Coast Guard Academy cadets present designs ranging from medical devices designed to prevent pressure ulcer complications to propulsion shaft anti-roll bars designed for use on a heavy icebreaker such as the Coast Guard Cutter Polar Star for the Mechanical Engineering department’s capstone projects, April 26, 2017.
These designs not only provide cadets with a solid set of skills, which can be utilized in the fleet, but also could make positive impacts on individuals outside of the Coast Guard.

The project is provides a robust and relatively inexpensive system that can be easily manufactured, assembled, and controlled by other researchers, aiming to expand the research field and its knowledge base.

A finely made lapel badge issued to commemorate the centenary of The Institution of Mechanical Engineers (1847 – 1947). I think this badge depicts either George or his son Robert Stephenson, but hope someone can confirm which one please? George held the position of President of The Institution of Mechanical Engineers from 1847 to 1849 and his son Robert succeeded him as President from 1849 to 1853.
The Institution of Mechanical Engineers was founded 1847 at Birmingham and moved to London in 1877 then to its current location in 1898. The Institution advocates for and promotes the development of all forms of mechanical engineering and the interchange of information and ideas between professional organisations, schools, universities and the public. The Institution also holds many mechanical engineering competitions with the awarding of annual prizes for different fields of study.

I have never been a fan of thrash metal the likes of which the actual band Mötorhead used to play. However, the other day while disassembling a Gear Motor to be used in the ABU 2009 Robocon competition, I couldn't help but think of that particular genre of music and how closely it's style resembles that of a crude device like this gear-rich contraption. Both are often greasy, without tune they would screech their hearts out and purr like a white-lioness when operated under 95% duty cycle.
Ok, I lied, the resemblance is only to my eyes...they don't necessarily have to fill your imagination as well.
See what the BUET team is up against this year. We are just helping hands though :)

Steam donkey, or "donkey engine" is the common nickname for a steam-powered 'hoist' widely used in past logging operations, though not limited to logging. They were also found in the mining, maritime, and nearly any other industry that needed a powered winch.
This article concentrates on the self-contained equipment used for logging.
Design and usage
Steam donkeys acquired their name from the animals they replaced. They were classified by their type (simplex, duplex, logging engine, 3-drum, 2-drum, etc.) and their different uses (high-lead yarder, ground-lead yarder, roader, snubber, incline hoist, etc.)
A steam donkey comprised at least one powered winch around which was wound hemp rope or (later) steel cable, and usually a boiler. They were usually equipped with skids, or sleds made from logs, to aid them during transit from one "setting" to the next. The larger steam donkeys often had a "donkey house" (a makeshift shelter for the crew) built either on the skids or as a separate structure. Usually a water tank, and sometimes a fuel oil tank was mounted on the back of the sled. In rare cases, steam donkeys were also mounted on wheels. Later steam donkeys were built with multiple horizontally-mounted drums/spools, on which were wound heavy steel cable instead of the original rope.
[edit] Method of operation
This describes the use of a steam donkey for logging operations. In the simplest setup, a "line horse" would carry the cable out to a log in the woods. The cable would be attached, and, on signal, the steam donkey's operator (engineer) would open the regulator, allowing the steam donkey to drag or "skid" the log towards it. The log was taken either to a mill or to a "landing" where the log would be transferred for onward shipment by rail, road or river (either loaded onto boats or floated directly in the water).
If a donkey was to be moved, one of its cables was attached to a tree, stump or other strong anchor, and the machine would drag itself forward.
History
John Dolbeer of Crescent City, California, invented the donkey engine in August of 1881. The patent (number: 256553) was issued April 18, 1882. On Dolbeer's first model, a 150-foot, 4½ inch manila rope was wrapped several times around a gypsy head (vertically mounted spool) and attached at the other end to a log.[1][2]
The invention of the internal-combustion engine led to the development of the diesel-powered tractor crawler, which eventually put an end to the steam donkey. Though some have been preserved in museums, very few are in operating order. A great number still sit abandoned in the forests, rusting in the spot where they dropped their fires not so long ago.
A non-operational steam donkey accompanied by a plaque explaining the history of the machine is on permanent display at Grizzly River Run, an attraction at Disney's California Adventure.
[edit] Other uses
Steam donkeys were also found to be useful for powering other machines such as pile drivers, slide-back loaders (also known as slide-jammers), and cherry-pickers (a sled-mounted crane used for loading logs, that a grading crew had cut down, onto railroad cars).
An auxiliary engine on a sailing craft (which does propel the vessel) is still sometimes informally known as "the donk".
