Yp Atwood

This is the french version of YP Atwood. YP Atwood simulates a pulley (simple or double) driven by one or two suspended masses. This program is designed to study the kinematics and the dynamics of rotational motion with constant angular acceleration, and linear motion with constant acceleration. During the animation, up to 5 vectors (position, velocity, acceleration, tension and weight) and up to 7 graphs (position, velocity, acceleration, angular position, angular velocity, angular acceleration and energies vs time) can be displayed. System Requirements: YP Atwood runs on any Macintosh computer with MAC OS 7.0 or later. It needs about 250 Kb on your hard disk and 1 Mb of RAM.
