2142111 Statics – HW 3

Assignment Date: Friday 27 January 2012 Submission Date: Friday 3 February 2012

Name ID Section/ID

The force F = (6i+8j+24k) N creates a moment about point O of MO = (64i−26j−4k) N·m. If the force passes through a point having an x coordinate of 1 m, determine the y and z

coordinates of the point. Also, determine the perpendicular distance d from point O to the line of action of F.

(2)

Determine the moment of the force F about an axis extending between A and C. Express the result as a Cartesian vector.

If the magnitude of the resultant couple moment is 15 N·m, determine the magnitude F of the forces applied to the wrenches by both scalar and vector approaches.
