The force of gravity acts on the baton in Fig. 10.11, and forces produce torques that cause a body’s angular velocity to change. Why, then, is the angular velocity of the baton in the figure constant?

Solution 14DQ Introduction We have to discuss, even if there is force, why the angular velocity of the bacon is constant. Step 1 Let us consider that the mass of the bacon balls on the bacon are m and m . Also suppose the 1 2 position of center of mass from m i1 r a1d from m is r 2 The2 we can write that m r = m r …………….(1) 1 1 2 2 Now the torque about the center of mass on the each mass is 1 r w1=1r m 1 …1….(2) And = r w = r m g …………(2) 2 2 2 2 2 Now using the equation (1) we can write that 1 2 That is the torque on both...
