A ceiling fan is turned on at a rate of 100 rpm. A spider is clinging to a blade of the fan. If the spider experiences a centripetal acceleration of greater than 0.3g , it will lose its grip on the blade. How far from the center of the fan can the spider safely go?
a=ω^2 r 〖(100*2π)/60〗^2*r=0.3g r=0.03m Is this correct? |

You are correct. I was wrong. Edited my error without sweeping it under the carpet. This post has been edited by boit on Sep 27 2011, 05:15 PM -------------------- Boit was last taught physics in class way back in 1994. Whatever he's learnt thereafter is purely by personal effort through this forum and searching the net. He is not an authority in any matter science. Unless with clear referrence, what he puts forward is his own understanding of what he has read and may not always be correct. Peace.
