The Neal Armstrong Award of Excellence – A Night to Remember
I had the honor of attending the presentation of the 2022 Neal Armstrong Award of Excellence to one of my former students at North Carolina State University, Trent Kingery, who had been one of my students in the Mechanical and Aerospace Engineering Department. He invited me to attend the Innovators Gala to be there when […]

Master Rolling Wheel Kinematics Once And For All
Watch our video! Kinematics is the study of the geometry of motion. Of the most common of moving objects, the rolling wheel is probably the most studied. This presentation shows how the velocity of particular points on a rolling wheel are determined using the relative motion equation. The most important aspect of the relative motion […]
Zero-force Members
Watch our video! Zero-force members are associated with idealized trusses where all the members of the truss are two-force members. This means the members are connected only by pins, only loaded at these pin connections, and are in either tension or compression. However, some of the members of the truss may have zero force acting […]
Learn to Solve Dynamics Problems Correctly
Watch our video! This presentation looks at the classic motion of a vehicle moving along a level road, where it could be speeding up or slowing down. In the example presented, the vehicle is slowing down due to its brakes, and in fact, we are told the wheels lock up. What is required in the […]
Welding Symbols
Watch our video! One of the most important standards in machine design are those specified by the American Welding Society. In one symbol critical information about the required weld is provided, such as location of the weld, type of weld, and size of the weld. If there are two sides to the connection, the symbol […]
Turn Complex Motion into Clear and Understandable Solutions
Watch our video! One of the most common and useful mechanisms in machine dynamics is the “slider-crank.” It has three elements: the “slider”, the “crank”, and the “connecting rod.” The slider is in “pure translation”, moving back and forth in a straight path. The crank is in “pure rotation”, moving in perfect circular motion. Then, […]
