6. ## What is Ampere's law?

Now that is an interesting question! Do you mean Ampere's circuital law? or Do you mean Ampere's force law?
7. ## Introducing Engineering Subjects study clubs

Industrial safety,tool and die making
8. ## Compressor or Heat Exchanger?

If the process is to compress and then cool (or heat ) the medium, then design the compressor first. Having done so, you should be able to estimate its flow rate and pressure rise, and, most importantly, the temperature rise. With that, you know the capacity of heat exchanger required.

11. ## 'Flying car' tested by the Japan which hovers steadily for a minute

Hi, my educated guess would be in some long years... besides the tech challenge there's the legal one. BTW even for the prototype consider the weight of lights, wipers and stiff nets for people vs blade protection; (I wonder why there's no way to invert the gravitational polarity (in a controlled fashion), to stay off the ground) creating an antigravity field to bodies..... ; )

Excellent work sir but on safety make sure about the propellers speed and weight carrying capacity and add a air bag in the passenger cabin and add sensor for the automatic control.

Nice development to NEC the world is growing up so fast.
16. ## 'Flying car' tested by the Japan which hovers steadily for a minute

super it's Good project for world wide, improve the flying height above 15 to 20 meters and added to the Airbag system for passenger safety, Navigation system and add Highly equiped sensors.All the best for this flying car project team.
17. ## 'Flying car' tested by the Japan which hovers steadily for a minute

Flying car' hovers steadily in test flight by Japanese electronics company NEC Japanese electronics maker NEC Corp. on Monday showed a “flying car,” a large drone-like machine with four propellers that hovered steadily for about a minute.The test flight reaching 3 meters (10 feet) high was held in a gigantic cage, as a safety precaution, at an NEC facility in a Tokyo suburb. The Japanese Government is behind so-called flying cars, with the goal of having people using them by the 2030s. A flying car by Japanese startup Cartivator proved unsuccessful after it crashed during a demonstration in 2017, but company bosses say they have since developed their technology so their machines can last longer. NEC is one of more than 80 companies sponsoring Cartivator's flying car. The goal is to deliver a seamless transition from driving to flight like the world of “Back to the Future,” although huge hurdles remain such as battery life, the need for regulations and safety concerns. NEC officials said their flying car was designed for unmanned flights for deliveries but utilized the company’s technology in its other operations such as space travel and cybersecurity. Similar projects are popping up around the world, such as Uber Air. The global ridesharing giant's aerial taxi service pilot — which will run in Melbourne as well as the US cities of Dallas and Los Angeles — aims to connect transport hubs like airports to central city sites. The rideshare company said test flights were due to start from 2020 and plans were for commercial operations to begin from 2023. News credit :Japan times
18. ## Explain with reasons which theory of failure is best suited for : ...

For Brittle Materials, Max Principal stress theory is suitable as it considers Uni-axial tension or compression and fact that brittle material fails at tension For Ductile Materials, there are two theories applicable depending on loading condition/application Max. Shear stress theory is suitable for all conditions of loading as it considers yielding as design criteria and the fact that ductile material is weak or yield at shear first and fails at tension. Shear strain energy/Von-mises theory suits when there is no uni-axial loading ie, when we have multiaxial loading on the system, and it considers equivalent max normal/shear stress and fall little below satisfactorial design.
19. ## Important dates GATE 2020

Tuesday, 3rd September 2019 GATE Online Application Processing System (GOAPS) Website Opens Tuesday, 24th September 2019 Closing Date for Submission of (Online) Application (through Website) Tuesday,1st October 2019 Extended Closing Date for Submission of (Online) Application (through Website) Friday, 15th November 2019 Last Date for Requesting Change of Examination City (an additional fee will be applicable) Friday 3rd January 2020 Admit Card will be available in the Online Application Portal (for printing) GATE 2020 Examination Forenoon: 9:30 AM to 12:30 PM (Tentative) Afternoon: 2:30 PM to 5:30 PM (Tentative) Saturday, 1st February 2020 Sunday, 2nd February 2020 Saturday, 8th February 2020 Sunday, 9th February 2020 Monday,16th March 2020 Announcement of the Results in the Online Application Portal

Introduction Graduate Aptitude Test in Engineering (GATE) is an examination conducted jointly by the Indian Institute of Science (IISc), Bangalore and the seven Indian Institutes of Technology (at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) on behalf of the National Coordination Board (NCB)-GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India. Qualifying in GATE is a mandatory requirement for seeking admission and/or financial assistance to: (i) Master’s programs and direct Doctoral programs in Engineering/Technology/Architecture and (ii) Doctoral programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies. Even in some colleges and institutions, which admit students without MHRD scholarship/assistantship, the GATE qualification is mandatory. Further, many Public Sector Undertakings (PSUs) have been using the GATE score in their recruitment process. The information in this brochure GATE_2020_IB.pdfis mainly categorized into Pre-Examination (Eligibility, Application Submission, Examination Centres, etc.), Examination(Pattern, Marks/Score, etc.) and Post-Examination (Answers, Contests, Results, Scorecard, etc.) sections. About GATE 2020 Graduate Aptitude Test in Engineering (GATE) is basically an examination on the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/Technology/ Architecture and post-graduate level subjects in Science. GATE 2020 will be conducted for 25 subjects (also referred to as “papers”) and it would be distributed over 1st, 2nd, 8th & 9th of February 2020. The GATE examination centres are spread in different cities across India, as well as, in six cities outside India. The examination would be purely a Computer Based Test (CBT). The GATE score would reflect the relative performance level of the candidate in a particular subject, which is quantified based on the several years of examination data. Note that the GATE 2020 score is valid for THREE YEARS from the date of announcement of the results. GATE_2020_IB.pdf
