November 14th, 2006
Tangential Acceleration: A fan blade is rotating with a constant angular acceleration?
A fan blade is rotating with a constant angular acceleration of +12.8 rad/s2. At what point on the blade, as measured from the axis of rotation, does the magnitude of the tangential acceleration equal that of the acceleration due to gravity?
angular a = tangential a / r
r= tangential / angular
r= (9.8m/s^2) / (12.8rad/s^2)
r=0.765625m from axis of rotation
