( Hints: One of the quantities given in the figure is not needed. Pay attention to relative signs of torques from individual forces). 2. Assume that the wheel in the previous problem consists of two solid and uniform cylinders fused together by sides. The smaller cylinder (with radius a ) has a mass of 2 kg. The larger cylinder (with radius b ) has a mass of 5 kg. Find angular acceleration of the wheel. ( Hints: Figure out moment of inertia of the wheel and use Newton’s 2 nd law in angular form)
