Part I. Drills -- 1 point each
Assignment 4 Chapter 4.1-4
Due: next wed
Part II. Assisted Problem Solving -- 2 points each
Plan:
1) The key to this is to realize F must point
along the line connecting A to B
2) Therefore, find the angle of Rba
(this could be done quite easily using info
from the drawing)
PLAN:
1) We are given a moment and asked to
determine b and c for block
2) Set up position vector Rpa using the
information from the drawing (use a=3,b and
c)
3) Set up and compute the cross product using
unknowns b and c.
4) The result for 3 should be set equal to the
given Mp. Use this to solve for b and c
Part III. Unassisted Problem Solving -- 3 points each
