Calculating rotational g force

  1. Dec 1, 2009 #1
    i observed a wind turbine w/ 253' diameter rotor (according to website http://www.hcpd.com/powerresources/wessingtonspringswindfarm/ ) and timed rotation was 3.3 seconds. if my calculations are correct the tip speed was a whopping 229 mph!!!!!

    is this enough info to calculate g forces at the tip???

    any insight appreciated 1953greg

    The acceleration is omega squared times the radius, where omega is the angular velocity.
    OR you can use velocity squared divided by radius.
    Be careful to keep your units right - use SI units and you are less likely to go wrong.
