Roller Coaster Fabrication Update…. It’s Awesome!
We are in full production mode on our new coaster launch system and I want to update you on the status. Exciting times here at the Mentored Engineer!
Tilley’s Terror Fabrication Update
I get that you don’t believe I’m actually building the world’s BEST backyard coaster. Well, It’s not finished yet, but we are making progress. Here are some pictures to prove
Exciting Cart Design Improvements for Our Backyard Coaster
A number of years ago, I heard that if you ever want to build your dream home; you will need to do it at least twice. Why, you learn things
Video – Capacitor Charging Issues – PLC Controls 4
In part 4 of our journey to the world’s Best Backyard Coaster, we encountered some issues with our capacitors. They are not charging evenly. So in order to get an
PLC Error Codes and Safe Failure Modes for My Coaster
Yes the last free video – sign up to see the rest of the series for creating Tilley’s Terror, our backyard roller coaster. We will discuss the launch system of
Coaster Launch Dog Motion on Test Bench with PID Controls
We are moving forward on our launch system for Tilley’s Terror. Our coaster launch, well at least the prototype, is taking shape as we are now able to move the
Some subjects, just need to be explained with more than words. Watch on YouTube. Same great content, but easier on the eyes.
Roller coasters have always intrigued me. The hills, turns, loops and drops leave me breathless, so I decided to design and build my own. See how I did it so you can make your own.
Ultimate Beam Calculator
Apply multiple loads to a beam and get the shear load, moment and deflection at all the critical points.
Cylinder Calculator
Calculate everything you can imagine on a cylinder: force, area, port size and buckling
Single Shear Pin Calculator
The simplest of all pinned joints, commonly used in the construction of buildings, bridges and other structures.
Hydraulic Hose Size Calculator
High back pressure? Working in cold weather? Find out how much energy you are wasting by not having the right hose size.
Double Shear Pin Calculator
Common in pivoting applications, the double shear joint eliminates moment in the axial members, making it better than single shear joints.
Pump / Motor Calculator
Need to size a hydraulic pump or motor? Enter what you know: pressure, flow, displacement, speed and torque; we'll calculate the rest.
Pin with Two loads
Many pivoting applications, like a crane pivot, are needed to withstand side moments. This calculator applies two loads on the pin.
Press Fit Calculator
Got a spherical bearing to press on a shaft? Make sure that you have enough force to install and pressure to keep it from rotating.
