A kid excitedly swings his foam cut-out hammer. If point P acts like a pin and the hammer rotates about kg that point, what is the moment of inertia of the hammer? The foam has a density of p = 160 m3 and a uniform thickness of t = 0.6 cm. Assume each cut-out is a rectangular plate and the foam acts as a rigid body. Plate A has a length lA 38 cm and width wA = 7 cm. Plate B has a length lB 9 cm and width wB = 16 ст. Plate C is identical to plate D, and has a length lc 15 cm and width wc = 10 cm.

The foam has a density of p uniform thickness of t = 0.6 cm. Assume each cut-out is a rectangular plate and the foam acts as a rigid body. Plate A has a length la = 38 cm and width wa = 7 cm. Plate has a length lB 9 ст and width wв — 16 ст. Plate C is identical to plate D, and has a length lc 15 cm and width wc = 10 cm. Plate C and D are attached to plate B such that their centers line up.
