Mechanical bench accessory 18:
Cart launcher:
The Spring Cart Launcher provides an economical way to launch carts in a repeatable fashion. It can be used for Hooke’s Law, collisions, and for Conservation of Energy.
It fits into the bed of a Dynamics Cart. To launch the cart, the plunger is pulled through the hole in the new endstop, compressing the spring, and then released.
To add repeatability, a second endstop can be used with the supplied pin to hold the plunger at a specified compression position. Three different strength springs are provided with the Spring Cart Launcher. Use with or without probeware.
Adjustable (spring compression vary in order to vary the speed)
Used for repeatability
Show a built-in scale to permit force calibration.
