The basic car maintenance routine that one should do regularly is to clean it. Cleaning your vehicle should be a daily chore so that you can keep up with the dirt and grime that quickly accumulates. You may also hire someone to clean it, or visit a car garage for thorough cleaning. Knowing some car washing tips will make the chore even easier.more “Top 3 easy car washing tips and tricks”
Specific book, specified genres and bifurcated segments, not just the novels but special study books have been made available on online portals to benefit the preferred online shoppers. From all the gradual definitions, there are books for every profession & the exam related to it. Out of these specialized books, Aerospace engineering books can also be countered easily through online offers & discounts.
Here is a glimpse of the wide variety of books available for Aerospace engineers-
Indian Space Research Organisation (ISRO) – Polar Satellite Launch Vehicle (PSLV) conducted its thirtieth flight from the Satish Dhawan Centre, Sriharikota on July 10 with the heaviest payload ever for a commercial launch.
India has established itself as an efficient commercial launch pad for foreign satellites. This is the heaviest payload for a commercial launch. A successful PSLV-C28 launch would give a big boost to Isro’s commercial launch capabilities.
said Isro spokesman Deviprasad Karnik.
PSLV-C28 launched the UK’s 3 identical optical earth observation satellites- DMC3, built by Surrey Satellite Technology Limited (SSTL), & two technology demonstrator auxiliary satellites into space – the CBNT-1 and De-OrbitSail.
total 5 !
ISRO used the high end XL version of PSLV for the 9th time.The three DMC3 satellites each weighed 447kg & were launched into a 647km sun-synchronous orbit, the CBNT-1 – 9kg micro satellite, & De-OrbitSail, – 7kg nano satellite i.e
a total of 1357 kg !
Isro said on its website that accommodating the three DMC3 satellites each with a height of about 3 metre within the existing payload fairing of PSLV was a challenge.
After the hugely successful Mars Orbiter Mission, which completed 300 days in the Martian orbit a few days back, India is now planning a mission to Venus.
A combination of two words, Cube – an English word & li- an Swiss German diminutive word meaning ”small”. Researchers from the ETH Zurich’s Institute for Dynamic Systems and Control have developed the Cubli, a 15x15x15 cm device that can walk, jump, and balance itself on its edge or even on a corner.
Researchers said that balancing was not a big issue for The Cubli, while the problem was jumping up from the rest position because at that instant, it needed more energy so they used reaction wheels mounted on three faces of the cube which rotated at high angular velocities & then brake suddenly which caused cubli to jump.
Once the cube stood up on a corner, controlled motor torques were applied to balance on one point.
In addition to balancing, motor torques were also used for a controlled fall in any direction.
Combining these things – jumping up, balancing, and controlled falling — the Cubli is able to walk on its own !
