Demonstrationsbeispiel Nr. 5: Ball im Kasten
A 9-page AEG-Telefunken application note presenting Demonstration Example No. 5, which simulates a 2D elastic ball bouncing inside a box under gravity, damping, and elastic wall forces on an analog computer. The document covers the mathematical formulation of motion in x- and y-directions, analog circuit diagrams for four machine variants (RAT 700/RA 741/RA 742, RA 770, and RA 800 HYBRID), and a complete potentiometer list with coefficient values and machine-specific pot numbers. A sine-cosine circle generator is used to display the ball as a moving dot on an oscilloscope in repetitive-run mode with a ~30-second period.
