1. Find the net torque on the wheel shown below about the axle through O if a=10cm and b=25cm. (Hints: One of the quantities given in the figure is not needed. Pay attention to relative signs of torques from individual forces). 10.0 N 30.04 12.0 N b 9.00 N 2. Assume that the wheel in the previous problem consists of two solid and uniform cylinders fused together. 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" law in angular form)
