Explanation Given information: Acceleration of the body is a _ _ . Angular velocity of the body is ω . Angular acceleration of the body is α . Position vector of particle P i is r i . Calculation: Acceleration of P i , a i = a _ _ + a i G a i = a _ _ + α r i + ω × ( ( − ω ) r i ) a i = a _ _ + α r i − ω 2 r i Effective force on the body, F = Δ m i a i F = Δ m i ( a _ _ + α r i − ω 2 r i ) F = Δ m i a _ _ + Δ m i α r i - Δ m i ω 2 r i Force consist of the terms, Δ m i a _ _ , Δ m i α r i a n d - Δ m i ω 2 r i . Total mass of the rigid body is the summation of small masses. ∑ Δ m i = m . G is the mass center of the body, ∑ Δ m i r i = m r i _ _ . So, ∑ Δ m i a i = m a _ _

A weight with mass mw=150 g is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. When the weight is released, it accelerates toward the floor as the thread unwinds. Assume that the spool can be treated as a uniform solid cylinder of radius R=4.00 cm and mass Ms=200 g. Find the magnitude ?a of the acceleration of the weight as it descends. Assume the thread has negligible mass and does not slip or stretch as it unwinds. Use ?=9.81 m/s2. Find the tension T in the thread.

Two flywheels are pinned to opposite ends of a metal bar. The smaller flywheel has a mass of 40 kg and a radius of 0.25 m. The larger flywheel has a mass of 275 kg and a radius of 1.75 m. The bar has a mass of 2 kg and a length of 3 m. A wooden plate acts as a ripcord by temporarily pressing it against the flywheels and rapidly translating it to the left at v = angular velocity of 25 rad/s and the large flywheel has an angular velocity of 3.5714285714286 rad/s. The flywheel-bar assembly is then set on frictionless ice such that the axes of rotation are perpendicular to the ice surface. 6.25 m/s. The plate is removed when the small flywheel has an The flywheel pins have Hk = 0.05, which eventually causes the flywheels to stop spinning relative to the metal bar. Angular momentum is conserved, so the whole assembly continues spinning as a rigid body about the center of mass. What is the final angular velocity of the assembly? rad/s. The flywheels and bar rotate about their combined center…
