Electrical saw with linear speed

  1. Apr 3, 2013 #1
    1. A 23 cm diameter circular saw blade spins at 3800 rpm. How fast would you have to push a straight hand saw to have the teeth move through the wood at the same rate as the circular saw teeth?



    2. Relevant equations
    v=wr
    τ=Iα
    τ=rFsinθ

    3. The attempt at a solution
    tried to multiply the rmp by the radius of the circular saw, but didn't give me a correct answer

    Could you show us your working.
    (Did you remember to use rad/s for the angular speed?)
