ma 2. A 1.80-kg connecting rod from a car engine is pivoted about a horizontal knife edge as shown in Figure below. The center of gravity of the rod was located by balancing and is 0.200 m from the pivot. When the rod is set into small- plitude oscillation, it makes 100 complete swings in 120 s. Calculate the moment of inertia of the rod about the -tation axis through the pivot. d- 0.200 in ce *​
