HW09 #1 Arm OA To solve particle kinetics problems, you need to be able to draw the correct FBD + Motion diagram and locate the correct angles. This former Quiz question tests your ability to do these steps. Particle A is pushed around a non-circular path by an extendable arm OA. The system lies in a vertical plane & friction exists between the path and A. The axes for particle A are given. 10 11 12 5 3 y+ +y 8 4 +0 3 +n +x 8 | side view of path !r-2-3cos(0) 7 6 (0) A. List the corresponding axes with each line above Axes for particle A +X +y +t +n +r +0 Line # C. In the boxes to the right, list TWO corresponding number locations (1-8) of the angle as defined in chapter 13. Part C: angle options B. List the correct axis and ± direction for each force. For example, the force F has been done for you. Force W: Weight force of gravity acting on particle A N: Normal force of path on A P: Pushing force from arm OA FF: Friction force from path Dir
