Handspeed held constant is an important aspect to keep in mind when reading about this topic in the book. What makes it more confusing though is how Homer talks about Handspeed changing when we change the Accumulator #3 angle, because that also affects the pulley size. __________________ tongzilla Last edited by tongzilla : 06-28-2006 at 10:50 PM. tongzilla View Public Profile Send a private message to tongzilla Find all posts by tongzilla
