14.40. A uniform, solid metal disk of mass 6.50 kg and diam- eter 24.0 cm hangs in a horizontal plane, supported at its center by a vertical metal wire. You find that it requires a horizontal force of 4.23 N tangent to the rim of the disk to turn it by 3.34º, thus twist- ing the wire. You now remove this force and release the disk from rest. (a) What is the torsion constant for the metal wire? (b) What are the frequency and period of the torsional oscillations of the disk? (c) Write the equation of motion for o(t) for the disk.

9.77 - Two metal disks, one with radius R1 = 2.50 cm and mass M = Figure P9.77 0.80 kg and the other with radius R2 = 5.00 cm and mass M2 = 1.60 kg. are welded together and mounted on a frictionless axis through their common center (Fig. P9.77). (a) What is the total moment of inertia of the two disks? (b) A light string is wrapped around the edge of the smaller disk, and a 1.50-kg block is suspended from the free end of the string. If the block is released from rest at a distance of 2.00 m above the floor, what is its speed just before it strikes the floor? (C) Repeat part (b), this 1.50 kg time with the string wrapped around the edge of the larger disk. In which case is the final speed of the block greater? Explain.

Figure 19.45 9.45 .. CP A thin, light wire is wrapped around the rim of a wheel (Fig. E9.45). The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius R = 0.280 m. An object of mass m = 4.20 kg is suspended from the free end of the wire. The system is released from rest and the suspended object descends with constant accel- eration. If the suspended object moves downward a distance of 3.00 min 2.00 s, what is the mass of the wheel?
