Engineering & Design | College of Science & Engineering

The Engineering & Design Department office is currently closed for the safety of students, staff, and faculty.  We are working remotely and are available to answer your questions.  Please call 360.650.3380 or send an email to engd@wwu.edu.  We are available!  Thank you for your patience and understanding. 

 

The Engineering & Design Department, in the College of Science and Engineering, offers access to four Bachelor of Science degrees: Electrical Engineering, Manufacturing Engineering, Plastics & Composites Engineering, and Industrial Design. These programs place an emphasis on practical laboratory experiences, in addition to theoretical course work. Each program’s curriculum is designed with input from strong industrial advisory committees to prepare students for professional positions in industry. It is important to know that admissions and advising information is specific to each major and students are encouraged to become familiar with the requirements. 

Alumni

Graduates of the programs have consistently been placed in positions appropriate to their field of study. Companies that employ graduates include Alpha, Boeing, CH2M-Hill, Cypress Semiconductor, Daktronics, Fleck, Fluke, Janicki Industries, Mentor Graphics, Microsoft, Nike, Physio-Control, PACCAR, Pro-CNC, Oculus, R & D Plastics, Rane Corporation, Rothenbuhler Engineering, SpaceX, TEAGUE, Tempress, Triquest, Universal Avionics, and Safran.

Current Students

Students have numerous opportunities to participate in projects and undergraduate research with faculty members. Additionally, students can choose to work on projects directly with industry partners as part of their course work. Some of the companies that have participated in research and other projects include Anvil Studios, Artefact, Avante, Conterra, Microsoft, Milwaukee Tool, PACCAR, Nike, Tethers Unlimited, Hexcel, R&D Plastics, and Safran.

Who Invented the Bicycle? | Live Science

You might think that an invention as simple as the bicycle would have an uncomplicated past. But as it turns out, this highly popular invention has a history fraught with controversy and misinformation. While stories about who invented the bicycle often contradict one another, there’s one thing that’s certain — the very first bicycles were nothing like the ones you see cruising down the street today. 

The first known iterations of a wheeled, human-powered vehicle were created long before the bicycle became a practical form of transportation. In 1418, an Italian engineer, Giovanni Fontana (or de la Fontana), constructed a human-powered device consisting of four wheels and a loop of rope connected by gears, according to the International Bicycle Fund (IBF).

In 1813, about 400 years after Fontana built his wheeled contraption, a German aristocrat and inventor named Karl von Drais began work on his own version of a Laufmaschine (running machine), a four-wheeled, human-powered vehicle. Then in 1817, Drais debuted a two-wheeled vehicle, known by many names throughout Europe, including Draisienne, dandy horse and hobby horse. 

Curious contraptions

Drais built his machine in response to a very serious problem — a dearth of real horses. In 1815, Mount Tambora, in Indonesia, erupted and the ash cloud dispersed around the world a lowered global temperatures. Crops failed and animals, including horses, died of starvation, according to Smithsonian magazine. 

Drais’ hobby horses were a far cry from the aerodynamic speed machines that are today’s bicycles. Weighing in at 50 lbs. (23 kilograms), this bicycle ancestor featured two wooden wheels attached to a wooden frame. Riders sat on an upholstered leather saddle nailed to the frame and steered the vehicle with a rudimentary set of wooden handlebars. There were no gears and no pedals, as riders simply pushed the device forward with their feet.

Drais took his invention to France and to England, where it became popular. A British coach maker named Denis Johnson marketed his own version, called “pedestrian curricles,” to London’s pleasure-seeking aristocrats. Hobby horses enjoyed several years of success before they were banned from sidewalks as a danger to pedestrians. The fad passed, and by the 1820s, the vehicles were rarely seen, according to the National Museum of American History (NMAH).

Bone shakers and penny-farthings

Bicycles made a comeback in the early 1860s with the introduction of a wooden contraption with two steel wheels, pedals and a fixed gear system. Known as a velocipede (fast foot) or a “bone shaker,” the brave users of this early contraption were in for a bumpy ride.

The question of who invented the velocipede, with its revolutionary pedals and gear system, is a bit murky. A German named Karl Kech claimed that he was the first to attach pedals to a hobby horse in 1862. But the first patent for such a device was granted not to Kech but to Pierre Lallement, a French carriage

Transportation Science

The logistics services have gone a means forward within the transport sector and in the present day you can not discover one single transport company who does not present logistics companies to its purchasers. The execution management and provider communication helps the shippers to seek out the tools needed to help them in selecting the best carriers along with shipping value calculation. Vancouver’s neighbours have transportation plans that talk to growing travel by foot, bicycle, and transit, though they differ in focus, method, and scale.

The stories present far we’ve come to meeting the mode share-goals of the Transportation 2040 Plan and Greenest City Action Plan. One of many earliest methods to move people and issues was by traveling within the water. If you’re coming into a business involving the motion of goods reminiscent of transport, trucking, courier services or logistics then additionally, you will have the chance to spread your model far and wide.

Beginning a pet transportation enterprise really relies on the size that you really want your business to be. If you want to start on a smaller scale, all you really need might be a pickup truck that has been modified to be secure and suitable for the transport of animals.

We provide innovative and integrated onboard computing and cellular communications systems that allow managers to get data-pushed enterprise intelligence at their fingertips. Air freight has turn out to be extra frequent for merchandise of high worth; whereas lower than one % of world transport by quantity is by airline, it quantities to forty percent of the value.

Cruising around Chicago is a breeze by way of its huge public transportation system and fleet of taxis. Vehicles also require personalized seatbelts for wheelchair certain passengers. Because of the excessive price of constructing and sustaining roads, transportation was managed in accordance with tight stipulations and great care was taken that a relative mild most weight was allowed for the different modes of transport.

3) Price- I checklist this third on the record because, imagine it or not, value isn’t as huge as people need to play it out to be. You see, if your product does not make it is vacation spot safely and in good transit time, it will not matter for those who acquired a dust low-cost rate as a result of you’ll have a really unhappy customer.…
