ES 04 F – Assignment Basic Operations of Force Systems Due on December 6, 2011. Submit at my desk (CE Dept) or in Class. On newsprint or bond paper 8.5” x 13” (Long)

1. Determine the magnitude of the components of force F = 56 N acting along and perpendicular to line AO

2. Given the force system shown, find:

a. The magnitude of the resultant force at A. b. The coordinate direction angles (direction cosines) of the resultant force at A. c. The resultant moment vector produced by the forces, FB and Fc about the base. Use

vector analysis. d. Smallest angle that the axis of the moment vector creates with the positive x axis.

Draw necessary diagrams and identify/highlight/state final answers.
