Smart Cart Rod Stand

Use your Smart Cart as a force sensor by hanging it from a rod stand. Investigate Hooke's Law, study oscillations and more.

The rod clamp screws into the top of the Smart Cart in the mass tray and accepts a standard rod that can then be clamped to a rod and stand as shown.

Giant Smart Cart

3D print your own giant (and functional!) demonstration Smart Cart. This cart was too big for our printer so we had to print it in two halves that snap and glue together. The 3D printed façade snaps onto an actual PASCO Smart Cart, giving enough clearance for the real Smart Cart's wheels.  This means the built in encoder works as does the 3-axis accelerometer and gyro.  

Also included is a file called “Force Bracket” which screws into the force sensor on the real Smart Cart to extend the force sensor to the force sensor hole on the giant Smart Cart. Then you can install a ¼-20 hook to make the Smart Cart force sensor functional on the giant Smart Cart.

Note: The Giant Smart Cart is only a facade that is placed over an actual PASCO Smart Cart

The Giant Smart Cart is perfect for large scale demonstrations. And you can still collect and stream data for position, velocity, acceleration (x, y, z and resultant), rotation and forces just like a regular Smart Cart.

Print your own 3D Trusses and test them with PASCO's Materials Testing System.

Create your own 3D printed beams using free downloadable files. Beams and strusses shown here were created using an Ultimaker 2 3D Printer.

Once printed, simply insert your beams into our Materials Testing System for column buckling, 3-point bending, 4-point bending, tensile, and compression testing.

Four-point bend testing of printed trusses

What makes a truss stronger?

For a given length, is a taller truss or a shorter truss stronger? There are many ways for a student to investigate this, but one way is to print two versions like the ones shown here, and test them! The taller truss has diagonal members at 60° angles, compared to the shorter at 45°.

Print Your Own 3D Beams!

PASCO's Materials Testing System can do column buckling, compression and bending testing. Bending testing of printed hollow beams can be compared to that of solid beams, and graphed using PASCO Capstone Software.

Go further with the Renewable Energy Kit using custom designed blades and adapters

6in Blade:  Design your own blade or print a replacement using this template. Students can easily manipulate the airfoil shape to change the chamber, or adjust blade length and width.

STEM Adapter:  Start from scratch and design a wind blade or cups for a hydro turbine.
