How Bridges Work" We are a species of bridge builders. Since time out of mind, humans have engineered structures to surmount obstacles, such as, say, Jiaozhou Bay. The body of water is now home to a 26.4-mile (42.5-kilometer) bridge that links the busy Chinese port city of Quingdao to the Chinese suburb of Huangdou. We've tamed steel, stone, lumber and even living vegetation, all in an effort to reach the places, people and things we desire. Although the concept itself is as simple as felling a tree across a creek, bridge design and construction entails serious ingenuity. As a result, we inhabit a planet of bridges, some as ancient as Greece's 3,000-year-old Arkadiko bridge or as unchanged as India's 500-year-old Meghalaya living bridges, which are coaxed into existence from growing tree roots (more on that later). In this article, we'll get to know the bridges we so often take for granted (we literally walk and drive all over them), as well as the designs that make them possible.

Designing Your Lego Creation" The first thing you'll need to do is determine exactly what kind of scale you'll be using for your project. This will set the stage for everything from how many bricks you need to how long your project is likely to take. You can make a pocket model, which is basically anything that's small enough to be carried in your pocket. At the other end of the spectrum is sculpture scale, which can be life-size or smaller, but is generally very large. In between is minifig scale, in which you plan the size of your design around the size of the minifigures that will use it. There's no wrong way to build with Lego bricks, so different people's construction methods can vary greatly. Some people prefer to plan their creations out step by step, or to use computer software to help in their design process.

Making Lego Bricks" All of the basic Lego elements start out as plastic granules composed primarily of acrylonitrile butadiene styrene (ABS). A highly automated injection molding process turns these granules into recognizable bricks. The making of a Lego brick requires very high temperatures and enormous pieces of equipment, so machines, rather than people, handle most of their creation. When the ABS granules arrive at Lego manufacturing facilities, they're vacuumed into several storage silos. The average Lego plant has about 14 silos, and each can hold 33 tons of ABS granules. The machines melt the granules at temperatures of up to 450 degrees F (232 degrees C), inject the melted ABS into molds and apply between 25 and 150 tons of pressure. When the bin fills, the molding machine signals a robot to pick it up and carry it to an assembly hall. From there, the elements go into packages, as we'll see in the next section.

พื้นเอียง (The Inclined Plane) จาก Youtube พร้อมคำแปลภาษาไทย เครื่องกล: พื้นเอียง (Inclined Plane) หน่วยการเรียนรู้นี้แบ่งออกเป็นห้าหัวข้อครับ หัวข้อที่คุณจะได้ดูต่อไปนี้จะเกี่ยวกับ “พื้นเอียง” (Inclined Plane) จากนั้นจะมีตอนที่เกี่ยวกับ “ไม้คาน” ต่อไปคือ “ข้อได้เปรียบเชิงกลและแรงเสียดสี” และตอนเกี่ยวกับ “ไขควงและวงล้อ” และตอนสุดท้ายเกี่ยวกับ “รอก” แต่เราจะเริ่มเรื่องกันด้วย “พื้นเอียงครับ” คุณไม่มีแรงพอที่จะยกถังใบนั้นใช่ไหมครับ ถ้าจะยกมันคุณต้องใช้แรงมากเท่าไหร่ล่ะ แล้วมันหนักเท่าไหร่ล่ะ เพราะฉะนั้นคุณต้องมีแรงอย่างน้อย 800 นิวตันถึงจะยกถังขึ้นไปไว้บนรถบรรทุกได้ แล้วต้องยกสูงเท่าไหร่ ประมาณหนึ่งเมตรใช่ไหม แล้วต้องใช้พลังงานกี่จูลล่ะ ลองคำนวณดูสิครับ นี่ไงล่ะ เครื่องกลของคุณ ครับผมรู้ มันเป็นแค่ไม้กระดาน แต่มันก็เป็นเครื่องกลด้วยนะ ลองเคลื่อนย้ายถังขึ้นไปไว้บนหลังรถดูสิครับ แล้วคุณก็รู้เอง เหมือนเวทย์มนต์เลยใช่ไหมล่ะ ไม่ใช่หรอก มันใช้หลักการเดียวกันกับตอนที่คุณแบ่งถังออกเป็นสี่ส่วนเลย เพราะฉะนั้น หากคุณเป็นคนเมาลิฟท์ ก็ใช้ “พื้นเอียง” แทนก็ได้นะครับ

Engineering Education for Kids Summer job available Princeton students: looking for a summer job? Like Legos? If you are interested or would like more information, contact Prof. Upcoming Events Student Organizations Fair: September 12th, 12:00-3:00 Princeton students Want to participate in any of these? Parents/teachers Want us to do an event at your school? Overview of PEEK PEEK is a program through which undergraduate students have the opportunity to visit elementary school classrooms and teach children basic principles of engineering using LEGO Mindstorms robotics kits. Curricula The following links are for curricula we have used at Riverside Elementary School (2004-5), developed by Roz Echols and Jen Lewellen, based largely on material from the CEEO at Tufts. Recent Events Contact Information If you are interested in being a member of PEEK and volunteering to visit classrooms or help out with engineering nights, please send email to Josh Israel and Jane Yang.
