The device of best torque wrench involves the connection of two tools into one: a conventional adjustable wrench and a dynamometer. The first is needed to tighten the nuts, bolts and other threaded fasteners. The second measures the force of the applied force when tightening. Externally, the device resembles a metal tube with a scale on which the force applied to the torque is marked. This tool is indispensable for service stations and bicycle workshops, and many lovers of two and four-wheeled vehicles will come in handy.
Why use a torque wrench?
For years, the world knew only steel. Bicycle frames, car bodies, and even prams were made from it. Fortunately, a great variety of metal alloys has emerged today, from aluminum to carbon, which are used in mechanical engineering. They are made by them, as separate fastenings, elements, and the whole knots and units. And at each joint in the modern technology, the manufacturer indicates the required torque. Such is the one in which the mount exerts optimal pressure on the entire system. It is a torque wrench , the instruction for which is extremely simple, indicates this moment. If it is even simpler, then with the help of this device you can determine when it is necessary to tighten another couple of turns, and in which case it is more correct not to do this.
Some may have questions - why bother with this key at all, if for many years the master at the workshop did without it. The answer will not take long - changed times, materials, tools and requirements for the level of service equipment. The range of force pulling on the details began to write for good reason. This information when using a torque wrench will avoid:
bursting or stuck nuts;
And many more unpleasant situations, both for motorists and cyclists, and even in everyday life when installing equipment or furniture. By the way, it is especially important when the manufacturer recommends tightening all fasteners with the same force. And if the wheel bolts of the cars can still bear the tightness “by eye”, then the carbon fiber burst due to too much tightening of the bike seat. So it is better to purchase a torque wrench, especially for workers who regularly face repair of cars, motorcycles or bicycles.
WHAT ARE THE RACES? GUIDE TO THE FIVE MAIN TYPES OF MOTOR SPORT
1. Ring races
Track: closed racing track of complex configuration with a large number of turns.
The rules . On paper, the conditions are simple: you have to drive a few laps faster than your rivals and successfully complete the turns. But in fact, all these studs, apexes, Eski and chicane bring a lot of adrenaline to pilots and spectators. Ring races are the ones everyone dreams of: speed, race cars with a bunch of buttons, overalls that the burning fuel does not take, engines roar, tires squeal ... In general, it’s quite a man’s music.
Formula 1 - legendary ring racing design-class race cars with open wheels, which originate from the British races. This is the world championship in which everything is the same : the fastest cars, the biggest budgets, the most successful pilots and the coolest engineering teams that compete for their Cup of designers. The stages are called Grand Prix , for access to each of them you need to comply with many conditions, and the participation itself is the dream of any rider. This year, the fight also promises to be hot, although Formula 1 has lost its hot grid girls. Above the stars of these races in motor sport there is no one: Michael Schumacher, Sebastian Vettel, Lewis Hamilton, Rubens Barrichello, Alain Prost, Ayrton Senna, Mika Hakkinen ... The names speak for themselves.
The rules . Any rally is both an exam and a lottery. There are trails along ordinary roads, special stages and even superspecial sections on the track - they are more difficult, and this is where the serious struggle for skill and time takes place. There are no seasonal barriers, so it is not always clear in advance what coverage pilots will encounter on the way from point to point B. In the rally, of course, there is a detailed description of the route - a transcript that the navigator sounds. But the fact that you will be kindly informed about the springboard or the pit in front, somehow it does not become easier . The main competition in this category is the WRC (World Rally Championship) - the World Rally Championship under the auspices of the FIA, which is held at any time of the year.
