Part I. Drills -- 1 point each
Assignment 12 Chapter 8.1-8.5
Due: next tue
Part II. Assisted Problem Solving -- 2 points each
Plan:
1) We are pulling wedge out, so wedge feels
friction force to the right at both surfaces.
2) Crate feels horizontal friction force to left
3) And vertical friction force pointing up
4) Use this FBD for wedge, and do your own FBD
for crate:
PLAN:
1) Based on problem statement, which is larger, F
or the weight of the cylinder?
2) Use the formula for belt friction.
Part III. Unassisted Problem Solving -- 3 points each
