Document Summary

Test instructions are provided on the front page of the crowdmark booklet: the center of the1. 8-kg sphere c travels along the outer surface of a pipe d guided by arm oa, on a path described by (cid:1870)(cid:3404)0. 7sin(cid:2016). A small motor at point o forces the arm oa to rotate counterclockwise with a constant angular velocity of (cid:2016)(cid:4662)(cid:3404)2. 5 (cid:3045)(cid:3028)(cid:3031)(cid:3036)(cid:3028)(cid:3041)(cid:3046) (cid:3046) k=100 n/m and is compressed by 0. 33 m when = 63 degrees. The sphere c is in contact with only one edge of the slotted arm. Motion occurs in the horizontal plane such that the effects of gravity can be ignored. For = 63 degrees determine the following: 8: draw a large, clear free body diagram of the sphere. In figure i shown below, the spring with k = 100 n/m is relaxed. The spring is then compressed as shown in figure ii by moving the very small block b of mass 0. 5 kg to the left a distance .
