2D Rigid Body Rotational Kinetics Newton’s 2nd law for pure rotation Σ τ o = I o α O : fixed pivot (rotation center) Example 1. A heavy metal sphere of mass M is mounted on the slender rod that has mass m and length L . The assembly is pivoted at point O and the size of the sphere is negligible compared with the length of the rod. At the position shown when the rod makes an angle θ with the horizontal, two forces are applied to the rod at its ends. Find the angular acceleration of the assembly at this position. F 2 F 1 θ b r O Note : The weight of a rigid body is acting at its center of mass, which is its geometric center for a uniform body. θ μ k 2. A block of mass
