Question
While circling the gardens you hear a noise coming from the direction of the chapel. As you enter the building, you discover that the cartel has sent its most famous assassin, Lucien Du Quesne, to ensure that you will be forever silenced. As you enter, Lucien is busy setting charges of PETN all around the sanctuary. Apparently, he intends to bring down the building during morning prayers in order to kill you and everyone else in the monastery. You pick up a thurible hanging nearby and head off to stop him. The thurible consists of a 0.75 kg pot, in which incense is burned, attached to a 1.0 m long massless chain. You spin the pot on the chain in a horizontal circle above your head. What tension (in N) must you apply through the chain to get the pot to spin at 110 rpm?
Explanation / Answer
Tension = M*r*w^2
where w = 110*pi/30
tension = 99.5185 N
