2024 F = ma Exam — Question 19

A wheel of radius R has a thin rim and four spokes, each of which have uniform density. m m m m 3m The entire rim has mass m, three of the spokes each have mass m, and the fourth spoke has mass 3m. The wheel is suspended on a horizontal frictionless axle passing through its center. If the wheel is slightly rotated from its equilibrium position, what is the angular frequency of small oscillations? r
