  The principle of  rocket propulsion  works on the ' Newton's Third Law of Motion '.  It states that for every action, there is an equal and opposite reaction'. As far as the rocket is concerned, the engine of the rocket releases hot burning fuel in the downward direction Rocket works on the principle of  conservation of momentum . Rocket ejaculates gases in backward direction which creates momentum of the gases backwards and thus by conservation of momentum, the rocket gets momentum in the forward direction making it move forward. when the rocket is released the pressure inside the body decreases as the speed increases and launches the rocket upwards There are four major systems in a full scale rocket;   Structural system.  Payload system.  Guidance system.  Propulsion system .

  The electric powertrain has a few salient components that differentiate it from its ICE counterparts. These are,   Battery pack Accumulator Precharge Circuit Precharge circuit   Insulation Monitoring Device Battery Management System        To understand how the different parts of an electric powertrain interact with each other, you should first understand the flow of energy in an Electric Vehicle. Energy from the electric grid is stored in the battery pack, from where it goes to the pre-charge circuit, and from there to the motor, where the electric energy is converted into kinetic energy.  The electric powertrain has a few salient components that differentiate it from its ICE counterparts.

The power of a MotoE bike comes from a permanent AC magnet motor that generates 158bhp and 215Nm of torque from standstill. Enel X MotoE has been the hub for research and developments in the field of electric motorcycling. A season in MotoE consists of seven races that runs on the same tracks as MotoGP. So, without much further ado, let us get deep into the electrifying waters of MotoE. Silent Weapons The 18 FIM Enel MotoE World Cup riders use the Energica Ego Corsa motorcycle to battle out the championship title. It is built by the Energica Motor Company which was officially founded in 2014 with the sole purpose of creating high-performance sustainable motorcycles. The power of a MotoE bike comes from a permanent AC magnet motor that generates 158bhp and 215Nm of torque from standstill. Top speed comes in at 270kmph which is at par with its sister class, Moto2 where the top speed is around 295kmph. The juice for power is stored in a 20 kWh High Voltage Lithium-Ion battery which has it

எரியன் மின்கலம்   (Fuel cell)  இரசாயன ஆற்றலை நேரடியாக மின்னாற்றலாக மாற்றக்கூடிய ஒரு சாதனம் ஆகும் [1] . எரிபொருள் மின்கலன், எரிபொருள் மின்கலம், எரிபொருள் கலன், எரிபொருள் கலம் என்ற பெயர்களாலும் இதை அழைக்கிறார்கள். மற்ற மின்கலங்களைப் போல இதிலும் நேர் மின்வாய் ஒன்றும் எதிர் மின்வாய் ஒன்றும் இவற்றுக்கிடையில் ஒரு மின்னாற்பகுபொருளும் இடம்பெற்றுள்ளன.  ஐதரசன்  மிகப்மிகப் பரவலாகப் பயன்படுத்தப்படும் ஓர் எரிபொருள் ஆகும். ஆனால், சில நேரங்களில் இயற்கை வளிமம் (natural gas) போன்ற ஐட்ரோ கார்பன்களும் மெத்தனால் போன்ற ஆல்ககால்களும் எரிபொருளாகப் பயன்படுத்தப்படுகின்றன. எரிபொருள் மின்கலன்கள் என்பவை சாதாரண மின்கலங்களிலிருந்து வேறுபட்டவை. எரிபொருள் மின்கலன்களுக்குத் தொடர்ச்சியாக ஆக்சிசனனும்/காற்றும் எரிபொருளும் இருக்க வேண்டும். இல்லையெனில் வேதிவினை நிகழாமல் போகக்கூடும். எனினும், இந்த மூலங்கள் இருக்கும் வரை தொடர்ந்து மின்னாற்றல் உற்பத்தியாகிக் கொண்டே இருக்கும். நேரடி மெத்தனால் எரிபொருள் மின்கலத்தின் செய்முறை விளக்கம். படத்தின் நடுவிலுள்ள கனசதுர வடிவ ஏடுகளே எரிபொருள் மின்கல அடுக்கு ஆகும்.

  PIEZOELECTRIC SENSOR Piezoelectricity is the charge created across certain materials when a mechanical stress is applied. Piezoelectric pressure sensors exploit this effect by measuring the voltage across a piezoelectric element generated by the applied pressure. They are very robust and are used in a wide range of industrial applications. One example of such a piezo sensor is an accelerometer. Accelerometer sensors often measure vibration or acceleration of various devices, such as motors, pumps, etc. They are used in stethoscopes, and ultrasound, to measure the effectiveness of anaesthesia, for various measurements during sleep studies and within pacemakers to detect the level of movement and activity of the patient. Some other more industrial applications which use Piezoelectric sensors are; Within accelerometers. The output power from the piezoelectric sensor was produced in AC source form that cannot be used directly for low load electronic device. Therefore, it needs to convert

  Alternating electric current flows through the  solenoid  on the left, producing a changing magnetic field. This field causes, by electromagnetic induction, an electric current to flow in the wire loop on the right. Electromagnetic  or  magnetic induction  is the production of an  electromotive force (emf)  across an  electrical conductor  in a changing  magnetic field . Michael Faraday  is generally credited with the discovery of induction in 1831, and  James Clerk Maxwell  mathematically described it as  Faraday's law of induction .  Lenz's law  describes the direction of the induced field. Faraday's law was later generalized to become the Maxwell–Faraday equation, one of the four  Maxwell equations  in his theory of  electromagnetism . Electromagnetic induction has found many applications, including electrical components such as  inductors  and  transformers , and devices such as  electric motors  and  generators .

  SELF - DRIVING CAR. Self-driving car, also known as an autonomous car, driver-less car, or robotic car (robo-car),is a car that is capable of traveling without human input.Self-driving cars use sensors to perceive their surroundings, such as optical and thermographic cameras, radar, lidar, ultrasound/sonar, GPS, odometry and inertial measurement units.[6] Control systems interpret sensory information to create a three-dimensional model of the surroundings. Based on the model, the car identifies appropriate navigation paths, and strategies for managing traffic controls (stop signs, etc.) and obstacles. Once the technology matures, autonomous vehicles are predicted to impact the automobile industry, health, welfare, urban planning, traffic, insurance, labor market and other fields. Autonomy in vehicles is often divided into six levels,according to a system developed by SAE International The SAE levels can be roughly understood as Level 0 – no automation; Level 1 – hands on/shared contr

 Nanorobotic Systems can have various potential uses in the healthcare system. Currently, the conceivable uses are for diagnosis, treatment, and surgery, and research is going on to get the desired result in the respective fields. With technological advancement, nanorobotics is expected to have several new medical applications and are expected to bring major transformations in cancer treatment, diabetes monitoring, wound-healing (regenerative medicine), dentistry, and blood monitoring (blood clot), among several others. Nanorobotics comprises various nanoscale size components, and each of the components can be built to carry out a specific function. The different components can perform tasks such as sensing, actuating, signaling, processing information, or exhibiting swarm behavior at the nanoscale level. For example, in the case of diagnostics and screening, the ultimate aim is to reach an area in the body where passive nanoparticles cannot go. The Nanorobotic can be used as a contras
