Due: next wed
Part II. Assisted Problem Solving -- 2 points each
Plan:
1) Notice that the x-component of the force can
not create a moment around the x-axis
2) Therefore, this can be converted into a 2D
problem. Sketch the force and position vector
in the y-z plane
3) Use the scalar method to find the moment
about the x axis
PLAN:
1) Use geometry to express the two unknown
moment arms in terms of d
2) Write the formula for sum of all moments in
figure and set = to -350
3) Solve for d (should be positive of course!)
Part III. Unassisted Problem Solving -- 3 points each
