Iron Ring Clock

The McMaster Faculty of Engineering is a faculty located at McMaster University in Hamilton, Ontario. The faculty was established in 1958 and was the first engineering program to developed problem-based learning curriculum. It currently has seven departments in chemical engineering, civil engineering, computing and software, electrical and computer engineering, engineering physics, material science and engineering and mechanical engineering. The faculty offers bachelors, masters, and doctoral degrees.

The faculty is home to 1 Canada Excellence Research Chair, 13 Canada Research Chairs, 4 Natural Sciences and Engineering Research Council chairs, and 14 Endowed Chairs.

Programs

The B.Eng. undergraduate programs are accredited through the Canadian Engineering Accreditation Board. All undergraduate students take a common first-year program, which outlines the fundamentals of engineering disciplines. At the end of the first year, students choose one of fourteen program disciplines. This includes some five-year programs such as Engineering & Management, Engineering & Society, or streams in Integrated Biomedical Engineering and Health Sciences.

Graduate programs in biomedical engineering are offered through the School of Biomedical Engineering, and graduate engineering practice programs through the Walter G. Booth School of Engineering Practice.

The joint McMaster-Mohawk Bachelor of Technology program offers four-year bachelor-degree programs in engineering technology, including process automation technology, biotechnology and automotive and vehicle technology, as well as degree-completion programs in civil engineering infrastructure technology, computing and information technology, energy engineering technology and manufacturing engineering technology.

History

In 1956, McMaster named its first Director of Engineering Studies – Dr. John W. Hodgins, a Chemical Engineering professor from the Royal Military College – to develop a full engineering program for the university. The program was approved by the McMaster University Senate in February 1958. The engineering building, now John Hodgins Engineering Building, officially opened a few months later. The first class of 25 students graduated in 1961.

Five departments were established in the first two years – Chemical, Civil, Electrical, Mechanical and Metallurgical Engineering — and, later, Engineering Physics joined them. The first engineering degrees from McMaster were Master of Engineering ( M.Eng.) degrees, with the first ones awarded in 1959. The first doctoral degrees (Ph.D.) were awarded in 1965.

In 1972 over 100 engineers received their Bachelor of Engineering degrees, with the annual total passing 200 by 1980, and in 2014 this number equaled 588.

1971 marked the start of the Engineering and Management program and later that decade, the Engineering and Society program began. In the early 1980s, the Electrical Engineering started its unique Computer Engineering program, and Mechanical Engineering began its program in Manufacturing Engineering.

The Faculty of Engineering began joint faculty appointments, research associates and collaborative research activities with McMaster's Faculty of Health Sciences. Courses in Biomedical Engineering were offered as electives in all engineering programs.

In 1997, the Faculty of Engineering began a joint venture with the Department of Engineering Technology at Mohawk College and created the Bachelor of Technology program.

Ranking

The 2017 Shanghai Ranking's Global Ranking of Academic Subjects ranked the Faculty's civil engineering program 29th in the world, and metallurgical engineering, computer science and engineering, and transportation science and technology programs within the top 75 around the globe.

Student life

The Faculty of Engineering at McMaster is known for its active student life. The McMaster Engineering Society (MES) is the student-run organization dedicated to fostering "the development of well-rounded undergraduate engineering students through accessible support of academics, athletics, and recreational and professional activities while maintaining the integrity and unique traditions of our faculty society." The MES offers an Engineering Co-op and Career Services (ECCS), which is a joint venture with the Faculty of Engineering. Engineering Co-op & Career Services connects students with employers, provides career-planning tools and resources, and provides opportunities for students to gain employment experience.

Some student-led groups within the faculty include: McMaster Ecocar 3, McMaster Formula Electric, Engineers Without Borders, McMaster Engineering Musical, McMaster Baja Racing and the McMaster Solar Car Team.

Traditions

Engineering students at McMaster University can purchase leather jackets with their faculty and graduation date embroidered on the arms and back of the coat. Since this tradition was established, these jackets have become a distinctive characteristic of McMaster Engineering on campus.

