A sector gear for a machine has 0.355 lb weight and center of gravity at point G. When the sector gear is supported at point O and is allowed to oscillate as a pendulum, 0.379 s is required for one full cycle of motion. Determine the mass moment of inertia about the axis perpendicular to the figur and passing through point A. Hint: See the helpful information margin note on p. 604.
