Practice for Physics 1: Rotation of a rigid object about a fixed axis Task 5.1 P1. Calculate the moment of inertia of uniform disk of mass m, radius r, axis through the center and perpendicular to the plane of the disk P2. A uniform stick of mass M and length l is suspended horizontally with end B on the edge of a table, and the other end, A is held by hand. Point A is suddenly released. At the instant after release: a. What is the torque about B? b. What is the angular acceleration about B? c. What is the vertical acceleration of the center of mass? Ans. 3g/4 d. From part c, find by inspection the vertical force at B. Ans. mg/4 Task 5.2 P1. Find moment of inertia of uniform thin stick of mass m, length i, axis through the midpoint and perpendicular to the stick. P2. A Yo-Yo of mass ill has an axle of radius b and a spool of radius R. Its moment of inertia can be taken

Unformatted text preview: to be MR 2 /2. The Yo-Yo is placed upright on a table and the string is pulled with a horizontal force F as shown. The coefficient of friction between the Yo-Yo and the table is μ . What is the maximum value of Ii' for which the Yo-Yo will roll without slipping? Practice for Physics 1: Rotation of a rigid object about a fixed axis Task 5.3 P1. Consider a uniform drum of radius b, mass M, and moment of inertia I = Mb 2 /2 on a plane of angle β If the drum starts from rest and rolls without slipping, find the speed of its center of mass, V, after it has descended a height h.
