CP BIO ?T. rex. ?Model the leg of the ?T. rex ?in Example 14.10 (Section 14.6) as two uniform rods, each 1.55 m long, joined rigidly end to end. Let the lower rod have mass ?M ?and the upper rod mass 2?M?. The composite object is pivoted about the top of the upper rod. Compute the oscillation period of this object for small-amplitude oscillations. Compare your result to that of Example 14.10.
