17-1. Determine the moment of inertia 1, for the slender rod. The rod's density p and cross-sectional area A are constant. Express the result in terms of the rod's total mass m.

The hammer consists of a cast iron head and wood handle. The iron head has 7000 kg/m density, and its shape is a rectangular prism with a circular hole. The wood handle has 500 kg/m3 density, and its shape is a circular cylinder. Determine the mass moment of inertia about the z axis and the corresponding radius of gyration.

6-85. Determine the moment of inertia /, of the area about the x axis. 100 mm-100 mm--150 mm 150 mm 15 mm 150 mm
