New Livery Yamaha YZR M1 2013

Yamaha Factory Racing has unveiled its new bikes and liveries in Jerez ahead of the final Official MotoGP™ Pre-Season Test. For the first time since 2010, Jorge Lorenzo is joined by fellow world champion Valentino Rossi.

Rossi’s return to Yamaha is one of the major talking points of 2013, as the nine-time title winner reunites with reigning champion Lorenzo for a fourth year together; the latter is aiming to become the first back-to-back champion since Rossi in 2008 and 2009. Friday’s unveiling took place in front of the gathered media before company representatives and the riders staged a press conference.

Kondisi Atmosferik dan Efisiensi Volumetrik

well kondisi mesin kendaraan tidak lepas dari namanya performa dan kemampuan dalam mengeluarkan kareakternya sendiri...ditentukan oleh yang namanya kondisi lingkungan... trus apa hubungannya? ya jelas ada donk... kalau kita mamakai kendaraan dilokasi tropis, itu akan sangat berbeda dengan kondisi pemakaian dibenua dengan 4 musim...  Contoh yang baik adalah bagaimana menjelaskan mengenai Kondisi Atmosferik dan efisiensi volumentrik pada kendaraan...

Characteristic Operation....!!! kinematika Torak/Piston...!!!

Internal Combustion Engine atau diIndonesia dikenal dengan Motor Bakar memang sangat dibutuhkan sekali, bukan hanya menjadi alat untuk membantu aktivitas manusia tetapi juga sudah menjadi gaya hidup... contohnya ya buat balapan lhaa.... GASSPWOOLLL!!!

Piston/Torak yang bergerak pada Internal Combustion Engine mengalami yang namanya Gerak Torak/Piston...

Gambar diatas menunjukkan Gerak Torak Primer, Dimana Gerak Torak Primer adalah Gerak vertikal yg ditentukan oleh tinggi-rendahnya posisi sejumlah titik dari lingkaran engkol.

 Gambar diatasini adalah diagram Gerak Torak Sekunder. Gerak Torak Sekunder sendiri adalah Gerak mendatar yang ditentukan dari penyimpangannya dari posisi horisontal.

Dalam sekali putaran poros engkol, batang penghubung berada dua kali pada kedudukan a dan d, dan empat kali pada kedudukan b dan c.

Racing Leather on MotoGp.....!!!

Race leathers provide the first line of defence for competitors in MotoGP when they suffer the occasional crashes and slides that all riders go through. With corner speeds quicker than ever and lean angles becoming increasingly acute the importance of a good set of leathers cannot be underestimated.

The most common way a rider comes off his MotoGP bike is to lose control of the front or rear tyre when leaning into a corner. This usually results in the rider sliding along the asphalt and onto the gravel at the side of the racetrack, sometimes apparently seamlessly, though almost always at high speeds. Clearly doing this with exposed flesh, normal clothing or inadequate leather protection would result in massive damage to the skin and other parts of the body.

PROTECTION

The various manufacturers supplying the leathers to the MotoGP participants therefore design the outfits to be as protective as possible – but they must also be aerodynamic, breathable, comfortable, durable, flexible, light and water resistant.

The MotoGP leather suits are mainly made of kangaroo leather, which is more resistant, more flexible and weighs less than cow hide. The leathers have to provide strong resistance and protection from abrasion and impact in particularly vulnerable areas such as the back, elbows and knees - whilst also giving the riders the elasticity they need when utilizing their lightening quick reflexes.

Of course the riders’ leathers also have to work perfectly in tandem with the helmets to stabilise the head, so the ‘humped’ back protectors the race outfits carry fit snugly against the helmets allowing air to glide over them aerodynamically when the riders are in the customary hunched riding position. When stood upright and off their racing machinery the back hump built into the back of the leathers can clearly be seen, but they are also fairly flexible to allow movement and bending of the back - in the right direction.

The built-in spinal column protection units and the chest protectors the leathers also carry mainly use carbon, kevlar and titanium combinations to safeguard the riders without weighing them down. Indeed the overall weight of a Grand Prix rider’s leathers will of course vary in relation to his physical stature, with the entire weight of the leathers usually totalling around 3kg to 3.5kg
