YP Gear has been designed for the study of gear trains. This Macintosh software simulates the motion of a gear train composed of 2, 3 or 4 gears. The user controls the size of each gear.
New in this version:
Version 1.0 refused to work on a monitor set to millions of colors. This bug is now fixed.
Required Hardware and Software: YP Gear runs on any Macintosh computer with MAC OS 7.0 or later. It needs about 315 Kb on your hard disk and 1,2 Mb of RAM. The software runs on older models with 68000 processors (Mac Plus, Mac Classic), but simulations are slower.
Program operation:
When you launch YP Gear, the animation window is displayed on the screen: the animated simulation of the mechanism will appear in this window. Select item "Start Animation" in the "Animation" menu to start the animation. Use the "Dimensions of Mechanism" item in the "Animation" menu to change the size of each gear. Use the "Number of Gears" menu to change the number of gears in the animation. Use the "Angular Speed…" item from the "Animation" menu to know the ration of the angular speeds.
Using YP Gear:
Note: To help you explore all menus of the program, you may use balloon help (with the "?" menu, in the top right corner of the screen).
