There is Pressure, and there is Pressure!
How the Bernoulli Equation Changed WWII My wife and I are avid fans of Brendan Fraser, his movie “Blast From The Past” being one of our favorites. When we learned he was starring in the recent movie “Pressure” we had to see it! Just from the ads for the movie, we knew it would be […]
Identify Two-Force Members to Simplify Equilibrium Problems
Watch our video! The term “two-force member” is really a misnomer, as there is actually only “one” unknown magnitude of a force involved. There are two forces acting on the member, however, they have the same magnitude but opposite directions. What makes problems with two-force members present easier is that you only have to do […]
Pulley-To-Block Motion Finally Explained Clearly
Watch our video! Two very interesting machine dynamics problems involve a pulley and a block, connected together by a cable that is wound around the outside of the pulley. This assembly forms a “simple hoist”. In one problem, the block is released from rest, causing the pulley to rotate, and in the other problem, a […]
Struggling With Rolling Wheel Dynamics? Let me help.
Watch our video! The kinematics of a rolling wheel can get complicated quickly, especially for the accelerations which you need to solve kinetics (also called dynamics) problems. One of the nice things about this topic is that there are only two variations. The first is a wheel that is being driven by an applied torque […]
Have a Tequila and Reduce Carbon Emissions in Buildings?
Who knew that relaxing with a drink could help save the planet? Holcim, a global building materials producer, proposes just that using biochar – converted from agave waste from producing tequila. Agave waste, or really any sort of plant or wood organic waste, is converted to biochar through a pyrolysis process using heat but without […]

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 […]
