Homework Help: Physics

Posted by JAYZ on Friday, November 8, 2013 at 9:34pm.

Four point masses are arranged on the xy plane as follows.

Mass1 = 47.0 grams at x = 2.00 cm and y = 2.00 cm.

Mass2 = 55.0 grams at x = 0.00 cm and y = 4.00 cm.

Mass3 = 27.0 grams at x = -3.00 cm and y = -3.00 cm.

Mass4 = 45.0 grams at x = -1.00 cm and y = 2.00 cm.

What is the rotational inertia if this collection of masses is rotating about the x axis?