Student representatives to the faculty are chosen each year to lead the upcoming first years and represent the faculty of engineering at events. They typically dress in a red jumpsuit which they often personalize throughout their stay at McMaster Engineering. These representatives, nicknamed "Redsuits" or "Reds" are a fixture on campus and are known for their spirited behaviors'. The Redsuits have become synonymous with McMaster Engineering as well as McMaster University.

Undergraduate students produce an annual Engineering Musical every March that is written and directed by engineering students, with all of the 20-30 member cast and 10-15 member crew consisting of engineers. The musical takes a well known play, theme, or story and uses it as inspiration, but with a new script that includes jokes about professors, courses, faculty, and "arties".

The fireball

The fireball is the official symbol of McMaster Engineering. It historically comes from the coat of arms of Hamilton College. McMaster's Faculty of Engineering emerged from Hamilton College in 1958 and hence adopted a red fireball as its own emblem in 1960. The fireball symbol is used widely by both the faculty and students to represent everything from culture, to excellence in research and innovation, as well as the energy that cuts across science and engineering. In 2016, the Engineering Student Society of Conestoga College in Kitchener, Ontario applied to make the fireball a registered trademark.

Iron ring clock

The Iron Ring Clock is a clock of unusual design created by four Mechanical Engineering students at McMaster University. The clock was designed and built as a thesis project by Patrick Burton, Braden Kurczak, Michael Paddags, and Peter Whitred. It won the 2nd prize for Manufacturing at the 2003 Canadian Society for Mechanical Engineering Student Design Competition. The clock was donated to McMaster University in September 2003, at which time it was also put into commission. The design is based on the Iron Ring received by Canadian engineers during the Ritual of the Calling of an Engineer.

The clock was designed in large part in a four-month period at the end of 2002, with some features that were originally intended for an outdoor installation. The clock keeps time through the use of a synchronous alternating current motor, which regulates its speed based on the frequency of the electricity that it is fed. The top and bottom halves of the ring rotate independently, with the top half of the ring displaying the hours, and the bottom half the minutes. The minute ring moves constantly, while the hour ring increments once an hour through the use of a Geneva drive mechanism. The rings are driven through a gearbox that was designed and partly manufactured by the group. The two ring sections are made of forged stainless steel, with machined surfaces, and facets cut using a robotic six-axis water jet cutter. The central shield, which is the university coat of arms, is made of hand-crafted stained glass. The design of the clock was completed entirely with computer-aided design software, and CNC tools were used for components where the most precision was required. Although the clock was donated to McMaster University on completion, it is maintained by members of the team that built it.

To minimise costs, the team with help from technicians manufactured as many components as possible in an on-campus machine shop. The total cost of the clock was approximately $20,000 CAD, which was raised through donations, with donors listed on a nearby plaque.

Issues and lifetime wear

While it is quite well known on campus, the Iron Ring Clock is not always recognized as a clock. The most common criticism of the clock is that it is counterintuitive to read. (It must be read straight on, with the number on the top ring denoting the hour and the number on the bottom ring denoting the minute. If there is no number directly under the hour indicator, the minute must be inferred from the nearest two numbers.) As the rings move slowly, the clock has been mistaken for a static display. It has shown the wrong time in the past, due to events such as power outages or breakdowns; in 2006/2007, the clock stopped for three months due to motor bearing failure. In 2007, an uninterruptible power supply was installed to eliminate the problem with power outages. However, in the absence of such events the motor and mechanism have shown themselves to be quite accurate.

The clock has also had issues with mechanical wear; the use of steel ball bearings to support and position the rings has led to grooves being worn into the rings themselves, as the bearings are hardened steel and the rings are not. Some of these bearings have been replaced, as it becomes necessary; the group is considering future solutions to this problem. Other portions of the gear train are mounted on bronze bearings; these are expected to have a shorter wear life and will likely have to be replaced sooner than other gearbox components.

The Geneva wheel, made of aluminum for ease of manufacture, has also experienced some wear and will eventually need to be remade (the mechanism used in the clock differs slightly from the one shown in the graphic as it has only four spokes) .
