We don't think much about nails and screws, until we need to fix or build something. The screw is a fundamental tool in nearly all construction projects. While it may be small, it is a powerful invention that has changed the world forever. This accessible book introduces readers to this simple machine and its many uses through real-world examples. Detailed pictures with thorough annotations help readers understand key engineering concepts. Fascinating "Technology in Action" spreads give readers an inside look at how screws work. A fun spin on essential engineering information, this accessible book will have a place in any science curriculum.
With this book, kids will learn how screws work, where they're found, and their uses throughout history. They will learn that screws are simple machines that convert rotational motion into linear motion. A simple wood screw is made up of a metal shaft with a thread spiraled around it and a head with a groove in which a screwdriver can fit. When rotational motion is applied to the head of the screw, the screw converts the force to linear motion, which in turn drives the screw into the wood. Wood screws are just one example of this versatile simple machine, which will fascinate your budding scientific thinkers.
Loose Screws is a collection of sixty-nine amusing, often touching, anecdotes from the life of a Bronx boy who has lived and traveled throughout the world. The author, Gerry Tortorelli, is a retired business executive, who immigrated to Switzerland in his thirties with his young family. With stints in England and Canada and frequent visits to the family roots in Italy, his stories explore many cultures. Whether it be the story of how his sister celebrates Christmas in The Twelve Weeks of Advent, or how German words can be misinterpreted in English in A Good Fahrt.and a Douche, the anecdotes have a personal touch with which the reader can connect. A 22-year-old grudge is settled in the story Toothpaste, Mayonnaise, and Big Ben while fundraising for a new church in Canada is detailed in A Pregnant Nun and a Chicken at Mass. Not far away from any story, is Gerrys wife (the Queen), his daughters (the Princesses), and his serf sons-in-law. Loose Screws is a unique view of a life through the eyes of the one who lived it, a kid from the Bronx.
Screws are everywhere! They help keep buildings together and help us move and lift things. Come inside this book for a fun and fascinating look at this simple machine. Kids will love the fun with screws section.
Did you put the cap on the toothpaste tube today? Then you've used a screw! These simple machines are all around. Take a look inside and discover 13 different ways we use screws.
The screw is a simple machine that changed the world in remarkable ways. In the 1440s, the screw was central to the success of the printing press, which allowed scientists and great thinkers around the world to share ideas. Today, screws are necessary to hold a variety of objects together, from chairs to light bulbs. They also manifest in the forms of ceiling fans and airplane propellers. With approachable text and an image gallery of recognizable objects that use this simple machine, this book allows early readers to understand the forces and STEM concepts that make screws vital to the modern world.
Water screw conveyors have been in use for centuries. Their invention is attributed to Archimedes. However, the idea of using this Archimedean screw also as a hydropower screw to convert hydraulic energy into electrical energy did not emerge until the 1990s. More recently, hydropower screws have been used very frequently at hydropower sites and have now also attracted increasing interest from scientists and users worldwide. This is due to the machine's very good efficiency, it's simple and inexpensive design, and its fish compatibility. This book provides calculation fundamentals for hydropower screws. The author focuses on the description of the hydraulic processes and gives a design flow that can be used to design hydropower screws. The hydraulic behavior, dimensions, speed, efficiency, forces acting on the screw such as sag or lift, as well as the arrangement of the gearbox and the choice of generator are discussed. The theoretical equations, some of which are newly derived, are applied using examples. Finally, a design flow is given that can be used to easily adapt an optimally designed hydropower screw to a location. New findings presented in various scientific publications have been incorporated into the translation of the second German edition. In addition, experiments were carried out at different locations, which led to a better understanding of the available data basis. This has allowed the theoretical predictions of this book to be confirmed experimentally. In addition, the author has investigated a number of faulty installations and has been involved in the design of successful working waterpower plants equipped with hydropower screws.
This is the true story of one man's dream. The Cornalari Wizard is written from the diary and photo albums of Donald McKee. Ever had a dream? Donald did and he decided to build it. The 'Cornalari' is a sailing catamaran that was hand built by Donald in Stornoway, with a little help from his friends, and finally launched in 2000.
