Solve 2D Frames With Confidence
Watch our video! 2D Frames are typically two members connected at a pin, where one of the members is a two-force member. The other member is loaded such that it is not a two-force member, and is usually connected, like the two-force member, to the surroundings by a pin connection. Solving these kinds of problems […]
FEATURED TESTIMONIAL – “No Extra Nonsense”
“The DTC course was really helpful and I really appreciate how it made me feel like I could actually achieve and pass the PE exam (which I did thanks to you!). Your lessons are very clear and do not have extra nonsense. Thank you so much for everything.”– Erica Blackwell, PE, Anaheim, California Mechanical PE […]
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 […]

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 […]
DTC Has the Best Prices AND the Best Courses
Buying a PE Exam Review is a major purchase, so we keep our prices as low as possible and offer Pay Up Front, Test Drive, and Pay-As-You-Go payment options. But don’t let our lower prices fool you. DTC has the best PE Exam review courses out there. And with all our courses, you get up […]
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 […]
FEATURED TESTIMONIAL – “Gave Me the Courage to Pass the PE.”
“I attempted the PE Mechanical Machine Design & Materials Exam and failed, and since then I have been on and off preparing for the PE. I have tried PPI and School of PE programs, but none of them comes close to the detailed care and understanding that your program provides. DTC’s program gave me the […]
