A fan blade is rotating with a constant angular acceleration of +8.5 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?
Homework Answers
Consider a point at distance r from axis
Tangential acceleration, at = r = 8.5 r
For at =g = 9.8 m/s2
8.5 r = 9.8
Therefore,
r = 9.8÷8.5 = 1.15 m
