يعني دخلنا بمواد هي اخف من المي كوزن
وحتى الفومز اخ
معناته الرقم عما يزداد يعني هون 18 متل
ما انك شايف لانه هاي عشرين هاي يونت 18
فننتبه على امور الدينسيتي معناتها الوزن
اللي انا عندي اياه الكبر يعني قريب
للعشره او بمجال العشره اوكي او السيلفر
حوالي بعضهم واحد اقل سيلفر من الفضه
عفوا السيلفر النحاس وهكذا خلينا نراقب
الكربون
نانستركشر
دخلنا بخفه الوزن الغائب كنا بالعشره صرنا
عم نحكي على اثنين اوت
للجرافين مثلا او للكربون
ضرائب الوندي
اهميته اطاعنا الوان
دخلنا بالعشره جيجا باسكال او لل 100 جيجا
باسكال اذا فعلا احنا لما بدنا نناقش
اليوتيوب لاحظ هالقيمه هاي 100
حولها الى نيوتن على او كيلو جرام على
سنتيمتر مربع وشوف القيمه اللي عندك وراقب
لي موضوع الدينسيتي لالها واعمال مقارنه
اللي ذكرت لك اياها بعالم الكوبوز اذا
معناتها انا هاي المواد النانو متريه
ضمنها العائله ثلاثه الواندي ميتالي او
نانو
هاي اضافه لغرض زياده المتانه وتخفيض
الوزن طبعا المواد شايفين القيمه تبعيتها
ولكن انا بضيفها سواء للسيراميكس او بدي
اضيفها للبولمرز او بدي ضيفها ضمن خرائط
المعدنيه مع شو الامبروفمنت بدي احصل
عليها هذا موضوع تاني ناقشناه بالكومبوزي
الغرض من الفيديو تكون عنا هالصفحتين هدول
على
موبايلك بالوقت اللي انت بدك تاخذ اي قيمه
ترجع لهالصوره هاي وتستفيد منك قيم حقيقيه
القيم هون حقيقيه بدانا هلا بالعلاقه بين
سترينكس مع الدنستي في عنا كتير
خواص ميكانيكيه مع بعضها البعض رح نناقشه
بالتكنيكال تشارت اللي عم نقدمك الاسبوع
ان شاء الله بتمنى الفيديو يكون مفيد
والسلام
