Web20 feb. 2024 · moment of inertia mass times the square of perpendicular distance from the rotation axis; for a point mass, it is I=mr2 and, because any object can be built up from a … WebFind the moment of inertia of the rod and solid sphere combination about the two axes as shown below. The rod has length 0.5 m and mass 2.0 kg. The radius of the sphere is 20.0 cm and has mass 1.0 kg. Strategy Since we have a compound object in both cases, we can use the parallel-axis theorem to find the moment of inertia about each axis. WebRecall that the moment of inertia for a point particle is I = m r 2. The torque applied perpendicularly to the point mass in Figure 10.37 is therefore. τ = I α. The torque on the … shanghai bratislava
