Physics 211 11/6 HW Handout Name_____________________ Fall 2002 Torque on a Disk Due Friday 11/8 1) A 3kg disk remains at rest against a rough wall. A string puts a tension force on the top of the disk. The wall puts a normal and a friction force on the disk. a) Draw an extended free body diagram of the disk, labeled as in class. Draw arrows to scale, thinking about

Unformatted text preview: F = ma = 0. b) Find all the forces in your free body diagram (magnitude only here, direction given by arrows in FBD). Show your reasoning. c) Find the minimum coefficient of static friction so that the disk will not slip against the wall. Show your reasoning. α = a = τ net = F net =...
