12. Replace the force at A by an equivalent force and couple moment at P. Express the results on Cartesian vector form.

 A. F = (-50i+20j+30k) N, M = (50i-130j+170k) N-m B. F = (-50i+20j+30k) N, M = (-50i+60j+60k) N-m C. F = (50i-20j-30k) N, M = (-50i+130j-170k) N-m D. F = (50i-20j-30k) N, M = (50i-60j-60k) N-m

13. Replace the force at A by an equivalent force and couple moment at P. Express the results on Cartesian vector form.

 A. F = (60j-80k) lb, M = (20i+160j+120k) lb-ft B. F = (60j-80k) lb, M = (300j+560k) lb-ft C. F = (60j-80k) lb, M = 20i lb-ft D. F = (60j-80k) lb, M = (-160i-400j+120k) lb-ft

14. A force and couple act on the pipe assembly. Replace this system by an equivalent single resultant force. Specify the location of the resultant force along the y axis, measured from A. The pipe lies in the x-y plane.

 A. R = 25k lb, y = -0.9 ft B. R = 25k lb, y = 0.9 ft C. R = 25k lb, y = 3.9 ft D. R = 25k lb, y = -3.9 ft

15. Determine the couple moment. Use a vector analysis and express the result as a Cartesian vector.

 A. M = (800i-4800j-800k) lb-ft B. M = (4000i-2000j+4000k) lb-ft C. M = (-4000i+7000j-4000k) lb-ft D. M = (-800i-4800j-800k) lb-ft
