From cars and trucks to planes and trains, brakes work in a similar way on most different vehicles. There are even brakes in wind turbines! Here's a quick comparison of some common brake systems. Bicycle If you ride a bicycle, you know all about brakes. If you want to stop suddenly, you squeeze the brake levers on the handlebars. Thin metal cables running to the back and front wheels pull on small calipers, forcing thick rubber blocks to press against the wheels. As they do so, friction between the blocks and the metal wheel rims generates heat, reducing your kinetic energy, and bringing you safely to a stop. Although most bicycles still use caliper brakes, some use disc or drum brakes instead (described below). Motorcycle Motorcycles typically have disc brakes comprising a rotor and a brake pad. The rotor is a disc with holes (or slots) in it mounted on the side of the wheel. A brake pad, operated by a hydraulic cable, jams against the rotor to slow it down by friction. The holes

We all know that pushing down on the brake pedal slows a car to a stop. But how does this happen? How does your car transmit the force from your leg to its wheels? How does it multiply the force so that it is enough to stop something as big as a car? The layout of a typical brake system When you depress your brake pedal, your car transmits the force from your foot to its brakes through a fluid. Since the actual brakes require a much greater force than you could apply with your leg, your car must also multiply the force of your foot. It does this in two ways: ·           Mechanical advantage  (leverage) ·           Hydraulic force multiplication The brakes transmit the force to the tires using  friction , and the tires transmit that force to the road using friction as well. Before we begin our discussion on the components of the brake system, we'll cover these three principles: ·           Leverage ·           Hydraulics ·           Friction Leverage and Hydraulics The pedal is desi

If you have some detailed sketches for a robot prototype, customized eyewear, or designer toy, 3D printing lets you turn these ideas into tangible creations. Opening your own 3D printing operation could be the way to fuse your technical and artistic skills and turn them into a profit. Here’s what you’ll need to get your 3D printing business off the ground. 1.Software There’s a lot of great free open-source software out there. You might be able to rely on online shareware to complete your first few projects. However, as your business grows you’ll want to invest in at least a year-one license for 3D modeling software with 3D printing features. According to Micallef, some of the 3D-specific workflows of modeling tools that you should look for in software include checking printer models for 3D output, the ability to properly orient models on the print bed, and support generation, which ensures the model remains stable during the printing process. 2. Thermoplastic filament Materials are an

1.The first Lamborghini didn't even have an engine when they unveiled it. The 350 GTV may have been the world's first Lambo, and ultimately, it led to the creation of the supercar genre, but when it was first unveiled at the Turin Auto Show it wasn't even finished, so they put a bunch of bricks where the engine should have been and kept the hood shut the entire time. 2.The Four Rings in the AUDI Logo represent the FOUR companies of  AUTO UNION By 1932, the name fiasco between Horch the man, and Horch the company was water under the bridge. Horch (the company) and Audi entered an agreement along with two other German car manufacturers, DKW and Wanderer, to form Auto Union. The four rings, which Audi still uses today, originally represented the four companies of Auto Union. 3.Ferrari Engines are Musically Engineered Ferrari engines are musically engineered to sound perfect by utilizing 3rd and 6th harmonics on the air intake, like an organ or flute. 4.Most new cars fake engin

In 1920, the Maharaja was strolling along the streets of London when he chanced upon a Rolls Royce showroom. He decided to go in and inquire about the price and specifications of one of its luxury vehicles. The British salesman, who had no idea who the visitor was, took one look at the royal’s appearance and treated him just like any other poor Indian citizen. The Maharaja was shown out of the showroom by the discriminating salesman. After this insult, King Jai Singh came back to his Hotel room and asked his servants to call the showroom that King of Alwar city is interested in purchasing their few Cars. After few hours King reached the Rolls Royce showroom again but with his full astonishing royal manner and in his royal costume. Until he reached the showroom there was already red carpet on the floor and all the salesmen were bent with respect. The King purchased all the six cars that they had at showroom at that time and paid full amount with delivery costs. After reaching India, Kin

  What is CAD Software? The software you should use when designing something to be 3D printed is entirely dependent on what you are trying to make. In general, 3D design software falls into two categories. The first is CAD software and the second is 3D modelling software. Even though this is general, CAD software is usually used when creating industrial objects such as mechanical objects. On the other hand, 3D modelling software allows more artistic freedom as designs do not need to work mechanically, be functional or fit to a real-world device. Historically, 3D modelling software has been used in film animations and video games to make organic designs. However, it can also be used to create 3D printable models. Here we focus on CAD (Computer Aided Design) software. The software can be highly specific, it is designed to be a technical tool with functions in industrial design, mechanical design, architecture, and areas such as aerospace engineering and astronautics. A CAD model will con
