SolidWork

what is solidworks ? SolidWorks is a popular 3D computer-aided design (CAD) software that is used for creating and designing complex models and assemblies in mechanical engineering, product design, and other industries. It is developed by Dassault Systèmes, a French software company that also owns other popular software such as CATIA and SIMULIA. SolidWorks provides a range of tools and features for creating 3D models, such as sketching, surface modeling, solid modeling, sheet metal design, and assembly modeling. It allows users to simulate and analyze the performance of their designs before manufacturing, including motion analysis, finite element analysis (FEA), and computational fluid dynamics (CFD). It also supports collaboration and sharing of designs with other users through various formats such as STEP, IGES, and STL. SolidWorks is known for its user-friendly interface and intuitive design, which makes it easy for beginners to learn and use. It is widely used in industries such a...

Youtube Oxford Economics Report

YouTube Oxford Economics Report : नमस्कार दोस्तो,  हाल ही मे oxford economics ने एक रिपोर्ट मे कहा है की Youtubers की कमाई 6800 करोड़ कि है। यह आकडां  2020 का हैं जब भारत सहित पुरे विश्व भर मे lockdown लगा था। Youtubers ने 6,83,900 full time नौकरियों के बराबर GDP को मजबूत किया है।  आमतौर पर Youtube का इस्तेमाल किसी भी प्रकार के video देखने मे होता है चाहे वह entertainment हो, educational हो, न्यूज़ videos हो।  YouTube प्लेटफॉर्म पर youtubers 8 तरीको से monetization कर सकते है जिसमे Adsense की तरफ से कमाई, ब्रांड प्रमोशन, affiliate marketing अहम है।  इस समय देश मे YouTube के 44.8 करोड़ यानी की 448 मिलियन users है। Facebook के पास 41 करोड़ और Instragram के पास 21 करोड़ users हैं। Oxford Economics के अनुसार 40,000 से ज्यादा YouTube Channel के पास 1 लाला से ज्यादा Subscribers हैं। इनकी संख्या 45℅ की दर से हर साल बढ़ रही हैं।  इसे भी पढ़े : 1.

डिजिटल एम्नेसिया क्या है?

डिजिटल एम्नेसिया क्या है? नमस्कार दोस्तों, आज हम बात करेंगे Digital Amnesia के बारे मे। Digital amnesia क्या हैं ? ये human के ऊपर कैसे effect करता हैं? इससे कैसे बचें ? Digital Amnesia क्या है ? Digital Amnesia दो शब्दो से मिलकर बना है, digital + Amnesia. जिसमे amnesia का मतलब है lack of memory. आज के pandemic के समय लोग घरों मे रहने को विवश है जिससे वे ज्यादा समय मोबाइल चलाने, tv देखने , work from home से काम करने के कारण लैपटॉप या desktop पर ज्यादा वक़्त देते है जिससे उनमे निद समय पर आने मे तकलीफ होती है। निद ठीक से पुरा न होने पर brain के functionality कर असर करता है जिससे memory loss होने लगती है। जिसे हम आमतौर Digital Amnesia कहते है। Digital Amnesia कैसे बचें ? Yoga, exercise, walking - यदि आप चाहते है की आप को digital Amnesia न हो तो आपको हेल्थ पर ध्यान देना चाहिए। समय निकालकर योग करिए , exercise करिए , तहलिए। Eating Healthy - दूसरा  काम ये कर सकते है की अच्छा खाना खाये। खाने मे उचित कार्बोहाइड्रेट, वसा , vitamin ले । Deep Sleeping - किसी भी बीमारी से बचने के लिए अच्छी निद ...

Aircraft Design Fundamental : Aircraft Design

A ircraft Design Fundamental.                                                                Aircraft Design is a branch of engineering design. Which is usually accomplished by drawing/ drafting design is a more advanced version of problem solving technique that many people use routinely. Design is exciting, challenging, satisfying and rewarding. In general a design process includes three major operations : Analysis, Synthesis and Evaluation .  Analysis is the process of predicting the performance or behavier of Design . Evaluation is process of performance calculation. Synthesis is the vehicle of design.  Aircraft Design • Engg Mathematical Calculation  •Decision Marketing / Logical Selection In general aircraft design requires the participation of six disciplines. 1. Flight Dynamics 2. Aerodynamics 3. Propulsion...
