SUMMARY
The moment of inertia of a trebuchet can be calculated using the formula I = ∑i mi * ri², where mi represents the mass of each component and ri is the distance from the pivot point. In this discussion, the masses include a bucket with 63 pennies totaling 182 grams, a projectile mass of 1 gram, and an arm mass of 3 grams, with a total arm length of 24.6 cm. Participants emphasized the importance of accurately inputting these values into the equation to derive the correct moment of inertia.
