Homework Help: Forces on a wood-hacking machine knife

  1. Jan 5, 2012 #1
    Please refer to attached figure and help to give a formula of how to calculate the force "F". This is a task from real-world, which means that there was a damage with this machine and now it is necessary to know the mentioned force.
    The information that is available to complete the calculation: Rotation speed "V"; Knife distance from the center "R". This calculation shall consider two options: 1) the speed is constant; and 2) it is accelerating.
    So far I haven`t figured it out myself, although for people here it is probably quite easy.

    Thank You in advance!
