P.037. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The figure below shows four objects at the corners of a rectangle, connected by rods of negligible mass. The center of the rectangle lies at the origin of an xy-coordinate system. The width of the rectangle (along the x-axis) is 4.00 m, and the height (along the y-axis) is 6.00 m. Starting at the top left and going clockwise, the masses of the objects are m, - 3.30 kg, m2 - 2.50 kg, m3 = 4.30 kg, and ma = 1.70 kg. m 6.00 m m 4.00 m- (a) What is the moment of inertia (in kg . m2) of the system about the x-axis? 106.2 kg . m 2 (b) What is the moment of inertia (in kg . m2) of the system about the y-axis? 47.2 kg . m 2 (c) What is the moment of inertia (in kg . m2) of the system about an axis through O and perpendicular to the page (that is, the z-axis)? 42.545 X You may have neglected to square the distance r when finding the moment of inertia of each object. kg . m2
