Find the torque needed to accelerate the object in the figure to an angular velocity of 20 radians per second in 4 seconds if it starts at rest. The object consists of five spheres where r1 is .75 m and r2 is .45 m. The mass of center sphere is 100 kg and the mass of the little spheres around the outside are 30 kg. (hint: begin with finding the acceleration). The moment of inertia of a sphere is 2/5 mr² and the moment of inertia of a point mass traveling in an orbit is mr2. The object should spin around the center of the large sphere. (note: do not use the parallel axis theorem) r1 r2

A merry-go-round with a moment of inertia of 880kg⋅m2 experiences a force of 74.5N applied parallel to its edge, which is 3.35m from its axis of rotation. If the force lasts for 6.4s, what is the angular velocity of the merry-go-round, assuming it starts at rest? What is the angular momentum of the merry-go-round at this time?
A rope with a negligible mass has two blocks that are suspended over a pulley, m, and M, as shown in the image. The pulley can be considered as a uniform solid cylindrical disk. What is the equation for the net torque on the disc? Assume acceleration of blocks are a=(1/2)(9.8m/s2). What is the moment of inertia for this shape? (using the net torque equation from the above question, substitute the moment of inertia) The angular acceleration is correlated to the linear acceleration as α=r. Make the substitution into the torque equation in order to get the equation in terms of acceleration, α only.

A circular disk with a radius of 0.45 m is subject to 2 tangentially applied forces. The disc is fixed such that it will rotate about its center. Both forces produce a torque in the same direction. The mass of the disc is 0.59 kg. The moment of inertia of a disc is I MR? F1 = 2.3 N applied at the outer edge of the disc. %D F2 = 4.3 N applied at a distance of 0.21 from the center of the disc.
