Confused by Relative Motion? Let’s Breakdown the Steps
Watch our video! Typically, relative motion problems involve either two points, say A and B, moving independently of each other, or they involve two points on the same rigid body. The equations needed look the same. Also, relative motion equations can be written for “position”, “velocity”, or “acceleration” of the two points, though velocity and […]

It’s not only the best prep for the Mechanical PE Exams, it’s […]
Slider Rod Explained Using Common PE Exam Problem
Watch our video! The application of relative motion equations, especially those involving velocity, are some of the most powerful in dynamics. It may not involve finding magnitudes of forces in members, however, the motion of a member can be the key to solving for forces in those members. The key to relative motion equations is […]
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 […]
