Automotive Developments 1600-The Dutch employed wind power to propel sail-mounted carriages which raced along at 20 mph and held scores of passengers. It is quite probable that both speed and load capacity were exaggerated. Later, small carriages were equipped with wind-mills, the mill vanes geared to the wheels. These were probably the first land vehicles to be propelled by

Mechanical Engineering as a Profession 1、 Introduction Scientists study the world as it is, engineers create the world that never has been What is engineering Engineering is the art of applying scientific and mathematical principles, experience, judgment, and common sense to create things that benefit people In other words, engineering is the process of producing a technical product or system to meet a specific need

Sections Threaded fasteners and power screws Rivets Springs Sliding Bearings Rolling-Element Bearings Spur Gears Helical Bevel and worm gears Threaded Fasteners and Power screws Classes of Fasteners They may be classified into two broad categories: Removable and Permanent Removable Fasteners are defined as those that can be easily removed with hand tools and without damaging any parts. Ordinary nuts and bolts are typical examples
