Question

After a period of use, one of the blades of a shredder has beenworn to a shape shown (looks like a skinny rectangular prism withthe ends rounded out along the far end and it has two holes with adistance of 80 mm from each other that are aligned and have an axisAA' going through the center of the first hole and BB' goingthrough the second hole) and is of mass 0.18 kg. Knowing that themass moments of inertia of the blade with respect to AA' and BB'axes are 0.320 g*m2 and 0.680 g*m2respectively, determine (a) the location of the centroidal axisGG', (b) the radius of gyration with respect to axis GG'.

Explanation / Answer

Your typed question (blades of shredder) does not match thequestion #131 in chapter 9 of the 8th ed. (the "blades ofshredder" question does match question # 134, though) So what are you looking for? EDIT: ahh, it might be that you have the SIversion and I am looking at the US units.
