in a counter balanced system, do I need to account for both the load mass and the counter balance mass for acceleration? Answered
I have a simple 2 pulley system lifting a 2400lb mass. Imagine a chain lift, starting at the load mass, up over a sprocket, across to a second sprocket, then down to a 3000lb counter balance mass.
to move the load down, I'll need to apply 600+ lbf down on the load. To move the load up, I'll apply <600lbf to the load. That's simple. Now, during the move I need to STOP quickly. Do I need to account for only the 600lbs difference or the 5400lbs of moving mass?
