A kid excitedly swings his foam cut-out hammer. If point P acts like a pin and the hammer rotates about and a kg that point, what is the moment of inertia of the hammer? The foam has a density of p = 150 uniform thickness of t = 0.5 cm. Assume each cut-out is a rectangular plate and the foam acts as a rigid body. Plate A has a length 14 = 34 cm and width WA = 8 cm. Plate B has a length 1B = 8.5 cm and width wg = 30 cm. Plate C is identical to plate D, and has a length lc = 15 cm and width wo Plate C and D are attached to plate B such that their centers line up. Ip = 0.00758 x (kg) - m² 5 cm.
