The inclined plane rig (IPR) is an automated version of the classic inclined plane experiment. It is designed to illustrate principles such as static and dynamic friction, conservation of energy and acceleration due to gravity.
The IPR consists of a ramp that can be accurately tilted up to 38 degrees. One of three blocks, each bonded with a different friction material (nylon, acrylic, aluminium) can be released individually such that they slide down the length of the ramp. A linear displacement sensor accurately measures the distance travelled relative to the starting position and graphs it in real-time on the web user interface. First and second derivatives (velocity and acceleration) are also calculated and plotted against time. All measurements can be downloaded for post-processing.
