Introductory Laboratory Apparatus

Apparatus Title: A Precision, Student-Controlled Turntable

Abstract The turntable converts calculations of angular position and velocity into reality. Answers such as "81.4°," "0.55 rad/s" or "tan-1(X/1.4)" become actual movements of a flashlight, mirror, lens or other device. The turntable costs less than $50 and works with any computer- or calculator-based interface with 4 digital output lines. Areas of application include vectors, rotational kinematics and dynamics, optics, and electricity and magnetism.
