Unformatted text preview: 1 Physics 1D03 Rotational Dynamics Rotational Dynamics Examples involving τ = Ι α Text sections 10.5, 10.7 Practice Problems: Chapter 10, Problems 35, 37, 39, 59 Physics 1D03 Quiz: Atwood’s Machine, again Two masses, m 1 > m 2 , are attached to the end of a light string which passes over a pulley. The pulley rotates on a frictionless horizontal axis and has mass M. How do the tensions in the two sections of the string compare? m 1 m 2 T 1 T 2 A) T 1 = T 2 B) T 1 < T 2 C) T 1 > T 2 2 Physics 1D03 Atwood’s Machine m 1 = 3 kg, m 2 = 2 kg, R = 10 cm. Find the accelerations, tensions if 1) the pulley is massless 2) the pulley has moment of inertia I = 0.04 kg m 2 . m 1 m 2 T 1 T 2 R Physics 1D03 A pulley of mass m is made of two disks welded together. The masses m 1 and m 2 are attached to two strings, and each string is wound around one of the disks. How does this change the problem? QUIZ: one mass starts to descend, while the other rises. The magnitudes of the accelerations of the masses obey the relation a) a 1 > a 2 b) a 1 = a 2 c) a 1 < a 2 d) not enough information R 2 R 1 m 1 m 2 3...
