Find the velocity V of a point on the rim of a wheel if r = 25 ft and omega = 7.4 rad/min.

Suppose a bicycle wheel is rotated about an axis through its rim and parallel to its axle. Choose the best explanation from among the following: I. The moment of inertia is greatest when an object is rotated about its center. II. The mass and shape of the wheel remain the same. III. Mass is farther from the axis when the wheel is rotated about the rim.

The radius of a merry-go-round is 11 m, and it takes 12 s to go around once. What is the speed of an atom in the outer rim?

Two points are located on a rigid wheel that is rotating with an increasing angular velocity about a fixed axis. The axis is perpendicular to the wheel at its center. Point 1 is located on the rim, and point 2 is halfway between the rim and the axis. At any given instant, which point (if either) has the greater tangential acceleration? Provide a reason for your answer.

Same as previous problem, but the beam is a 1-3/4 $\times 9-1 / 2$ I-joist, $w=100\ \mathrm{lb} / \mathrm{ft}$, and for (a), $L=16\ \mathrm{ft}$, while for (b), the allowable stress is $2950\ \text{psi}$.
