One of the wrenches in my toolbox has a mass of 0.25 kg, is 19 cmin length and has a center of mass located 7 cm from the heavier endof the wrench. I found that if suspended from a pivot point 4 cm fromthe lighter end of the wrench as shown above, it swings back andforth with a period of 0.5 s. What is the moment of inertia of thiswrench about this particular pivot point?
