- TL;DR Summary
- Hi, I'm working on a kinetic sculpture, rotating a piano 360 degrees within a circular framework. The piano has 2 pulley type wheels on each corner which fit into the round rails to maintain stability. My question--is the force needed to push/pull the piano on flat horizontal rails the same as it is to rotate it on round rails? Consider the piano to be balanced.
