Question

Rotational Inertia In this lab. we consider a pendulum formed from a meter stick pivoting about a point located a distance h from the CM as shown in the figure. The CM is at the center of the meter slick, and the CM rotational inertia is given in Table 10-2 of the text. Approximate the meter stick as a this rod of length L and mass M 1) what is the formula for the rotational inertia of the slick about its CM in terms of L & M? What is the formula of the rotational inertia of the slick about O a distance h from the CM in terms of L, h & M? Assume the mass of the slick is M = l00grams, L = 1 m, and calculate the rotational inertia for the values of h given in the table. Given that the period of oscillation of the meter stick pendulum is: calculate the values of T for the values of h & I given in the table.

Explanation / Answer

1) ML^2/12 2) ML^2/12 + Mh^2 3) Substitute the values of h in the above formula, M = 0.1kg, L = 1m 4) Substitute the values of I and h from question 3
