Significant Gifts and Contributors to Clarkson CEM

Howard E. Lechler was a well-known long-time Clayton and Gouverneur, New York resident who was born in Chicago, served in the US Army during WWII, and graduated from Clarkson University in May 1948 with a Bachelor of Science in Civil Engineering degree. Howard began his career as a Professor of Civil Engineering at Clarkson in 1948. John Rouse interviewed several candidates and saw Howards' management potential to start up the highly successful and now very large, multi-location, steel fabrication enterprise known today as Cives Steel Company with headquarters in Alpharetta, Georgia. Cives Steel, his life’s work, is one of the largest steel fabricators in the United States with six fabrication facilities strategically located throughout the US.

Howard went on to earn a Master of Science Engineering degree from Clarkson in 1953 and received an Honorary degree from Clarkson in 1978. In 2016, Clarkson was honored to receive a gift to endow the Construction Engineering Management (CEM) program’s director position in perpetuity. The CEM Program at Clarkson honors Howards’s legacy as a highly successful businessman, an avid sailor, hunter and fisherman, though a seat on the CEM advisory board for the Lechler/Cives Steel family as well as its commitment to the very best in construction education regionally and nationally.

Ronald P. Wells ‘68 received a bachelor’s degree in civil engineering from Clarkson College of Technology and led an extraordinary construction career, which began in 1968 with Peter Kiewit Sons’ Company. For the next twenty years, he worked in management capacities, from engineer to Vice President, building highways, bridges, industrial work, and heavy civil-related construction projects. In 1990, he became Vice President of Operations for Dillingham’s North American operations and simultaneously was President of Dillingham, Canada. After 30 years, Ron took on a new role as President and CEO of Stacy & Witbeck, Inc. Under Ron’s leadership, the firm grew from a regional construction company to a nationwide industry leader constructing light rail, commuter rail, streetcar, and other heavy civil transportation construction projects.

Ron was a proud leader of several construction industry associations, including The Beavers, and The Moles. He was also a member of the Good Knights Guild, Clarkson University's donor recognition program. He was both a loyal and leadership donor. Through his generosity, several critical efforts were accomplished including the hiring of its first Construction Engineering Management (CEM) Director, expansion of curriculum, a new emphasis on internships and placement, establishment of the CEM Advisory Board, and recognition of the Clarkson CEM Program throughout the construction industry. In memory of Ron, for his leadership and generous support of the Clarkson Construction Engineering Management program, in 2024 Clarkson named the CEM Director’s office in his honor. 

Sandy Ginsberg ‘54, HD ‘07 from Brooklyn, New York, graduated from Clarkson University in 1954 and was awarded an honorary doctorate in 2007. Sandy served in the Marine Corps Reserve and worked in the Construction Management industry as a Civil Engineer and Construction Executive. He was a life member of American Society of Civil Engineers, and a former president of Clarkson Alumni Association. His storied career spanned rebuilding and preserving some of America's most notable landmarks, including the Statue of Liberty and Ellis Island. In 1995, he received the Ellis Island Medal of Honor, recognizing his contributions to The American-Scandinavian Foundation, The American Scandinavian Society and Sons of Norway. In 2018, Clarkson University established a unique fund to perpetually resource and enable all expense paid field trips for students, often in partnership with CEM advisory board members and corporate partners.

Corporate Partners

The Clarkson CEM program at the undergraduate and graduate level is among the best in the nation with a consistent 100% year over year placement rate of our graduates in the construction industry.  Our strong relationship with partners provides many opportunities for our students and assurance our students are graduating with the skills needed to be ready to enter the workforce.  Our students are sought after by many top firms because of the training, knowledge, and professional development they are known to receive while earning their degree at Clarkson

Rattleback Top

Rattleback Top

The rattleback is a top that defies convention.

It spins freely in one direction, but if spun in the other direction, its rotational motion becomes unstable; it starts to wobble and then will begin to spin in the opposite direction. In this regard, the rattleback seems to defy the physical law of conservation of angular momentum.

The rattleback is shaped as an elongated asymmetric semi-ellipsoid with a flat top. The unintuitive reversal of the rotational motion occurs because of its asymmetry. The asymmetry of the rattleback and frictional force from the table surface cause the rotational motion of the rattleback to become unstable. The friction transfers energy from the spinning (rotational energy) to the wobble (vibrational energy). The vibrational energy is then transferred back to rotational energy but in the preferred direction. Rotation in the preferred direction can also be initiated by pushing down on one end of the rattleback. This vibration is then transferred to a rotational energy.

The rattleback provides an opportunity to demonstrate many physics concepts in the classroom.

What are the axes of rotation? 

The rattleback has three primary axes of rotation. It can spin about its center vertical axis. It can roll about its horizontal long axis, and it can rock or wobble about its horizontal short axis. In boating terms, these are called yaw, roll and pitch.

  • Have your students identify these axes and sketch the shape of the rattleback in each case. The asymmetry in the shape can be seen when you look at the rattleback along the line of the long horizontal axis.

Why isn’t angular momentum conserved? 

Conservation of angular momentum is really just a special case of Newton’s second law of rotation when there is no net external torque (force applied at some distance from a rotation axis). In the case of the rattleback, however, there is a torque caused by the friction from the table top.

  • Try spinning the rattleback on various surfaces to illustrate the importance of friction.

What is Newton’s second law of rotation? dtLdext=Στ [1]

Angular momentum (L) is only conserved when there is no net external torque (∑Ŧext=). In the rattleback case, the torque comes from the frictional force, which acts in a direction opposite to the direction of the spinning. Angular momentum depends on the angular velocity (ω) and the rotational inertia (I): 

ωIL= [2] where ∑=iidMr2 [3]

The rotational inertia is defined by the distribution of mass (M) at a distance r from the axis of rotation. In rotation, objects behave differently based on the distribution of mass about the axis of rotation.

  • You can demonstrate this with a simpler example than the rattleback:      
    Take two PVC pipes of equal length. Add a high density material (like clay or steel washers) to the middle section of one. Divide the same mass in half and add equal parts to the end sections of the second pipe. The pipes will weigh the same, but the distribution of the mass      
    and, therefore, the rotational inertia will vary.
  • Have students quickly rotate the pipes back and forth (by gripping them at the middle) and describe the differences in their movement. Which is harder to rotate?

How does stability come into play? 

Objects in rotation preferentially spin around the axis with the smallest rotational inertia (eqn. [3]). Try spinning a book-sized block of wood in the air to demonstrate this. Spinning the wood around the longest or shortest axis of rotation is stable and the wood continues to spin. However, it wobbles when spun around the intermediate length axis.

The rattleback is more complicated in its instability due to the asymmetry around the axis with the smallest rotational inertia. However the instabilities are demonstrated when you tap the end of the rattleback. In this case, you are rotating the rattleback around the intermediate axis (short horizontal axis), which is the most unstable, similar to the book example. The wobble (rotation about the intermediate axis) is unstable and turns into rotation about the axis that is most stable.
 

Physics at Work

The rattleback is a great example of physics at work and the complexities of describing what appears to be a simple toy. Researchers have worked over decades to describe the motion of the rattleback in both physical and mathematical terms. Complicated mathematical equations and numerical models have been developed to simulate this behavior. But physicists who try to describe the physical behavior still struggle to intuitively understand it! The world’s most pressing problems in science, medicine, engineering and our natural environment are complex in much the same way.
