THE 5 BEST BICYCLES IN THE WORLD: EXCELLENCE, PERFORMANCE AND STYLE

 

Are you fond of cycling like me? This post is perfect for you, then! Bicycles are one of the most popular means of transport in the world, valued for their versatility, sustainability and health benefits. Over the years, many brands have developed cutting-edge bicycle models, offering exceptional performance, innovative designs and high-quality materials. In this article, we will explore the five best bicycles in the world, considering criteria such as engineering, brand reputation, customer reviews and technological innovation.

THE ENGINE: THE HEART OF A CAR

In everyday life we ​​are used to seeing cars, buses and other means of transport. Do you know how they manage to work? How can take us everywhere wherever we go? Through a fundamental part of their structure: the engine.

THE 7 ENGINEERING WONDERS OF THE MODERN WORLD

 

You surely have already heard about the seven wonders of the world, but have you ever heard about the seven engineering wonders of the world? In fact, nowadays it isn’t enough to say seven wonders of the world because there are several types of “seven wonders of the world”: there are ancient wonders, natural wonders and engineering wonders.

 

In this article I would like to focus on the seven engineering wonders of the world, but first here are  the ancient ones, as categorized by Philo of Byzantium in 250 B.C.:  the Great Pyramid of Giza, the Colossus of Rhode, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Statue of Zeus, the Temple of Artemis, the Hanging Gardens of Babylon. The only ancient wonder still standing is the Great Pyramid of Giza.  

 

2-STROKE VS 4-STROKE ENGINES

You may have noticed I’m fond of cars and engines. That’s also why I’d like to be an engineer one day. Today I’m going to describe the most common types of car engines. You may have heard the terms 2 stroke and 4 stroke engines before, but do you really know all of the differences in their operation? I hope my post and the video below may help if you don't. 

The combustion engines are the most common type of engine with regard to means of transport like motorcycles, cars, busses and trucks but they are used also for small power tools like lawn mowers and chainsaws. In one of my articles in the blog I mentioned how they work but these two types have a small difference that change how they are made and used. How it works? A piston connected to the crankshaft by means of a connecting rod, flows up and down in a cylinder thanks to the force generated by the explosions of a mixture of air and gasoline. The connecting rod has the task of transforming the piston motion into a rotary motion.  But let’s talk about the differences about 2-stroke and 4-stroke engines.

THE 10 FASTEST CARS IN THE WORLD

Once there were few cars capable of exceeding 400 km/h, but this is no longer the case. So let’s see which are the 10 fastest cars in the world. They all axceed abundantly 300 km/h and, at the same time, accelerating from 0 to 100 km/h in about three seconds. What is it to build such powerful cars and to enter the 10 fastest in the world? It  is first of all power and then the aerodynamics, both to penetrate the air and to prevent the car from tacking off. It may seem paradoxical, but the speeds involved are higher than many small planes. Returning to my ranking, I lined up the cars (from the least to the fastest) checking that they are currently in production and that they are approved for road use.

ENGINES FOR THE FUTURE

One of the most important problems in the world is air pollution. Industrial  production, transports and many human activities essential to welfare and survival pollute our planet. So we need to find new ways to produce things and to travel.

In this article I’m focusing on the automotive industry and what it’s been invented to reduce emissions.
