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.

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 :)

Braden Gandee, 12, receives an installation of an addition to his wheelchair that a University of Michigan ME450 team designed for him that will allow for him to play soccer with his brother and classmates at school.
Gandee was born with cerebral palsy and has been limited to a wheelchair, often running over the soccer ball instead of pushing it forward when he tried to play with his brothers and classmates. A team of U-M engineers in ME450, a capstone senior course for undergraduates, designed an addition that will allow Gandee to dribble and kick and a soccer ball.

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".

Professor James Holly Jr., addresses his MECHENG 499: Mechanical Engineering and Racial Justice in the Francois-Xavier Bagnoud Building on the North Campus of the University of Michigan in Ann Arbor on Wednesday morning, March 22, 2023.
This is the second time the course, developed by Holly in 2021, has been offered. He typically begins with a key question, such as: “Is technology a barrier to, a tool for, or a non-factor for racial justice?” In this course, Holly wanted his students to use critical thinking in their responses.Traditional curricula often emphasize making, doing, and calculating—the tangible sides of engineering. Yet there isn’t always time and space for students to examine how their thoughts are being deliberately created and facilitated. Discussion questions are designed to give students the opportunity to both think collaboratively with others, as well as to speak up. Holly calls it “Think-Pair-Share,” where students first think of their own answers, pair up to discuss them, and then share with the whole classroom.

A seating chart is studied during an experiment to understand how many infectious aerosol particles others in a classroom expect to inhale under various mitigation scenarios inside 1311 EECS on North Campus in Ann Arbor, MI on Monday, May 17, 2021.
There's a lot we don't know about how these particles behave indoors, but a core conundrum is that while aerosols do not stay within six feet of their source, they're also not uniformly distributed throughout a room.
Using a smoke machine and particle spectrometers, similar to work they've done for the U-M Dental School and Blue Bus, these experiments explore the impacts of different mitigation measures including occupancy limits, masks and increased ventilation.
