Question

A certain type of propeller blade can be modeled as a thin uniformbar 2.60 m long and of mass 26.0kg that is free to rotate about africtionless axle perpendicular to the bar at its midpoint.
If a technician strikes this blade with a mallet 1.15m fromthe center with a 30.0N force perpendicular to the blade, find themaximum angular acceleration the blade could achieve.
Blade must be in a vertical position initially, so disregardgravity. I=1/2 mr^2
Thanks..

Explanation / Answer

I=1/2*MR2=1/2*26*2.62=87.88kgm2 =I=FR =30*1.15/87.88 =0.3925rad/s2 Hence we get by it. "Hope this helps!Best of luck for the rest of yourcoursework." Hence we get by it. "Hope this helps!Best of luck for the rest of yourcoursework."
